sleep cycles
I thought that the sleep process in chapter 5 was very interesting. I had no idea there were so many stages of sleep. When you are awake there is a low voltage and high frequency beta waves. Next you become drowsy, and eventually move into stage 1 where theta waves are prominent. In stage 2 there are sleep spindles and mixed EEG activity. When stages 3 and 4 occur there are progressively more delta waves. REM sleep is where there is a low voltage and high frequency brain waves. This is when dreaming occurs. I didn't realize it took so many steps in order to dream.

I am especially interested in REM sleep. I had never heard of this stage before psychology. I also like how the farther you get away from REM sleep the less likely you are to remember your dreams when you wake up. I want to observe someone in REM sleep
ReplyDeleteI was also unaware of the different stages of sleep until I read this chapter. I was unaware of how dreams actually worked and why they occurred at certain stages of the night. Before this I figured a humans brain rested along with the body and also regained energy. I would also like to do a study of the eye movement during REM sleep because it seems interesting that peoples eyes are in constant motion while they are sleeping.
