Theory 12/Sleep-wake cycle/Termination phase
Waking Is an Arousal Threshold
The claim
Awakening occurs above a threshold in the ratio of external stimulus to arousal threshold, and the threshold varies with sleep stage.
01Mechanism
Arousal requires the stimulus to exceed a stage-dependent threshold; the ratio determines waking.
02Prediction
Awakening should track the ratio.
03Refutation
Awakening tracking clock time would remove the threshold.
