[The role of the posterior hypothalamus in the regulation of paradoxical sleep].
Posterior hypothalamus was found to take part in the inhibitory control of the paradoxical sleep executive mechanisms responsible for the ECoG desynchronisation and phasic events. Functional activity of the posterior hypothalamus seems to be at its lowest during the paradoxical sleep stage as characterised by phasic events and the ECoG desynchronisation, and increases during the stage with alpha-like activity in the ECoG and absence of phasic events, the latter having, probably, a "sentinel" function.
