![]() Smelling in stereo: Your dog does amazing things with its noseWhile not technically color-blind, dogs have a very different way of seeing the world than humans. This TED video shows how dogs actually "see" the world not only with their eyes, but also their noses.
There's a common misconception out there that dogs are color-blind. They aren't, per se, though their range of colors is much more limited than that of humans. A TED video by Barnard psychology professor Alexandra Horowitz explains that our canine companions experience the world largely through their noses -- and in some incredible ways. For example, dogs have stereo smelling, which means each nostril smells independently so pooches get a sense both of what a particular smell is and where it's coming from. Dogs breathe in one hole in the nose and and out of another, so they're always bringing in olfactory information that gets sorted by hundreds of millions of olfactory sensors. Those sensors send tons of information to the olfactory bulb, which, relatively, is much larger in the dog's brain than in a human's.
Your dog's sense of smell is pretty amazing. ![]() |
