3.02 the reality of fear

What I learned:I learned that approximately one in six adults over the age of 18 suffers from panic disorders brought on by attacks of fear. Just by being afraid, other bodily functions change, experiencing fear of merely perceiving it in others improved peoples attention and brain skills. What I know: I already knew that the fear hot spot is the amygdala, an almond shaped, very frightened people can withstand more pain than those hot experiencing fear. What I want to know more а bout: I would like to know more about the brain and why people become afraid.
