title: [Effect of picrotoxin on the receptive fields of neurons of the vibrissal projection area in the cerebral cortex of the cat].
abstract: Effects of microelectrophoretic injections of picrotoxin on the neuronal receptive fields were studied in the vibrissae projection zone of S1 area in the cerebral cortex of anaesthetized cats. The sensitivity of neurons to the direction of vibrissae bending was completely abolished after picrotoxin influence. These facts show a great importance of intracortical inhibitory processes in the receptive field organization.
