[Effect of hyperactivation of the somatosensory cortex on pain syndrome of spinal origin in rats].

The cortical effects were studied in rats with abnormal pain. The spinal pain syndrome was induced by a generator of abnormally enhanced excitation in spinal dorsal cord. Hyperactivation of the somatosensory cortex was caused with penicillin. Cortical hyperactivation was shown to lead to the suppression of the pain syndrome.
