"The results show that dogs have an innate way to process faces in their brains, a quality that has previously only been well documented in humans and other primates," explained Gregory Berns, neuroscientist at Emory University and the senior author of the study.

For the study, the researchers focused on how dogs respond to faces versus everyday objects. The study involved dogs viewing both static images and video images on a screen while undergoing functional magnetic resonance imaging.

A region in dog's temporal lobe responded significantly more to movies of human faces than to movies of everyday objects. This same region responded similarly to still images of human faces and dog faces, yet significantly more to both human and dog faces than to images of everyday objects.

The researchers have dubbed the canine face processing region they identified the dog face area (DFA).Humans have at least three face processing regions in the brain, including the fusiform face area (FFA) which is associated with distinguishing faces from other objects.
