LH lateral hypothalamus

When its destroyed one lacks hunger

VMH vetromedial hypothalamus

When VMH is destroyed one is very much hungry

Basal ganglia make our movements….

When destroyed….

smooth

results in parkinsons disease

Limbic system has 3 main parts

septal nuclei
amygdala
hippocampus

addictive

Amygdala

role in defensive/aggressive behaviors

Hippocampus

connected by….

learning and memory
