title: [The effect of substance P on the neuronal activity of the antinociceptive system].
abstract: The experiments on rats showed that the 1 micrograms substance P injection to dorsal raphe nucleus caused prolonged (24 hours of study) analgetic effect--it enhances the reaction latent period to thermal nociceptive stimulation, intensifies the background impulse activity, rises the middle frequency of neuron discharges and creates high-frequency neurons as well as the neurons with burst impulse activity. The supposition is being confirmed that the mechanism of antinociceptive structures activation leads to analgesia caused by substance P.
