Using penduncles ( inferior, middle, superior)

39
Q

Penduncles are what?

A

Fibers

40
Q

Describe the epithalamus

Describe thalamus

A

Makes up 80% of diencephalon

Made of 2 large masses of grey matter
Transmits most sensory impulse(not smell) to the cerebral cortex
Starts the emotional responses to sensory impulses
