Abstract
Experimental results and literature data point to the leading role of 4 brain structures in the genesis of emotional states and in the organization of goal-directed behavior. Owing to the functioning of the frontal parts of the neocortex, behavior is oriented to signals with a high probability of their reinforcement, and owing to the hypothalamus, to satisfaction of the dominant need. Unlike the neocortex the hippocampus is necessary for reactions to signals of low probability events, which is typical of the emotionally excited brain. The amygdala complex participates in creation of a balance, a dynamic co-existence between competing needs (motivations) and corresponding emotions. As a result, behavior becomes more plastic and adequate to the given situation.
