Which statement about the ganglionic eminences is correct?

• A. They generate cortical interneurons that migrate to the cortex
• B. They produce CSF
• C. They form the cerebellum
• D. They mediate motor neuron differentiation in spinal cord

Answer: (A)

Ganglionic eminences are ventral telencephalic regions that generate inhibitory interneurons destined for the cortex. These neurons are born in the medial and caudal ganglionic eminences and migrate tangentially into the developing cerebral cortex, where they become diverse GABAergic interneurons that help shape cortical circuits. This migratory path and origin explain why producing cortical interneurons that migrate to the cortex is the correct statement. CSF is produced by the choroid plexus in the ventricles, not by these structures. The cerebellum develops from hindbrain structures, not from the ganglionic eminences. Motor neuron differentiation in the spinal cord is driven by signals within the neural tube’s ventral region, not by these ventral forebrain zones.
