Oxford professor explains what happens in human brains on seeing viral monkey Punch's videos

Morten Kringelbach, a professor of neuroscience at Oxford University, explained why people are finding videos of monkey Punch, who carries his orangutan plush toy, heartwarming. He said the brain's emotional part - the orbitofrontal cortex - becomes active after a seventh of a second on seeing small babies or animals. "Once you have that experience, you go aww," he said.
