Morphology of axonal tracts and Xlrobo2 expression domain in the diencephalon. a, b Coronal sections of the tadpole brain at stage 45, in which NeuroVue chips were inserted on the dorsal diencephalon and labeled neurons are shown in green. Blue staining shows nucleus labeled by DAPI. a Labeled axons (green), which correspond to the HC, are observed in the dorsal region of the diencephalon. b Labeled PC axons are observed in the dorsal diencephalon and labeled cell bodies are located ventral to the PC. This region is the presumptive nucleus of the tract of the PC (nTPC). (B’) High-magnification image of the red box in B. c, d Expression pattern of Xlrobo2 on coronal sections of the tadpole brain at stage 40. c and d are the slice of anterior and posterior diencephalon, respectively. d Xlrobo2 expression domain is observed in the nTPC (asterisk). Scale bars: 100 μm
