But all dog owners know that the odds of anxiety or depression if you have a dog or two around one are greatly reduced.
I’m chairing a discussion on depression at our local Humanists and Freethinkers group in eighteen days time; on January 18th, 2020. The core of my talk is a TED Talk given journalist Johann Hari in July of 2019.
This is how the talk is introduced.
In a moving talk, journalist Johann Hari shares fresh insights on the causes of depression and anxiety from experts around the world — as well as some exciting emerging solutions. “If you’re depressed or anxious, you’re not weak and you’re not crazy — you’re a human being with unmet needs,” Hari says.
There are sufficient numbers of people who follow this blog that it is likely that this talk will really engage a few of you. It’s twenty minutes long and very interesting!
Dogs use a part of their brain for processing numbers. But more than that, dogs use a similar brain region to process numbers as we humans do.
I found that fascinating.
This was one the results of reading a very interesting article published by The Smithsonian magazine earlier on in December.
Let me share it with you.

Dogs’ Brains Naturally Process Numbers, Just Like Ours
Scientists stuck 11 dogs in fMRI scanners to see if their brains had a knack for quantity

Sit. Stay. Fetch. Count?
Sort of. A team of scientists has found that dogs naturally process numbers in a similar brain region as humans, reports Virginia Morell for Science. While that doesn’t mean mutts can do math, it seems they have an innate sense of quantity, and may take notice when you put fewer treats in their bowl, according to a study published this week in Biology Letters.
Importantly, while other research has delved into similar stunts that scientists coaxed out of canines by rewarding them with treats, the new study suggests a knack for numbers is present in even untrained dogs—and could have deep evolutionary roots. This supports the idea that the ways in which animals process quantity in their brains may be “ancient and widespread among species,” Michael Beran, a psychologist at Georgia State University who wasn’t involved in the research, tells Morell.
To test pooches’ numerical prowess, a team led by Gregory Berns, a neuroscientist at Emory University, scanned the brains of 11 dogs of different breeds as they gazed at screens serially flashing different numbers of variably-sized dots. As the images flipped rapidly past, the researchers looked for activity in a region of the canine brain called the parietotemporal cortex, analogous to humans’ parietal cortex, which is known to help people rapidly process numbers. In humans, this region lights up on a functional magnetic resonance imaging (fMRI) scanner when numbers start to vary—a sign that cells are working hard to puzzle through the difference.
Something similar seems to apply to canines, the team found. When dogs hopped into the scanner, most of their parietotemporal cortices showed more activity when the numbers of dots flashed onto the screen changed (for instance, three small dots followed by ten big dots) than when they stayed the same (four small dots followed by four large dots).
The behavior wasn’t universal: 3 out of the researchers’ 11 test subjects failed to discern the difference. But it’s not surprising that the rest did, Krista Macpherson, a canine cognition researcher at Western University in Canada who wasn’t involved in the study, tells Morell.
Of course, approximating quantities of dots isn’t the same as solving complex mathematical equations, as our brains are equipped to do. But both behaviors stem from an inherent sense for numbers—something that appears to span the 80-million-year evolutionary gap between dogs and humans, the findings suggest.
Understanding how that basic ability might evolve into “higher” mathematical skills is a clear next step, study author Lauren Aulet, a psychologist at Emory University, says in a statement. Until then, we humans can count on the fact that we have plenty in common with our canine companions.
ooOOoo
An inherent sense for numbers. Wow!
This is yet another aspect of the relationship we have with our pooches that is deeper and closer than I imagined, and I’m sure I don’t only speak for myself.
Science has maybe found a clue to the ancestor of the dog and the wolf.
For an animal that means so much to us humans, the origins of the dog are still uncertain. Indeed, as this interesting article shows, the origins of the wolf are uncertain.

Was This 18,000-Year-Old Puppy Frozen in Siberian Permafrost the Ancestor of Wolves, Dogs or Both?

Meet Dogor, an 18,000-year-old pup unearthed in Siberian permafrost whose name means “friend” in the Yakut language. The remains of the prehistoric pup are puzzling researchers because genetic testing shows it’s not a wolf or a dog, meaning it could be an elusive ancestor of both.
