[Responses of parietal cortex neurons during the process of sleep onset in the cat].
Neuronal responses in the cat parietal cortex to stimulation of thalamic radiation during transition from wakefulness to slow-wave sleep revealed a complex dynamics: the cyclic nature of responses at early sleep stages became more obvious with the enhancement of activity (during the "sleep spindles"); in subsequent stages inhibitory components prevailed. Three types of neurons with different response dynamics were revealed, the differences being due to their functional and hierarchical characteristics.
