Physiology texts indicate that an animal deprived of sleep will face homeostasis disturbances, for example they can loose weight despite an increased caloric intake, and they will eventually die.
An animal deprived of REM sleep for several sleeping sessions in a row will show increased REM activity during subsequent sleep. Interrupting REM sleep repeatedly shows same disturbances in homeostasis as general sleep deprivation.
1. What is the role of the sleep in homeostasis . What is the mechanism ?
2. Is REM sleep essential in primates for homeostasis ? If yes, why, and what effects it mediates in addition NREM sleep stages.
3. Is there any correlation between total period of REM sleep in an adult and accumulated fatigue? For example, would an athlete who just competed in a probe like 100m sprint which requires maximum activation of motor cortex show significant increased REM sleep total time in the following sleep period? If yes, does it stand significant on its own , or it is just a consequence of longer total sleep ?
Just pointing to relevant reading materials is ok for an answer . Thanks
