Abstract

Excitatory reactions of the motor cortex neurons during initiation of the conditioned placing are supposed to be based on NMDA receptor activation. The conditions needed for the NMDA receptor-driven channels to be opened by glutamate (mainly, postsynaptic hyperpolarization neutralization), are provided by the conditioned "arousal reaction" through the augmentation of cholinergic/noradrenergic bombardment of the motor cortex neurons.