Locals found the remains in the summer of 2018 in a frozen lump of ground near the Indigirka River, according to the North-Eastern Federal University in Yakutsk. Parts of the animal are incredibly well-preserved, including its head, nose, whiskers, eyelashes and mouth, revealing that it still had its milk teeth when it died. Researchers suggest the animal was just two months old when it passed, though they do not know the cause of death.
The pup is so well-preserved that researchers at the Centre for Palaeogenetics in Sweden were able to sequence the animal’s DNA using a piece of rib bone. The results found that Dogor was male, but even after two rounds of analysis the team could not determine whether he was a dog or a wolf.
“It’s normally relatively easy to tell the difference between the two,” David Stanton, a Centre for Palaeogenetics research fellow, tells Amy Woodyatt at CNN. “We have a lot of data from it already, and with that amount of data, you’d expect to tell if it was one or the other. The fact that we can’t might suggest that it’s from a population that was ancestral to both—to dogs and wolves.”
The find is exciting, regardless of whether Dogor turns out to be a common canine ancestor, an early dog, or an early wolf. Hannah Knowles at The Washington Post reports that Dogor comes from an interesting time in canine evolution, when wolf species were dying out and early dogs were beginning to emerge.
“As you go back in time, as you get closer to the point that dogs and wolves converge, [it becomes] harder to tell between the two,” Stanton tells Knowles.

The history of just how and when dogs split from wolves is unresolved. There’s a general agreement among scientists that modern gray wolves and dogs split from a common ancestor 15,000 to 40,000 years ago, explains Brian Handwerk previously for Smithsonian.com. How dogs became dogs, however, is contested. Some research suggests that dogs were domesticated by humans once, while other studies have found dogs were domesticated multiple times. Exactly where in the world wild canines became man’s best friend is also disputed. The origin of the human-animal bond has been traced to Mongolia, China and Europe.
Scientists disagree about how dogs ended up paired with people, too. Some suspect humans captured wolf pups and actively domesticated them. Others suggest that a strain of “friendly,” less aggressive wolves more or less domesticated themselves by hanging out near humans, gaining access to their leftover food.
Dorgor’s DNA could help unravel these mysteries. The team plans to do a third round of DNA testing that may help definitively place Dogor in the canine family tree, report Daria Litvinova and Roman Kutuko at the Associated Press.
ooOOoo
This is incredibly interesting, don’t you think?
Hopefully I will hear of that third round of DNA testing and, if so, will most definitely share it with you.
Good boy! Call it what you will; Coydog, Eastern Coyote, or Coymolf. Up close and personal, Taken in East Lyme Ct.
Ecologist and evolutionary biologist Javier Monzón analyzed the DNA of eastern coyotes and found the genes contain all three canids — dog, wolf, and coyote.
According to Monzón’s research, about 64% of the eastern coyote’s genome is coyote (Canis latrans), 13% gray wolf (Canis lupus), 13% Eastern wolf (Canis lycaon), and 10% dog (Canis familiaris).
Later on he added:
All my bird and nature photos are taken in South Eastern Ct. most with a Canon 7D Mark II or 5D Mark IV and Canon 100 to 400II THANK YOU. About 20 yards.
Then followed in response to my request for permission to republish:
Feel free, no problem!
Whatever happens to me in the next year, I truly hope I can continue to share such incredibly photographs with you.
Nature in all her glory!
Tomorrow is Christmas Day and I will be taking a short break, probably back on December 27th.
In terms of the Webformix internet cut-outs there has only been one noticeable break and that was yesterday early morning.
So I feel confident in posting this food recall notice that also came in yesterday.
ooOOoo
Dear Fellow Dog Lover,
I’m pleased to report there have been no dog food recalls since September 26.
However, for our many dog owners who also own a cat…
J. M. Smucker has recalled certain lots of Special Kitty canned cat food because the product contains ingredients that “do not meet the company’s quality and safety standards”.
