[Endocrine control of olfactory reception].

There was studied the endocrine control of the first stage of olfactory reception. In the experiments with male castration it was detected that the olfactory receptor cells had a slow tonic influence on sex steroid hormones. The most dependent on the hormone control were the olfactory cells sensitive to natural stimuli. From the morphological data it was supposed that this influence was realized through the control of process of neurogenesis of the olfactory cells. On another experimental modelestral females. Which had quick changes of sex hormone level, it was detected that the reason for the olfactory sensitivity to odor variations during estrus cycle did not localized in the peripheral part of the olfactory system. Apparently the quick endocrine influence was realized at the central part of the olfactory system.
