ASPECTS REGARDING THE NEUROBIOLOGY OF PSYCHO-AFFECTIVE FUNCTIONS

In this mini-review we were interested in analyzing the main achievements concerning the neurobiological substrate of the human psycho-affective functions. The cortico-subcortical areas implicated in the elaboration and the control of the sensorial and psycho-affective reactions of the human brain are described, as well as the neurobiological basis of the psychic and affective manifestations, with focus on the new achievements in understanding the genetic, morpho-chemical and electromagnetic bases of the psycho-affective and behavioral manifestations, both normal and pathological. It is known that emotional states like anxiety, fear or anger generate complex psycho-affective reactions that are controlled by the limbic system, which is called the emotional brain. This is connected with the polyneuronal circuits of the Papez loop, the hypothalamic-pituitary complex and the reticular formation of the brainstem. Some imagistic aspects concerning the implication of the amygdala and the cingulate gyrus in laughing and crying are mentioned, as well as the cerebral areas implicated in romantic and maternal love. Also, some electromagnetic manifestations of the brain are presented, introducing the concept of "electromagnetic plasma", as a possible component of the human brain activity.
