"The Limbic system area is the center that is in charge of the immediate reactions in the human brain and is located above the Brainstem. It receives the information from our sense organs even before our thinking brain - Neocortex has processed it, in order to operate emotional instincts that allow an immediate reaction such as self defense. The rational thought and more complex emotional processes are completed only after a few seconds.

After the rational processing, one of the two following will occur:

The person will rationalize his/her immediate emotions and thus justify his/her basic emotional assumption provided by the subconscious in the first milliseconds.
A second event occurs. It is also charged with emotion but has the opposite effect, forcing the person to change his/her basic primary emotional response."
