arkypallidal neuron GPe MEIS2-SOX6 GABA arkypallidal neuron (Primate) CN MEIS2 GABA A arkypallidal neuron of the Primates brain. These cells are located in the striatum, external segment of globus pallidus . Reference transcriptomic data for this type can be found in the dataset/taxonomy - HMBA Basal Ganglia Consensus Taxonomy in cell set Group:GPe MEIS2-SOX6 GABA. Rationale for assigning this type to reference data: Mapping to the arkypallidal neuron is based on location (GPe), expression of GAD1/2, FOXP2, MEIS2, and NPAS1 and lack of expression of canonical pallidal markers NKX2-1 and LHX6, SST and PV. Location is inferred from registration of MerFish Data. Registration may be inaccurate, giving misleading location to adjacent anatomical regions. GPe MEIS2-SOX6 GABA
