Detailed explanation-1: -The limbic system is also known to be active in REM sleep. In addition, during REM sleep limbic structures are active as a part of a closed-loop system, disengaged from overt behavioral mechanisms.
Detailed explanation-2: -Conclusions: Results suggest that REM sleep may increase reactivity to emotional stimuli in the short-term and this effect of REM sleep appears to facilitate emotional processing during subsequent nights leading to reduced intrusive picture memories in the long-term.
Detailed explanation-3: -During most stages of sleep, the thalamus becomes quiet, letting you tune out the external world. But during REM sleep, the thalamus is active, sending the cortex images, sounds, and other sensations that fill our dreams.
Detailed explanation-4: -During REM sleep, your eyes move rapidly behind your closed eyes, your heart rate speeds up, and your breathing becomes irregular. In contrast to other stages of sleep, in which your brain waves slow down, your brain is highly active during REM sleep, and your brain waves become more variable.
