Forebrain and Diencephalon Flashcards
1
Q
Where does the internal capsule become the corona radiata? Where is the transition from the anterior limb to the posterior limb?
A
- the interventricular foramen, which is at the most anterior part of the thalamus
- transition from ant. to post. after the genu
2
Q
What does the VPM/VPL of the thalamus project to?
A
somatosensory cortex (from trigeminal and solitary nuc.)
3
Q
What is Brodmann’s area 1-3?
A
- primary sensory
- *** “1-3 for sensory”
4
Q
What does the dorsomedial (DM) nucleus of the thalamus project to?

A
- primary visual
- “see the world at 17”
8
Q
What does the anterior nucleus of the thalamus project to?
A
to the cingulate gyrus of the cortex (from hippocampus)
9

A
- primary motor
- “4 is mo-TOR”
10
Q
