Cornell research demonstrates integreation of canine sense of smell with vision

Cornell University researchers have provided the first documentation that dogs’ sense of smell is integrated with their vision and other unique parts of the brain, shedding new light on how dogs experience and navigate the world.

“We’ve never seen this connection between the nose and the occipital lobe, functionally the visual cortex in dogs, in any species,” said Pip Johnson, assistant professor of clinical sciences and senior author of “Extensive Connections of the Canine Olfactory Pathway Revealed by Tractography and Dissection,” published in The Journal of Neuroscience.

“When we walk into a room, we primarily use our vision to work out where the door is, who’s in the room, where the table is,” she said. “Whereas in dogs, this study shows that olfaction is really integrated with vision in terms of how they learn about their environment and orient themselves in it.”