Eating the affected food may cause nausea, vomiting or a host of other symptoms… some more severe… including death.
Some dog foods previously recalled may still be on store shelves… or in your own home. So, if you’ve missed any of the 11 recalls we’ve sent since July… be sure to visit our Dog Food Recalls page for full details.

Alex and Lisa have put together a remarkable video
Yesterday, in came an email from my son, Alex, about an amazing starling murmuration at the Royal Society for the Protection of Birds (RSPB).
Lisa took the video and together they uploaded it to YouTube.
Enjoy!
Having watched the amazing video I then did a little bit of research. I came quickly across the science of murmuration and have included it below.
Murmuration refers to the phenomenon that results when hundreds, sometimes thousands, of starlings fly in swooping, intricately coordinated patterns through the sky.
Maybe you’ve seen a murmuration video before. But this one is especially beautiful. It was shot earlier this month in Wales, at Cosmeston Lakes in the Vale of Glamorgan, and posted on Facebook by the BBC Cymru Wales. (It’s not included, Ed.)
It’s all about science. Just how do the starlings manage to fly in such an amazingly coordinated way?
A few years ago, George F. Young and his colleagues investigated starlings’ “remarkable ability to maintain cohesion as a group in highly uncertain environments and with limited, noisy information” — a nice description of what goes on in a murmuration.
Going in, Young et al. already knew that starlings pay attention to a fixed number of their neighbors in the flock, regardless of flock density — seven, to be exact. Their new contribution was to figure out that “when uncertainty in sensing is present, interacting with six or seven neighbors optimizes the balance between group cohesiveness and individual effort.”
Young et al. analyzed still shots from videos of starlings in flight (flock size ranging from 440 to 2,600), then used a highly mathematical approach and systems theory to reach their conclusion. Focusing on the birds’ ability to manage uncertainty while also maintaining consensus, they discovered that birds accomplish this (with the least effort) when each bird attends to seven neighbors.
I’m Tony I have been interested in eating healthy for more than 35 years. Unfortunately, my actions haven’t always matched my aims. As Mae West said, “I used to be Snow White, but I drifted.”
I drifted too, for a long time, but after writing posts for this blog for nearly 10 years, I have gotten good at it. I used the Lose It! App for a while (iPhone, iPad, Touch) a calorie counter that also breaks down nutrients and gives you a daily weight chart to demonstrate your progress. It’s not the only tool like this around, but it’s a good one. I think you are better off using a tool than not using one, especially if you are just embarking on a weight loss program.
Using that tool and practicing some self discipline I now have complete confidence in my ability to maintain a healthy body weight. I still need to work on the lean muscle mass thing, though. I love riding my bicycle and have no problem logging lots of miles and putting calories into the bank to free up my eating. I average around 100 miles a week. That covers a multitude of sins at the table. Biking is a wonderful cardio workout. Few people realize, however, it is also very stimulating for the brain. It’s a lot more fun than working with weights, but ya gotta do that, too. I write about the benefits of cardio exercise on the brain often in this blog as it is usually misunderstood and/or completely overlooked in most fitness writing. I had an aunt who died of Alzheimer’s, my mother who suffered from dementia in her final years, and my grandfather on my father’s side also had cognitive problems in his later years, so I am dead serious about protecting myself from mental decline. Check out my Page – Important facts about your brain – and exercise to read more about it.
I retired 19 years ago. I spent 20 years as a Reuters Correspondent and Editor after starting my career in men’s magazines. I taught journalism at Medill for a while and then wrote in the investment department of a major U.S. philanthropy where I spent my last few years managing $900 million in bond investments.
Now that I am retired, I have complete control over what I eat. My heart goes out to you folks who go to work every day. It is much harder to control your caloric intake. There are business lunches and dinners to attend, late days at the office, working through lunch as well as traveling. I think if I were still working I would seriously consider bringing lunch from home a day or two each week to keep a handle on my intake. With a fridge and microwave where you work, you are good to go.
