Where is sarcasm detected in the brain?
So is it possible that Jon Stewart, who wields sarcasm like a machete on “The Daily Show,” has an unusually large right parahippocampal gyrus?
“His is probably just normal,” Dr. Rankin said. “The right parahippocampal gyrus is involved in detecting sarcasm, not being sarcastic.”
But, she quickly added, “I bet Jon Stewart has a huge right frontal lobe; that’s where the sense of humor is detected on M.R.I.”
A spokesman for Mr. Stewart said he would have no comment — not that a big-shot television star like Jon Stewart would care about the size of his neuroanatomy.
