[Effect of serotonin on neuronal activity in the visual region of the cerebral cortex evoked by direct cortical stimulation].
Neuronal responses in cortical area 17 evoked by direct stimulation of areas 18 and 19 were investigated in acute experiments on unanesthetized cats. It was found that microiontophoretic application of serotonine changed late components of phasic neuronal responses and influenced the diffuse-tonic responses. The question on serotonin participation in trace responses and regulation of the excitability of visual cortex neurons is discussed.
