Q

What happens to the body while you’re asleep

A

HR, breathing slows
BP/Brain activity decreases
NREM

18
Q

Define REM

A

Rapid-eye movement/active sleep
Muscles paralyzed
Fast HR
Increased brain activity
Vivid dreams

19
Q

What are the functions of REM

A

Maturing infant brains
Processing info, learning, memory consolidation
Helps form new synapses in brain

20
Q

What are the functions of NREM
