What happens when you tickle a rat? | Science News

Nerve cells in a rat’s somatosensory cortex respond to a tickling hand, action that may offer clues to how the brain creates joy, a new study proposes.
BigField GEG Tech's insight:

Tickle a rat and it will jump for joy, gleefully squeak and beg for more. In addition to describing these delightful reactions to a tickling hand, a new study identifies nerve cells in the brain that help turn rats into squirmy puddles of giggles.

The results, published November 11 in Science, offer insight into how the brain creates glee, an understudied emotion. “People really underrate the positive things — fun, happiness, joy,” says study coauthor Shimpei Ishiyama of Humboldt University of Berlin.
