title: [Effect of the microiontophoretic feed of acetylcholine and noradrenaline on the neuronal reactivity of the motor cortex to specific stimuli].
abstract: In the forelimb area of the motor cortex after microiontophoretic injection of acetylcholine a group of nervous cells revealed more rapid, more stable and more effective reactions to afferent stimuli. The interrelation of impulsive activity of some of these neurons and electromyographic activity of forelimb muscles has given a possibility to propose that acetylcholine mobilizes the motor cortex for motor function regulations. The only result of noradrenaline application to motor cortex neurons was the prolongation of their responses to specific afferent stimulation.
