[An analysis of the seasonal differences in the reaction of the hypothalamo-hypophyseal-ovarian system to the light regimen of the housing of animals after destruction of the lateral septal nucleus].
The investigation of the lateral septal nucleus (LSN) destruction participation in biorhythmological processes of the morphofunctional condition of the female genital apparatus of female rats was made in the experiments of juvenile female rats, i.e. such which are caused by the change of seasons of the year and light condition. It is shown that the reaction of the hypothalamo-hypophysis-ovary system (HHOS) on the changes of light conditions depends on the season of the year: in spring the regular darkness lends to the negative consequences in the sexual system, and in summer and autumn on the contrary, makes in more active. Regular lighting stimulates the HHOS only in spring. The realisation of photoperiodic processes in HHOS may be possible only in the presence of intact LSN. It is exposed that the reaction of HHOS of animals with destructive LSN in all seasons of the year and under different light conditions are opposite to those which take place in female rats with intact LSN.
