[Dependence of the reversal training of rats in a Y-maze and their haloperidol sensitivity on the estrous cycle phase].

In female rats estrous cycle related variations were found in reversal learning in a Y-maze. Low intersession fluctuations of errors and a high number of well relearning rats were obtained on the day of diestrus I as compared with estrus. The improvement of avoidance behaviour by haloperidol (0.

[Psychotropic substances and endocrine mechanisms: the effect on gonadal function].

Psychotropic drugs of different classes exhibit the ability to interfere in the sexual sphere. This is evidenced by clinical observations and the latest data concerning experimental research on pharmacological sensitivity of the central mechanisms controlling gonadal function. Both trend and stability of endocrine changes depend significantly on the profile of the neurotransmitter action of the drugs.
