title: [Habituation in the cortical division of the visceral analyzer].
abstract: Reactions of neurons without background activity ("silent" neurons) on long-lasting stimulation of mesenteric nerves were studied in cats anesthetized with chloralose 65-70 mg/kg) and paralyzed with flaxedile. It is shown that the "silent" neurons of the parietal and first projections areas are characterized by habituation during long-lasting stimulation of visceral nerves. Habituation developed faster in the parietal cortex and in the focus of maximal activity of the first somatosensory areas as compared to the second somatosensory area. The particularities of neuronal habituation in the cortex on visceral stimulation are discussed.