When I started writing for this blog in March of 2010 I weighed 165 pounds, the lowest I had been in 15 years. I thought I had arrived at fitness and health. Now, in 2019, I weigh 155 pounds. That’s right, I have melted off a further 10 pounds from my best weight in years. My resting heart rate is under 50 beats per minute (bpm), a result of my cycling, but significantly under the ‘normal’ of 65 to 90 bpm for a guy in his upper 70’s. I have less than 16 percent body fat and a 31 inch waist (the first time since high school). I have reached this state of fitness and health following the ideas and techniques I write about in this blog. You can, too
When the blog started, I was talking the talk, over nine years later I am walking the walk. You can do the same. I am just a regular guy. If I can do it you can, too. Check out my page How to Lose Weight and Keep it Off for a start. Lots of excellent, practical principles there that I have learned and now apply to my daily life.
Just over 20 years ago my weight got out of control and I ballooned over 220 pounds. I took off 50 pounds in a year, but that only got me down to the mid-170’s. You can read How I lost 50 pounds in 52 weeks if you want chapter and verse.
When I retired, I started taking courses from The Great Courses. They include “Nutrition Made Clear” by Professor Roberta Anding. She has an MS in Nutrition and is a registered Dietitian and a certified specialist in sports dietetics. Another superb course is “Lifelong Health: Achieving Optimum Well-Being at any Age” by Doctor Anthony Goodman. He also teaches “The Myths of Nutrition and Fitness.” By now, in 2019, I have probably taken more than a dozen courses on mental and physical health and wellness as well as healthy aging.
I have about 40 games of backgammon going on the web. I was born January 26, 1940. I am an Aquarius and a senior citizen. At 79 years of age, I am healthier by far than I was over 20 years ago when I was in the work force and a relatively young man in my 50’s.
As a senior who presently is winning the war of the waistline, I am also grappling with the experience of aging. As part of this blog’s focus on good health I look seriously into aging and what can be done about it. I know there is no fountain of youth, but there are techniques for aging gracefully and, more importantly, retaining one’s mental powers. I promise to share with you everything I can find out about it.

Now Tony recently published a post that I found so interesting.
It’s all about improving one’s vision.

Walking improves vision – Study.
By Tony, November 25th, 2019
As a big fan of walking I was thrilled to learn of this further benefit to the Cinderella of the exercise world. Walking leads to an increase of peripheral visual input, according to a study from the University of Wurzburg.
How do we perceive our environment? What is the influence of sensory stimuli on the peripheral nervous system and what on the brain? Science has an interest in this question for many reasons. In the long term, insights from this research could contribute to a better understanding of diseases such as ADHD and Parkinson’s disease.
The topography of the EEG response (l) and its localization in the brain (r) show visual sensory processing during the walking conditions slow and normal – green and red, and standing – black. The image is credited to Barbara Händel.
Perception and the underlying neuronal activities are usually measured while subjects are sitting or lying, for example while doing magnetic resonance imaging. As a rule, the head is fixed and people are encouraged not to blink. The measurements therefore take place under well-controlled but rather unnatural conditions.
Shift of visual preference
When processing visual stimuli, however, it makes a difference whether the person is sitting or moving: When walking around, the peripheral part of the visual field shows enhanced processing compared to the central part. This can be proven both by the behaviorally measured perception of the test persons and by their brain response.
This shift in visual preference makes sense. “It is above all the peripheral visual input that provides information about the direction and speed of our movement and thus plays an important role for navigation,” says Dr. Barbara Händel. The neuroscientist from Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, and her colleague Dr. Liyu Cao have published their findings in PLOS Biology
“It was known from animals that increased body movements lead to an increased firing rate in visual areas of the brain,” says Dr. Händel. So far, there are only a few behavioural experiments available for humans that investigate the influence of movement on sensory brain areas. However, there is evidence that cognitive processes are linked to the behavioural state. “For example, some studies show that people learn better when they move,” says the JMU researcher. However, the underlying neuronal mechanisms have not yet been tested in detail.
