[The interaction of impulses evoked by stimuli of different modality in neurons of the parietal association cortex].

Interaction of visual, auditory and electro-dermal signals in neurons of the parietal associative cortex was investigated in acute experiments on cats anesthetized by chloralose and nembutal. Two types of the interaction were found, one of which was characterized by inhibition or inhibition followed by facilitation of the response to testing stimuli, and the other by facilitation or facilitation followed by inhibition of background impulses. The interaction between signals of different modality is shown to depend on the properties of the neuron. Interaction ability in polysensory neurons was evidently higher than in bi- and monosensory ones.
