GABAergic and glutamatergic domains and their gene-expression in the developing CNS. a Domains producing GABAergic and glutamatergic neurons. b Expression of TFs responsible for patterning of the proliferating progenitors. c Expression of proneural genes and their regulators, which control several aspects of neurogenesis. d Requirements for selector genes in the differentiation of the postmitotic GABAergic precursors. Note that the domain of selector gene expression can be larger than the domain of its function. For example, Gata2 is expressed in the ventral hindbrain, but not required for GABAergic fate selection there. Some of the GABAergic domains have not been associated with a selector gene function to date (labeled with question marks). e Known tangential migration routes and the TFs controlling the migratory behavior in GABAergic cells
