Abstract

We show that most globus pallidus neurons, but very few neocortical interneurons, are generated from the ventral medial ganglionic eminence and dorsal preoptic area based on fate mapping using an Shh-Cre allele. The Shh-expressing subpallial lineage produces parvalbumin(+) GABAergic neurons, ChAT(+) cholinergic neurons, and oligodendrocytes. Loss of Nkx2-1 function from the Shh-expressing domain eliminated most globus pallidus neurons, whereas most cortical and striatal interneurons continued to be generated, except for striatal cholinergic neurons. Finally, our analysis provided evidence for a novel cellular component (Nkx2-1(-);Npas1(+)) of the globus pallidus.
