Well, the amygdala is said to be the area of the brain that promotes fear in humans and that can be linked to paranoia, The amygdala is involved in making the person aware of the danger when
alerts it, but it probably has nothing to directly with
to due the fact that they are very small areas that aren't that complex. However, There might be a chance though. The temporal lobe seems like a universal area of the brain that controls a lot because of its size. It is said to control speech, audio and memory so I really don't know, but maybe
dominants have more developed temportal lobes. I personally believe they have a more developed prefrontal cortex.