Mobile EEG, sensors and video glasses
It is precisely such gaps in knowledge that Barbara Händel wants to close with her work. In order to explore the link between movement and perception, sophisticated technical equipment is necessary. While the test subjects walk around, they wear electrode caps and a small amplifier that records their brain waves. The EEG data are sent wirelessly to a laptop, which the subjects carry in a backpack. Motion sensors, video glasses, and a mobile device for recording eye movements complete the setting.
Quite an effort. “But we have to take this step if we want to understand human perceptual strategies during natural behavior,” says Dr. Händel. Research into perception during movement is still in its infancy. It is now up to science to ask clever questions and find out which of them can be answered with mobile technical equipment.
Many exciting research questions
Next, the JMU scientist wants to further investigate the effect of altered perception during movement. Does it only occur for visual input or possibly also in other sensory areas? Does it, in addition to navigation, perhaps also play a role in other cognitive processes such as memory and creativity?
All this is possible: experiments with rats have shown that these animals learn better, when they are in motion. And the idea that walking increases creativity has existed since ancient times. “For example, the Peripatetics, a philosophical school around Aristotle, usually were discussing while walking, from which their name derives,” says Barbara Händel.
There is also a connection between creativity and eye movements: “It is known that people blink more often the more creatively they solve a task. And we found that people also blink more often when they walk around compared to being at rest.” Obviously, there are many connections between the movements of the body, the eyes and the mental performance. Their research could reveal many more interesting aspects.
One dog year is not equivalent to seven human years, despite widespread use of the ratio for calculating the age of canine companions. Presumably, the ratio is based on the average lifespan of dogs being 10 years and humans being 70 years, it’s not quite so simple. The formula is not based on any real science and it was debunked by veterinarians years ago.
But geneticists digging into the mysteries of ageing have developed a new calculation to understand how our canine companions’ ages correspond to our own.
To understand how dogs age, the team looked at a phenomenon called DNA methylation. As mammals get older, their DNA picks up methyl groups that “stick” to their DNA. While these groups don’t change the DNA itself, they attach to the genetic molecule and can turn certain genes on or off, which is an important part of epigenetics, or the way environmental factors cause certain genes to express themselves.
Methlyation occurs at a relatively steady rate as humans age, which allows researchers to estimate a person’s age, a process they’ve dubbed the “epigenetic clock.”
In the new paper on dog years, which has yet to be peer reviewed and is currently posted on the preprint server bioRxiv, a team led by Tina Wang of the University of California, San Diego, compared the epigenetic clocks in people to canines to better understand the genes associated with aging. They picked dogs because most live in the same environments as humans and also receive some degree of medical care, like humans do.
The team looked at methylation rates in 104 Labrador retrievers between the ages of four weeks and 16 years old, reports Michelle Starr at Science Alert. They then compared them to published methylation profiles of 320 humans from age one to 103. (They also compared both to 133 mice methylation profiles.)
It turns out some parts of a dog’s life follows the same pattern as humans, though other longevity milestones don’t link up quite as nicely. For instance, the methylation rate showed a seven-week-old pup corresponds to a 9-month-old human baby, and both species begin to get their first teeth at this time.
But the comparison breaks down after early puppyhood. The dog clock ticks much faster with pups speeding through puberty and reaching sexual maturity within their first year. Then, the dog’s epigenetic clock slows down as the dog ages, and begins to match up with humans again in its later years.
Overall, the average 12-year lifespan of a Labrador lined up with the average worldwide lifespan of humans, which is about 70 years.
While the study complicates the concept of “dog years,” it does show that the animals experience similar methylation processes as humans.
“We already knew that dogs get the same diseases and functional declines of aging that humans do, and this work provides evidence that similar molecular changes are also occurring during aging,” Matt Kaeberlein, a biogerontologist at the University of Washington who was not involved in the study, tells Virginia Morell at Science. “It’s a beautiful demonstration of the conserved features of the epigenetic age clocks shared by dogs and humans.”
The new formula for a dog’s ages based on the study requires a little more math than multiplying by seven. You multiply the natural logarithm of a dog’s age by 16, then add 31 [human_age = 16ln(dog_age) + 31].
