Research: Dogs can see using their “nose”.

A new study has found that dogs may use their noses to “see” when their eyes are damaged.

According to the British “Sky News” network, a team of veterinarians from Cornell University in New York found that sight and smell are indeed linked in the brains of dogs, which is not the case with other species of animals.

The team performed MRI scans on several dogs of different breeds.

In their study, the researchers found that all studies revealed a “pathway” connecting the occipital lobe (the visual processing part of the brain) and the olfactory bulb (the part of the brain that processes smells). This pathway also includes the limbic system, a part of the brain involved in behavioral and emotional responses, they said.

The results, published in the journal Neuroscience, indicate that dogs’ sense of smell and vision are somehow complementary, meaning they can use their sense of smell to detect things you can’t see, the research team confirmed.

They point out that this is especially useful if dogs suffer from vision impairment or are completely lost.

Dr Philippa Johnson, who led the study, said: ‘When humans enter a room, they primarily use their eyes to identify the objects inside. But dogs seem to integrate smell with sight to recognize things around them, and decide to enter a particular place or room mainly after smelling it. He added: “A vet told me that sometimes he examines dogs and finds them to be completely blind, but the owners don’t believe him because the dogs behave naturally and don’t bump into anything in the house. We seem to have discovered the reason for this in our latest study.

Johnson pointed out that this discovery is the first of its kind and that this connection between the occipital lobe and the olfactory bulb has not been seen in any other animal.
