小编摘要：Why do you laugh ?Just cause you meet something funny ? Actually there is anything like funny center in your brain that make you laugh ……
Did you ever wonder what occurs inside your body when something funny happens? What is this thing we have in our brains that makes us say “ha-ha” when someone slips on a banana?
One way to find out is to watch the brainlaugh. That’s what Dartmouth neuroscientist William Kelley did. He and his teamhad a number of volunteers watch an episode of Seinfeld while being monitored byan MRI–that’s a machine that allows researchers to see which parts of the brainare active at any given time. They then synchronized the MRI data with thelaugh track to see how the brain changes when it’s registeringsomething funny. There’s no one “funny center” in the brain–but the findings were pretty suggestive.
When subjects were looking at somethingfunny, the two regions in their left hemispheres lit up. From previous studiesthese regions are known to be associated with resolving ambiguity. Is theresomething in “getting it” that’s related to the process by which we work with unclear informationuntil we suddenly see the pattern in it?
A couple seconds later two other brainregions became active, called the insula and the amygdala. The insula is associatedwith emotion, so it seems likely that this is the brain feeling good when itgets the joke–the “ha-ha” response.
The amygdala is associated with memoryformation. As the researchers point out, while you may not be able to rememberevery plot detail in a Seinfeld episode, you can probably remember the jokes.Humor stays with us, forming a lasting memory. Get it?
