[Effect of the somatosensory cortex on the development of deafferentation pain syndrome].

Effects of somatosensory cortex ablation and electrical stimulation on development of deafferentation pain syndrome in rats with sciatic nerve section have been studied. It has been demonstrated that both ablation and stimulation of somatosensory cortex delay the development of pain syndrome. The possible mechanisms of cortical effect on development of deafferentation pain are discussed.
