We already knew they were special. 🐶♥️🐶 Very cool new research on their smelling superpowers!!
Scientists at Cornell University have just discovered something extraordinary about dogs' brains, something that's never been found in any other species, including humans.
Dogs have a direct neural motorway connecting their sense of smell to their visual processing centre. They literally "see" with their noses.
Dr Pip Johnson was mapping neural pathways in dogs' brains when she found it. Using advanced MRI scans on 23 dogs, she expected to find the usual smell-to-memory connections that most mammals have.
Instead, she found massive information superhighways she'd never seen before.
"I just kept finding these huge pathways," she says. "They seem like information freeways running from the nose back into the brain."
Sniffing is a dog welfare need. 🥰
