title: [Organization of afferent inputs of the parietal association area (field 7) and the Clare-Bishop zone of the neocortex in the cat].
abstract: The neuronal response of two parietal fields to the adequate stimuli of different modalities and direct electrical stimulation of various cerebral cortex fields were studied in semichronic experiments on cats. About 40% of the neurons in the Clare-Bishop area responded to the visual stimuli. Cells responding to the stimuli of different modalities were found in the Clare-Bishop area. Considerable percentage of cells in this area reacted to the direct electrical stimulation of area 17. 27% of the studied neurons in area 7 responded to the visual stimuli. As compared with the Clare-Bishop area only a small percentage of cells in area 7 reacted to the stimulation of the primary sensory fields. Electrical stimulation of area 7 was found to inhibit evoked and background activity of neurons in the Clare-Bishop area. A hypothesis is discussed that the areas in question are associative representation of two different sections of the visual system: retino-geniculo-cortical and retino-tecto-thalamo-cortical.
