GABAergic neurons onset

Boissard, R., Fort, P., Gervasoni, D., Barbagli, B. Luppi, P. H. (2003). Localization of the GABAergic and non-GABAergic neurons projecting to the sublaterodorsal nucleus and potentially gating paradoxical sleep onset. Eur. J. Neurosci. 18, 1627-39. 

Forebrain neurons would not be necessary for PS onset and maintenance. However, hypocretin and MCH hypothalamic neurons would participate in the homeostasis of PS through reciprocal connections and their respective excitatory and inhibitory projections on the brainstem monoaminergic and GABAergic PS-off neurons.
