WHAT HAPPENS IN THE BRAIN DURING SLEEP? What Happens During Each Stage of Sleep Have you ever wondered what actually happens ...

SIK3 has a part in regulating both the need for sleep and the amount of NREM (non-rapid-eye-movement) sleep we get each night. This gene is active in synapses—spaces between neurons where messages are ...

After NREM sleep, you move into the REM stage. After REM sleep, you start another cycle. If you get 8 hours of sleep each night, you usually go through four or five cycles.

Firstly, during NREM sleep, the researches saw “statistically significant reductions in power in the delta, theta and alpha frequency bands,” in the group who had consumed caffeine.

Dreams also occur in NREM sleep, especially stage 2, but these are generally thought to be more like overtures. Only in REM sleep do we encounter the full potent force of our nighttime madness.
