[Aspects of the mediator nature of the effect of delta-9-tetrahydrocannabinol on evoked potentials of the cerebral cortex].

It has been shown on cats with the method of the conditional defensive reflexes and parallel recording of the bioelectric activity that the serotonin-negative and dopamine-positive substances restore the similarity of the amplitude-temporary parameters of evoked potentials in the visual, associative and the second comatosencory fields of the brain cortex, disturbed by delta-9-tetrahydrocannabinol injection. It has been also demonstrated that the serotoninergic substances influence the action of delta-9-tetrahydrocannabinol both on the early and late waves of evoked potentials whereas the dopaminergic substances influence the drug action only on the late waves.
