Muscle twitching during REM sleep contributes to the development of the body

Abstract

Animals must cultivate, refine, and sustain precise sensorimotor maps as their body progresses and alters during early growth and throughout their life. Many studies have proposed the possibility that spontaneous muscle twitching occurs only during REM ( or active ) sleep to help animals draw sensorimotor maps and improve spinal self-organization by activating skeletal muscle, which will be elaborated and discussed in this paper. First of all, this article explains the characteristics of muscle twitching, which make their function possible. Secondly, this paper expounds the effects of muscle twitching on the cerebellum and spine respectively, which provides strong evidence for the hypothesis that muscle twitching helps to improve the sensorimotor map. To conclude, REM sleep's spontaneous muscle twitching is indispensable for neurodevelopment. Further research could aid in comprehending neurodevelopmental disorders and even offer chances for early detection and treatment.
