[Change in the nociceptive reactions caused by dental pulp stimulation during excitation of the midbrain].
It was demonstrated in chronic experiments on cats that stimulation of certain midbrain regions decreased or fully depressed the pain reaction evoked by dental pulp stimulation. The antinociceptive effect depending on the parameters of the brain stimulation was shown in differential change of the separate motor and vegetative and emotional - behaviour components, forming a general pain reaction. A poststimulation analgesia was revealed and the dynamic of restoration of different pain manifestations after the cessation of brain stimulation was traced. Possible mechanism of the realization of the antinociceptive effect are discussed.
