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 someone26abanana?
One way to find out is to watch the brain laugh. That"s what Dartmouth neuroscientist William Kelley did. He and his team had a number of volunteers watch an27of Seinfeld while being monitored by an MRI， a machine that allows researchers to see which parts of the brain are active at any 28 time. They then matched the MRI data with the laugh track to see how the brain changes when it"s 29 something funny. There"s no one "funny center" in the brain——but the findings were pretty.
When subjects were looking at something funny， the two regions in their left hemispheres lit up. From 31 studies these regions are known to be associated with resolving unclear meanings. Is there something in "getting it" that"s 32 the process by which we work with unclear information until we suddenly see the pattern in it?
A couple seconds later two other brain regions became 33， called the insula（ 岛叶 ） and the amygdala（ 扁桃腺 ）. The insula is associated with 34， so it seems likely that this is the brain feeling good when it gets the joke——the "ha-ha" response. The amygdala is associated with memory formation. As the researchers35，while you may not be able to remember every plot detail in an episode of a soap opera， you can probably remember the jokes. Humor stays with us， forming a lasting memory.