According to the formula, a 2-year-old dog is the equivalent of a 42-year-old human, but things slow down after that. A 5-year-old dog is the equivalent of a 56.75 year old human, and a 10-year-old dog is the equivalent of 67.8-year-old person.
Evolutionary biologist Steve Austad of the University of Alabama in Birmingham, who was not involved in the study, tells Morell that he’s not too surprised that the epigenetic clock applies to dogs, too. He says that by studying different dog breeds with different lifespans the researchers may find some interesting results.
This formula is not the last word on dog years, however, especially since it only looked at one breed. Erika Mansourian, writing for the American Kennel Club, reports that the American Veterinary Medical Association says the accurate way to calculate dog years for a medium-sized dog is to assume the first year is equivalent to 15 years and age two adds another nine years. After that, each year of a dog’s life is equivalent to five human years. It doesn’t perfectly line up with the new formula, but both acknowledge that dogs age rapidly in their first years of life.
Whatever the case, dogs’ lives are all too short. That may be why people are excited about a project by the Dog Aging Project, which is currently recruiting 10,000 pets and their owners to participate in a new study that will look at the dogs’ health, gut microbes, diet and exercise to understand aging. And 500 lucky dogs will test out a new drug that may help slow the aging process, which could help us someday, too.

Could consciousness all come down to the way things vibrate?
Affiliate Guest in Psychology, University of California, Santa Barbara
Why is my awareness here, while yours is over there? Why is the universe split in two for each of us, into a subject and an infinity of objects? How is each of us our own center of experience, receiving information about the rest of the world out there? Why are some things conscious and others apparently not? Is a rat conscious? A gnat? A bacterium?
These questions are all aspects of the ancient “mind-body problem,” which asks, essentially: What is the relationship between mind and matter? It’s resisted a generally satisfying conclusion for thousands of years.
Chalmers thought the mind-body problem should be called “hard” in comparison to what, with tongue in cheek, he called the “easy” problems of neuroscience: How do neurons and the brain work at the physical level? Of course they’re not actually easy at all. But his point was that they’re relatively easy compared to the truly difficult problem of explaining how consciousness relates to matter.
Over the last decade, my colleague, University of California, Santa Barbara psychology professor Jonathan Schooler and I have developed what we call a “resonance theory of consciousness.” We suggest that resonance – another word for synchronized vibrations – is at the heart of not only human consciousness but also animal consciousness and of physical reality more generally. It sounds like something the hippies might have dreamed up – it’s all vibrations, man! – but stick with me.
How do things in nature – like flashing fireflies – spontaneously synchronize? Suzanne Tucker/Shutterstock.com
All about the vibrations
All things in our universe are constantly in motion, vibrating. Even objects that appear to be stationary are in fact vibrating, oscillating, resonating, at various frequencies. Resonance is a type of motion, characterized by oscillation between two states. And ultimately all matter is just vibrations of various underlying fields. As such, at every scale, all of nature vibrates.
Something interesting things happen when different vibrating things come together: They will often start, after a little while, to vibrate together at the same frequency. They “sync up,” sometimes in ways that can seem mysterious. This is described as the phenomenon of spontaneous self-organization.
When fireflies of certain species come together in large gatherings, they start flashing in sync, in ways that can still seem a little mystifying.
Lasers are produced when photons of the same power and frequency sync up.
The moon’s rotation is exactly synced with its orbit around the Earth such that we always see the same face.
Examining resonance leads to potentially deep insights about the nature of consciousness and about the universe more generally.
External electrodes can record a brain’s activity. vasara/Shutterstock.com
Sync inside your skull
Neuroscientists have identified sync in their research, too. Large-scale neuron firing occurs in human brains at measurable frequencies, with mammalian consciousness thought to be commonly associated with various kinds of neuronal sync.
Fries focuses on gamma, beta and theta waves. These labels refer to the speed of electrical oscillations in the brain, measured by electrodes placed on the outside of the skull. Groups of neurons produce these oscillations as they use electrochemical impulses to communicate with each other. It’s the speed and voltage of these signals that, when averaged, produce EEG waves that can be measured at signature cycles per second.
