What is the thalamic reticular nuclei?
|
A thin sheet of cells surrounding thalamus on the lateral aspect - contains inhibitory neurons that project into the thalamus

|
|
List the fibers that are carried in the different parts of the internal capsule and understand the consequences of strokes or injury to a specific part of the internal capsule:
Anterior Limb |
- Carries thalamic fibers to/from Anterior Nucleus and cingulate gyrus
- Lateral Dorsal Nucleus nucleus and prefrontal cortex -Frontal cortex to brainstem (e.g., frontopontine) |
|
|
List the fibers that are carried in the different parts of the internal capsule and understand the consequences of strokes or injury to a specific part of the internal capsule:
