[Structural-functional organization of the brain amygdaloid complex in the dynamics of the estrous cycle].

As a result of amygdaloid complex detailed histology-physiological investigation statistically proved increase in estrus has been discovered in comparison with metestrus of medium size cell nucleus of some cortico-medial group structures and basolateral nucleus. The presence of differences in the level of estrogen binding of rostral and caudal parts of this brain structure, taking place both in male and female rats has been shown for the first time. It was also discovered the dependence of the level of estrogen binding on estrus stage.
