Did you ever wonder what happens when something funny happens? I mean, 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 brain laugh. That’s pretty much what scientist William Kelley did. He and his team had a number of volunteers watch an episode of a comedy while being monitored by an MRI—that’s a machine that allows researchers to see which parts of the brain are active at any given time. They then compared the MRI data with the laugh track to see how the brain changes when it’s registering something funny. There’s no one " funny center" in the brain—but the findings were pretty helpful. (33)When subjects were looking at something funny,the first thing that happened was that two regions in their left hemispheres lit up. From previous studies these regions are known to be associated. Is there something in" getting it" that’s related to the process by which we work with unclear information until we suddenly see the pattern in it? (34) A couple of seconds later two other brain regions became active. (35) One of them is associated with emotion,so it seems likely that this is the brain feeling good when it gets the joke—the "ha-ha" response. The other one is associated with memory formation. As the researchers point out,while you may not be a-ble to remember every plot detail in a comedy episode,you can probably remember the jokes. Humor stays with us, forming a lasting memory.
33. What happens first to the brain when one is looking at something funny?
34. What happens a couple of seconds after people look at something funny?
35. Why do people make a "ha-ha" response after looking at something funny?
