Beweise fehlen': Was Wikipedia über diesen viralen Mythos wirklich sagt

You've probably heard the myth that the sudden jerk when you fall asleep happens because our brain mistakes the relaxation of our muscles for falling out of a tree. This explanation is ubiquitous—and scientifically unproven. This video reveals the true origin of this oft-repeated myth, what neuroscience actually knows about the hypnotic jerk, and why the real story of our ancestors' tree-to-ground transition is far more interesting than the myth itself. Scientific sources used in this video: — Coolidge, F. L. (2006). "The effects of the tree-to-ground sleep transition in the evolution of cognition in early Homo." In the original paper, the tree-fall hypothesis for the hypnotic jerk is explicitly mentioned as one of several possible, unproven explanations ("e.g., Coolidge 2006"). Coolidge's actual scientific thesis concerns the broader connection between the transition to sleeping near the ground and cognitive evolution. — Wikipedia, article "Hypnic jerk": summarizes the current state of research, noting, among other things, that "evidence is lacking" for the tree-fall hypothesis. — On the hypothesis of the reticular system in the brainstem as the cause of the momentarily unstable motor control during the transition from wakefulness to sleep. — McGill University, Office for Science and Society: on the hypothesis that hypnotic jerks may be a "test signal" from the brain to check for the onset of sleep paralysis. Note on scientific context: The tree-to-ground transition theory itself (the actual shift of our ancestors from sleeping in trees to sleeping on the ground, presumably beginning with Homo erectus around two million years ago) is scientifically well-founded. The specific, popular claim that the nocturnal muscle jerk is a direct remnant of this transition, however, is unproven speculation that has spread primarily through repetition on the internet. This video deliberately identifies this distinction.
