A Optogenetic stimulation (10 Hz) of mSTN neurons does not induce wakefulness during REM sleep, but stabilizes it, in the absence of predator cues. B Stimulation of mSTN neurons induces rapid arousal from REM sleep, when a predator cue is presented conjointly. C Sustained predator exposure induces a significant increase in total REM sleep. The REM sleep adaptation consists of increased total REM sleep time but shorter durations of individual REM sleep episodes and sleep architecture fragmentation. The fragmentation results from an increase in transitions between wake, NREM, and REM sleep states, with increased episodes of each state.
