I'm a cat person. But I admit that dogs are streets ahead of cats when it comes to detecting their owner's moods.
Researchers scanned the brains of 11 remarkably well-trained pet dogs (and some people too) while they listened to lots of noises. Functionally similar areas of dog and human brains lit up at emotional human sounds such as laughing or crying. It's the first time such emotional recognition has been shown using brain scans outside of primates. It's cool, but does it tell us anything a dog owner doesn't already know?
