The internal capsule is a large white matter structure located in which brain region?

• A. Cortex
• B. Subcortical structures
• C. Brainstem
• D. Cerebellum

Answer: (B)

The main idea is that the internal capsule is a major white matter tract tucked deep in the brain, in the subcortical region of the cerebral hemispheres. It sits between the basal ganglia (the lentiform nucleus and nearby structures) and the thalamus, so it lies beneath the cortex rather than within it. Its fibers carry information between the cortex and deeper regions like the brainstem and spinal cord (as well as to the thalamus), which is characteristic of subcortical white matter. It is not located in the cortex itself, nor is it a brainstem or cerebellar structure, even though many important motor and sensory pathways pass through it.
