Researchers find dogs' sense of smell is linked to vision

New Delhi, July 21 (ANI): The first documentation that dogs' sense of smell is integrated with their vision and other unique parts of the brain has been provided by Cornell University researchers. It sheds new light on how dogs experience and navigate the world. The findings by the researchers were published in the journal JNeurosci. “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’. “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.” Johnson and her team found connections where the brain processes memory and emotion, which are similar to those in humans, as well as never-documented connections to the spinal cord and the occipital lobe that are not found in humans. The research corroborates her clinical experiences with blind dogs, who function remarkably well.
