[Selective reduction of the amplitude of the action potentials of neurons in the process of habituation].

Spike discharges of single neurons in the forebrain general cortex of the turtle were recorded extracellularly during habituation to light flashesmthe amplitude of spontaneous spikes, short-latent evoked spikes and spikes after the inhibitory pause was measuredmthe amplitude of short-latent evoked spikes significantly decreased during habtiuation while the background and postinhibitory spikes remained unchanged. It is supposed that the pattern of synapses activated by a definite stimulus may change the state of the elcetrically excitable neuronal membrane during habituation
