A delightful contribution from a guest author.
Dear readers, from time to time I am approached by other authors who have flattered me by asking if I would like to publish their Blog posts from time to time. So I have been doubly flattered by having two authors contact me in the last week.
So to the first. It is with great pleasure that I welcome Jane Brackman, Ph.D., author of the blog Doctor Barkman Speaks who will, from time to time, republish her posts on Learning from Dogs. I have no doubt that you will enjoy her scientific expertise regarding dogs
So today, please enjoy …
HOW DOGS THINK – NEW SCIENCE LOOKS INSIDE THEIR MINDS WITH MRI IMAGING
A couple of smart guys, Gregory Berns and Andrew Brooks of Emory University, watching a military dog assist Navy Seals as they overran the Osama Bin Laden compound, got a brilliant idea. If you can teach dogs to jump out of helicopters, surely dogs could be trained to enjoy themselves inside an fMRI machine while scientists calculate what the dogs are thinking by scanning their brains.
The researchers, who are dog-lovers, explained, “We want to understand the dog-human relationship, from the dog’s perspective. From the outset, we wanted to ensure the safety and comfort of the dogs. We wanted them to be unrestrained and go into the scanner willingly.”
So they recruited a professional dog trainer, Mark Spivak, and two companion dogs, a Feist Terrier named Callie and a Border Collie named McKenzie. The team said that both dogs were trained over several months to walk into an fMRI scanner and hold completely still while researchers measured their brain activity.
This is what the researchers wrote in the journal article that was published in PLOS last week:
Because of dogs’ prolonged evolution with humans, many of the canine cognitive skills are thought to represent a selection of traits that make dogs particularly sensitive to human cues. But how does the dog mind actually work? To develop a methodology to answer this question, we trained two dogs to remain motionless for the duration required to collect quality fMRI images by using positive reinforcement without sedation or physical restraints. The task was designed to determine which brain circuits differentially respond to human hand signals denoting the presence or absence of a food reward.
Eventually they hope to answer the more profound questions we all ask: Do dogs have empathy? Do they know when we are happy or sad? How much language do they really understand?” (And here’s one from me- When they pee on the carpet and we don’t find it until the next day, when we scold them do they know why we are scolding them?)

Jane Brackman, Ph. D.
Well, I don’t know about you but I found this a most fascinating article. All of us who live around dogs, both physically and emotionally, sense the closeness, may I use the word ‘magic’, of the relationships.
Take a look at the photograph below. Until I left the UK in 2008, a few of us owned a lovely old Piper Super Cub. It was a joy to fly. I used frequently to take Pharaoh to the grass airfield, Watchford Farm, up on the Devon moors. One day he showed such interest in the aircraft that I lifted him up to the passenger’s seat, strapped him in and taxied all over the grass airfield. This picture shows something that is difficult to explain otherwise – Pharaoh’s real joy at sharing the adventure. Of course, I didn’t fly with him, that would have been a step too far, but we did taxi almost up to take-off speed. Dr. Barkman, what do you make of that?
