Eden, the area in purple according to wikipedia is associated with :
planning complex cognitive behavior, personality expression, decision making, and moderating social behaviour.[3] The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals.[4]
The most typical psychological term for functions carried out by the prefrontal cortex area is executive function. Executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, expectation based on actions, and social "control" (the ability to suppress urges that, if not suppressed, could lead to socially unacceptable outcomes). Frontal cortex supports concrete rule learning.
It is this area that when suppressed caused greater incidences of atheism. The clear suggestion is: Less regional brain function = More atheism.
What do you think of my examples of atheism being linked to and an absent father and emotional pain?
