High N brain centers
amygdala and hypothalamus

left prefrontal cortex
BAS brain area
dopamine
High for BAS; reward; High E, low C
Behavioral Inhibition System
Cues of punishment, anxiety, guilt
right prefrontal cortex
BIS brain area
GABA
Low for BIS, major inhibitor, lessens anxiety
Norepinephrine
High? for BIS, released in response to stress
Avoidance linked to
N linked to
E linked to
