[Effect of cholinergic substances on brain potentials induced by tooth pulp stimulation].
Introduction of the M-cholinomimetic -- arecoline into the ventricle of the rabbit's brain decreases and of the M-cholinolytic -- atropine -- increases the amplitude of primary responses in the sensomotor region of the cortex, arising out of stimulating the dental pulp. The N-cholinomimetic -- lobeline potentiates the evoked response of the brain cortex, whereas the N-cholinolytic -- beta-ethylene-splasmolytin -- depresses it. It is assumed that the region of the drugs action application are thalamic nuclei.
