The most marked effect on the endocrine function render those negiotiations education in the brain which have close geographical or functional relationship with the reticular formation. This relationship becomes clear if we take into account that the reticular formation extends to the area of the hypothalamus. Therefore, any intervention that change the state and the tone of the reticular formation, must be reflected on the activity of the hypothalamus and, consequently, on the effects that it has on the endocrine function and primarily on the products and the impact of hormones by adenogipofiza. Thus, factors that inhibit the activity of the reticular formation, or destruction of certain sections of the latter inhibits the release of LH and prevents ovulation (Critchlow, 1958), and infantile animals leads to delay the onset of puberty, which may indicate a weakening of the production of FSH (N. 3. Maisuradze, 1960). Proceeding from the General properties of the reticular formation and its
physiological values in the body, it should be considered that its participation in monitoring of endocrine functions can be manifested not only in the immediate effects on the hypothalamic-pituitary relations, but also by changing the tone of various departments of the Central nervous system. On the state of the reticular formation is also influenced and cortical of the brain. Thus, the reticular formation serves as a connecting different parts of the brain system.
At present, it should be recognized that changes in germanophone pituitary observed at application of different impacts on negiotiations education of the brain, arise not from the direct impact of these structures on the pituitary gland, and are secondary, coming as a consequence of the initial changes in the life of the hypothalamus, i.e., mediated through the hypothalamus. "Implementation of the effects provided negiotiations formations brain and the endocrine glands is done, apparently, as a rule, through the hypothalamus"*", writes in his guide B. C. Aleshin.
The question about the influence of the sympathetic nerve impulses to the function of the hypothalamic-pituitary system will be discussed in detail in the main 6. However, it should still be noted that if until relatively recently, it was believed that the adenogipofiza practically deprived of nerve fibers, with the improvement of technology of detection our view has changed. Thus, many researchers discovered in adenogipofiza animals bezmaterny nerve fibers related to the sympathetic nervous system, and in 1938 Rasmussen has defined them in humans. According to Metuzals (1953), sympathetic fibers form around pituitary plexus, giving branches and adenogipofiza. Thus, it should be concluded that there is sufficient expressed material substrate, which may change activities adenogipofiza.
