individual variations of your body to sleep at different times than other

Question 15

circadian low points time of day

Answer 15

1am-4am AND 1pm-4pm

Question 16

electroencephalogram

Answer 16

measures electrical wave-like patterns of activity in the brain through the scalp

Question 17

NREM 1

Answer 17

• lightest sleep
• common to see hallucinations
• generally only go into this stage when falling asleep

Question 18

NREM 2

Answer 18

• slightly deeper than NREM 1
• spend most time here

• physiology (heartbeat, breathing, etc) declines

• cognitive, emotional, perceptual, physical effects
