Within the framework of the flip-flop model, the VLPO represents the "sleep side," whereas the ARAS nodes represent the "arousal side." 13 The flip-flop model further predicts that orexin neurons of the lateral hypothalamus act as a "finger on the switch" to both prevent unwanted transitions into sleep and to stabilize wakefulness .

The model is based on previous "flip-flop" conceptual models for sleep/wake and REM/NREM and we explore whether the neuronal components in these flip-flop models, with the inclusion of a sleep-homeostatic process and the circadian pacemaker, are sufficient to account for the features of the sleep/wake cycle listed above.
