learning and memory (hippocampus). Has auditory complex for hearing,, olfactory association. Also important for facial recognition. Also has emotion areas.
Brain stem has how many cranial nerves nerves associated with it? How many on each part? Also a through way for what?

Explain the functional 3 areas of the cerebellum
- spinocerebellum (mostly anterior lobe)- control of muscle tone and coordination
- cerebrocerebellum (mostly posterior lobe)- motor planning, learning and memory of motor movements
- vestibulocerebellum (flocular nodular lobe)- balance, eye movements, posture adjustments
what is the diaphragma sella?
Has a hole for the pituitary stock
