What Is Your Dog Thinking? Scientists Explore the Dog Brain

Many dog lovers have wondered, “What is my dog thinking? What if my dog could talk.” But because dogs can’t speak in a language people understand, individuals project their own thoughts and expectations about what their dog thinks. Now scientists at Emory University have moved a step closer to understanding the dog brain by capturing images of the canine thought processes.

What does man’s best friend think of people?

It’s too soon to answer this question or the many others dog owners (pet parents) have about their canine companions, but it’s about time an answer was found. Humans domesticated dogs thousands of years ago; in fact, a recent study from the University of Arizona describes a 33,000-year-old skull found in a Siberian mountain cave that is said to be among the oldest known evidence of dog domestication.

But in all those millennia, what do people know about what dogs think? Unfortunately, very little, but that may be beginning to change.

Now, deciphering the dog brain is a mission being pursued by Gregory Berns, director of the Emory Center for Neuropolicy and the main research of the new study. Bern and his team members are believed to be the first to produce images of the brain of fully awake, unrestrained dogs, which allow scientists to see canine thought processes.

The images were produced using functional magnetic resonance imaging (fMRI), a harmless and painless technique also used to explore the human brain. To protect the dogs’ ears from the noise emitted by the fMRI machine, the dogs were fitted with special ear muffs.

In this recent study, the scientists took images of the brains of two dogs (a two-year-old Feist and a three-year-old Border Collie) as they reacted to hand signals to which they had been trained to respond: one signal meant the dogs would get a treat, the other meant they would not.
