Q

Function of Diencephalon

A

Processing center for information between sensory systems and cortex

22
Q

Location of Diencephalon

A

3rd ventricle is a median between the two thalami.

Thalamus is wall of ventricle

23
Q

Name nuclei of Thalamus (dorsal thalamus)

A
  1. Anterior
  2. Medial
  3. Lateral (dorsal and ventral tiers)
  4. Intralaminar
24
Q

Input/Output of Anterior Nuclei of Thalamus

A

Input: limbic-related projectoions from the mammillary bodies + hippocampus

Output: cingulate gyrus (via internal capsule)

25
Input/Output of Medial nucli Thalamus
Input: frontal lobe + substantia nigra Output: may be involved in controlling eye movement
26
Input/Output of Lateral Thalamic Nucli
Input/Outputs: widespread, vary by location. Dorsal Tier contains large pulvinar nucleus which is involved in vision Ventral tier relays somatosensory info
