Regional distribution of mRNAs: a Htr2c/Pitx2; b Kcnab3/Pitx2; c Nxph4/Nxph1; d Calb2/Pitx2 co-localiztion analysis; e Schematic illustration of results presented by FISH: PSTN defined by Calb2 and absence of Kcnab3, and STNa/b/c/ds by Htr2c, Kcnab3, Nxph1 and scattered Calb2. STNds is further distinct from the STNa/b/c (Nxph1+/Nxph4+) by absence of Nxph4 (Nxph1+/Nxph4−). Distinct patterns in ZI defined by either Knab3 (primarily ventral ZI), Htr2c (primarily dorsal ZI), Calb2 (scattered in dorsal ZI) mRNAs. Scale bar 300 µm. Abbreviations: PSTN, Parasubthalamic nucleus; STN, Subthalamic nucleus; STNds, Subthalamic nucleus, dorsal strip; ZI, Zona incerta.
