title: [Reactions of neurons of the primary somatosensory cortex in cats to stimulation of different vibrissae].
abstract: Extracellular and intracellular reactions of 57 neurons from the vibrissal projection region in SI cortical zone were studied in cats. Intensity of both excitatory and inhibitory reactions decreased when stimulation of the receptive field was shifted from the centre to the periphery. A relative role of inhibition of vibrissal stimulation in inhibition/excitation interactions increased during such shift. Neurons recorded in the same microelectrode track had a common centre in the receptive field, but the dimensions of the receptive fields could differ substantially. Units with primary inhibition to the vibrissal stimulation were met.
