An Emotional Hair Trigger, Often Misread--New York Times

Here's a blurb from the article: "Rather, affected individuals seem to be born with a quick and unduly sensitive emotional trigger. The condition appears to have both genetic and environmental underpinnings. Brain studies have indicated that the emotional center of the nervous system — the amygdala — may be overly reactive, while the part that reins in emotional reactions may be underactive."
I found this to be a really interesting article about the enigma that is Borderline Personality Disorder.
