[Effect of the destruction of the oral and caudal trigeminal nuclei on pain sensitivity in cats].
Structural changes of nociceptive response after separate lesions of the oral and caudal trigeminal nuclei were studied in chronic experiments on adult cats. The lesion of the oral nucleus was shown to increase pain response and that of the caudal nucleus--to cause its inhibition. A relationship between the specific and non-specific projection systems of the brain in the development of pain is discussed.
