Some teasers: Chaser is a dog genius. He knows the names of more than 1,000 objects and you'll see him perform. Although I've previously seen Chaser do his thing, I'm still amazed at how much he knows. Brian Hare shows some simple tests to show how dogs and young humans follow human pointing, whereas bonobos do not. Dr. Hare also talks about the "love hormone," oxytocin, and its role in the formation of close social bonds. And, Dr. Berns shows how the use of fMRI's can show us what's happening in a dog brain. When dogs sniff human odors, not surprisingly, the olfactory (smell) part of their brain lights up. But, when his dog smelled Dr. Berns' own odor, the pleasure/reward centers lit up, indicating recognition of his odor and a corresponding emotional response.
I highly recommend this video to people of all ages. The combination of close observation along with non-invasive experiments and neuroimaging will surely help us learn more about what dogs are thinking and feeling, and what they want and need.
