[Quantitative analysis of cerebral electrograms following administration of biogenic amines].

The influence of acetylcholine, norepinephrine and serotonin on the biopotentials of the cortical and subcortical-stem formations of the brain was studied in cats during a chronic experiment with monopolar electrodes. The accumulation of acetylcholine, norepinephrine and serotonin determines the formation of various profiles representing spectral characteristics of the brain electrograms, which, apparently, is conditioned by a temporal specificity of the action produced by the neuromediators on the post-synaptic membranes.
