TS20: cerebral cortex intermediate zone	cortical interneuron	Present		S6A
TS20: cerebral cortex marginal layer	cortical interneuron	Present		S6A
TS20: cerebral cortex subventricular zone	cortical interneuron	Present		S6A
TS20: telencephalon	interneuron	Present	Regionally restricted	S6A	Expression was detected in the subpallium interneurons.

TS20: pallium	cortical interneuron	Present	Single cells	S6B	Expression was scarce in the miR-9-2/3 double mutant pallium, but apparently normal in the miR-9-2/3 double mutant subpallium, suggesting that interneurons were generated, but their migration was impaired in the miR-9-2/3 double mutants.
