Inferior
What is the primary role of the paleocerebellum?
Muscle tone and posture
What is the primary role of the neocerebellum?

What does the forebrain consist of?
Bilaterally paired diencephalon and cerebral hemisphere on each side
Where is the diencephalon found?
Between brainstem and cerebral hemisphere, rostral part of midbrain
What is the diencephalon composed of from dorsal to ventral?
Epithalamus, thalamus, subthalamus, hypothalamus
What are the three major nuclei associated with the thalamus’ functions?
Nuclei that transmit general and special sensory information to sensory cortices, nuclei that receive
impulses from cerebellum and basal ganglia to interface with motor regions and nuclei that have
connections with associative and limbic areas of the cortex

Caudal to optic chiasm
What extends from the apex of the tuber cinereum?
Pituitary stalk
What is found caudal to the tuner cinereum?
Mamillary bodies which house the mammillary nuclei of the hypothalamus
Where is the epithalamus found?
In front of the superior colliculus of midbrain
What does the epithalamus consist of?
Pineal gland and habenula
What hormone does the pineal gland produce?
Melatonin
What does the habenula have connections with?
Limbic system
Where is the subthalamus found?
Beneath the thalamus and behind the hypothalamus
What are the two cell groups associated with the subthalaus?
Subthalamic nucleus and zona incerta
Where si the subthalamic nucleus found?
