[Nonsynaptic effect of the ECoG of the intact hemisphere on the impulse activity of neuronally isolated cortex].

In immobilized cats with neuronally-isolated cortex the nonsynaptic influence of the ECoG from the visual area of intact hemisphere upon unit activity of the visual and Clare-Bishop areas of the neuronally-isolated cortex was studied in the dark and during diffuse flash stimulation. Tonic unit reactions in the dark and tonic and phasic unit reactions to diffuse flash stimulation occurred in the visual and Clare-Bishop areas of the neuronally-isolated cortex. The possible nonsynaptic ECoG influence of the intact hemisphere on the activation of the neuronally-isolated cortical units is discussed.
