Forebrain
Thalamus, Hypothalamus, Amygdala, Hippocampus
Medulla
Control BP, HR, breathing
Pons
Facial expressions
Cerebellum
Coordinate muscle mvmts (Tracking target with eyes)
Thalamus
Receive sensory signals, send to area
Hypothalamus
Metabolic functions, body temp, sexual arousal, hunger, thirst, endocrine
Amygdala
Emotions
Hippocampus
memory processed then sent to other locations in cerebral cortex
