[Analysis of the reactivity of the sensorimotor neurons of the rat cerebral cortex to acetylcholine].

Several types of cholinoceptive neurons have been identified in rat's sensomotor cortex according to response character to ionophoretical application of acetylcholine. The neurons investigated form continuous range according to duration of the excitatory component of reaction to transmitter application. It has been suggested that the duration of this component reflects the important functional properties of the nerve cell.
