Dr. Gregory Berns – TRANSCRIPT

How many of you are dog people? A show of hands. Excellent! How about cat people? OK, you guys can go to the break early. So, of the dog people and the cat people who want to be dog people, how many of you have thought, “Wouldn’t it be great to know what my dog is thinking?” I think everyone else already knows what their dog is thinking, right? I got into this project, and I’m going to tell you a little bit about how – This is basically a stupid dog trick story.

It really started with this dog named Newton, who was really my favorite dog. I’ve had many dogs through my life, but Newton was my favorite, and he lived to be about 15 years old. After he passed away, I thought, I have these tools, this MRI machine, that I have been using for decades to study human decision making and what motivates people, why haven’t we used this on other animals?

Certainly, other animals have many of the same feelings and motivations that people do. But this is kind of an area of science that people don’t like to talk about. So I embarked on this project about four years ago to try to figure out what dogs think, and specifically what dogs think of us. If we’re talking about humans, we have kind of two ways we can think about what other people are thinking: we can either ask them, and sometimes they will tell us if they know, and they want us to know what they are thinking; or we can observe actions, we can observe behaviors, we can try to infer things about what people are thinking from their actions.

With animals, and dogs, of course, we can’t really ask them. We can ask them, and we may think that they tell us, but we really don’t know what they’re thinking. So we’re kind of left with their behaviors: we can observe their actions, and we can try to infer what they are thinking. This is the foundation of behaviorism, and it’s been around since Pavlov. But there are, of course, very tricky issues here, and humans being humans, we tend to anthropomorphize everything. It’s kind of in this area that I became very interested in intrigued with the possibility of trying to figure out what dogs are thinking by using MRI. The technique is straightforward. It’s been around for decades.

The idea is: if we were studying a human, we would put a human in an MRI, have them do some type of task, and we’d measure blood flow or brain activity and then try to figure out what parts of the brain do what. Very straightforward, if you’ve had an MRI, it’s not terribly pleasant, but people will do it. How do we do this with other animals? How do we do it with a dog? I’m going to show you what we found.

Here’s a short video. It’s a what we call our training video, and it demonstrates how we did this. Before I start it, you’re going to see two dogs in this video. The first dog, Callie, is my dog. She was actually the replacement for Newton. She was adopted here in Atlanta from the Humane Society. We loved Newton so much; we could never get another pug, so Callie is the anti-pug. The other dog is McKenzie, a border collie. We just kind of get right into it. I’ll narrate as we go along. [Callie – Introduction to head coil] This’s Mark Spivak. He’s my partner in this endeavor, he’s a dog trainer.

The first thing that we had to do is figure out how do we get dogs to go into a tube, to put a head coil around their head to pick up the brain waves, and hold absolutely still. What you are seeing here, is that Callie is not a particularly obedient dog; she has no particularly special skills. But she does have one very good trait, and that is: she likes hot dogs. Mark is doing what we call clicker training. Every time she approximates what we want her to do, he clicks, and then she gets a hot dog. This’s the very first time she’s been introduced to the thing we call the head coil, and we didn’t know at this point whether this was even going to be possible.
