A

scramble frontal cortex to get thoughts out of your head

24
Q

Anterior Cingulotomy

A

separating cingulate gyrus from other parts of limbic and frontal cortex
ridding of attending to negative thoughts

25
Q

General Adaptation Syndrome

A

response cycle to stressors
Phase I: white blood cells pumped out
Phase II: Stage of Resistance
Phase III: Stage of Exaustion

26
Q

Activation synthesis theory

A 
neurotransmitters coming from brain stem
dreams from REM
hippocampus working heavily
memory being etched in 
thus creating dreams
27
Q

Reticular Formation

A

1st step

light must diminish to start

28
Q

Acetylcholine (Cholinergic System)

comes from brain stem
supports sleep and movement of skeletal muscles
goes to brain with less light
activates dopaminergic system
