Sorry, I should have waited to post everything in one, but I wanted to get early thoughts in before posting more...
The woman characterized the amygdala for her own ego points..... Here are the actual facts about that part of the brain...
It is Primarily responsible for assigning emotional significance to encountered perceptions. In other words, reviews sense data and assigns emotional importance- i.e. particular threats. It produces discomfort until the threat is dealt with, it is NOT the fight or flight "panic" fear. Like when you get a bad feeling about something... that nagging feeling when you aren't doing your homework.
It also plays a part in Facial recognition, reading the emotions in facial expressions.
In Humans, the size of the Amygdala varies a lot throughout the population, quite more significantly than most body parts.
If someone has a abnormally small Amygdala they get symptoms such as : avoidance of eye contact, inability to perceive and process threats.
People who have a poorly/low functioning Amygdala get symptoms such as: Novelty seeking, Overeating, repetitive threat exposure, Docility, Increase sexual Drive, Lack of Empathy
Predator species tend to have much larger amygdalas than other species, mostly because the amount predators have to plan and perceive threats for the present and future.
People who have larger social groups tend to have larger amygdalas, they tend to have large complex social lives.
SO there are the facts, instead of just trying to label one aspect and not giving the big picture... I think the study is legitimate and it also makes sense.
