[Interaction of systems generating spindles and delta waves as a possible mechanism for the development of slow-wave sleep].

Certain correlations between spindling and delta-activity during slow-wave sleep (SWS) development have been studied in experiments on man and animals. Interaction between systems of delta-activity and spindling generation is discussed as a possible mechanism underlying development of SWS. Amplitude-modulated stimulation of non-specific thalamic structures has been shown to influence this interaction and development of sleep processes.
