[Monoaminergic component in the effect of D-9-tetrahydrocannabinol on conditioned reflex activity].

The involvement of monoaminergic system in the realization of the effect of D-9-hydrocannabinol on different parameters of the conditioned reflex was examined on cats. It appeared that the effect of D-9-cannabinol on the differentiation of long-term and short-term stimuli depends but to a different degree on the activity of both the serotoninergic and catecholaminergic systems. The effect of D-9-tetrahydrocannabinol on the rate of the performance of the conditioned reflex depends on the activity of the dopaminergic system.
