Machine learning gives glimpse of how a dog’s brain represents what it sees

Okay, this doesn’t have any obvious connection to living a long and healthy life, but I am a dog-lover and believe that there are more connections between our two species than meets the eye.

Scientists have decoded visual images from a dog’s brain, offering a first look at how the canine mind reconstructs what it sees. The Journal of Visualized Experiments published the research done at Emory University. 

The results suggest that dogs are more attuned to actions in their environment rather than to who or what is doing the action.

The researchers recorded the fMRI neural data for two awake, unrestrained dogs as they watched videos in three 30-minute sessions, for a total of 90 minutes. They then used a machine-learning algorithm to analyze the patterns in the neural data.

“We showed that we can monitor the activity in a dog’s brain while it is watching a video and, to at least a limited degree, reconstruct what it is looking at,” says Gregory Berns, Emory professor of psychology and corresponding author of the paper. “The fact that we are able to do that is remarkable.”
