[The effect of microiontophoretic administration of acetylcholine on evoked activity of visual cortex neurons subjected to direct cortical stimulation].
Reactions of visual cortical neurons (field 17) were studied in unanesthetized curarized cats. Neuronal responses to direct electric stimulation of the 18th and the 19th fields were studied after microiontophoretic administration of acetylcholine--chloride through 2-channel microelectrodes. The acetylcholine effect upon the primary discharge and the first trace pause, was specifically organized. Some neurons reacted differently under acetylcholine to stimulation of the 18th and the 19th fields. Participation of acetylcholine in information processing by transcortical mechanisms, is discussed.
