[Effect of anosmia on sex-related differences in conditioned avoidance in rats].
An influence of peripheral anosmia on sex-related differences in training and maintaining the conditioned avoidance (CA) behaviour in a shuttlle box was studied. Intact males have been shown to manifest conditioned behaviour earlier than intact females, whereas the degree of CA maintenance did not depend on an animal's sex. Prolonged anosmia facilitated training of conditional avoidance in both males and females, but it reversed the ratio of the amount of intersignal responses at anosmatic males to females versus the intact ones. Observed effects of anosmia are supposed to be realized due to the appropriate changes in the functional activity of the nuclei of the amygdaloid complex.