Each type of synchronized activity is associated with certain types of brain function. artellia/Shutterstock.com
Gamma waves are associated with large-scale coordinated activities like perception, meditation or focused consciousness; beta with maximum brain activity or arousal; and theta with relaxation or daydreaming. These three wave types work together to produce, or at least facilitate, various types of human consciousness, according to Fries. But the exact relationship between electrical brain waves and consciousness is still very much up for debate.
Fries calls his concept “communication through coherence.” For him, it’s all about neuronal synchronization. Synchronization, in terms of shared electrical oscillation rates, allows for smooth communication between neurons and groups of neurons. Without this kind of synchronized coherence, inputs arrive at random phases of the neuron excitability cycle and are ineffective, or at least much less effective, in communication.
A resonance theory of consciousness
Our resonance theory builds upon the work of Fries and many others, with a broader approach that can help to explain not only human and mammalian consciousness, but also consciousness more broadly.
Based on the observed behavior of the entities that surround us, from electrons to atoms to molecules, to bacteria to mice, bats, rats, and on, we suggest that all things may be viewed as at least a little conscious. This sounds strange at first blush, but “panpsychism” – the view that all matter has some associated consciousness – is an increasingly accepted position with respect to the nature of consciousness.
The panpsychist argues that consciousness did not emerge at some point during evolution. Rather, it’s always associated with matter and vice versa – they’re two sides of the same coin. But the large majority of the mind associated with the various types of matter in our universe is extremely rudimentary. An electron or an atom, for example, enjoys just a tiny amount of consciousness. But as matter becomes more interconnected and rich, so does the mind, and vice versa, according to this way of thinking.
Biological organisms can quickly exchange information through various biophysical pathways, both electrical and electrochemical. Non-biological structures can only exchange information internally using heat/thermal pathways – much slower and far less rich in information in comparison. Living things leverage their speedier information flows into larger-scale consciousness than what would occur in similar-size things like boulders or piles of sand, for example. There’s much greater internal connection and thus far more “going on” in biological structures than in a boulder or a pile of sand.
Under our approach, boulders and piles of sand are “mere aggregates,” just collections of highly rudimentary conscious entities at the atomic or molecular level only. That’s in contrast to what happens in biological life forms where the combinations of these micro-conscious entities together create a higher level macro-conscious entity. For us, this combination process is the hallmark of biological life.
The central thesis of our approach is this: the particular linkages that allow for large-scale consciousness – like those humans and other mammals enjoy – result from a shared resonance among many smaller constituents. The speed of the resonant waves that are present is the limiting factor that determines the size of each conscious entity in each moment.
As a particular shared resonance expands to more and more constituents, the new conscious entity that results from this resonance and combination grows larger and more complex. So the shared resonance in a human brain that achieves gamma synchrony, for example, includes a far larger number of neurons and neuronal connections than is the case for beta or theta rhythms alone.
What about larger inter-organism resonance like the cloud of fireflies with their little lights flashing in sync? Researchers think their bioluminescent resonance arises due to internal biological oscillators that automatically result in each firefly syncing up with its neighbors.
Is this group of fireflies enjoying a higher level of group consciousness? Probably not, since we can explain the phenomenon without recourse to any intelligence or consciousness. But in biological structures with the right kind of information pathways and processing power, these tendencies toward self-organization can and often do produce larger-scale conscious entities.
Our resonance theory of consciousness attempts to provide a unified framework that includes neuroscience, as well as more fundamental questions of neurobiology and biophysics, and also the philosophy of mind. It gets to the heart of the differences that matter when it comes to consciousness and the evolution of physical systems.
It is all about vibrations, but it’s also about the type of vibrations and, most importantly, about shared vibrations.
ooOOoo
This may require more than one read. Because, if you are interested in the subject I’m sure you will wish to read it again.
But the underlying premise is that, as was said earlier,: “all matter is just vibrations of various underlying fields.”
I’m pleased to report there have been no recalls since September 26.
However, for the many dog owners who also own a cat…
