 Rbfox2 is expressed broadly in a majority of neurons within the adult zebrafish telencephalon. (A) Schematic of adult zebrafish brain indicating plane of section through the mid-caudal telencephalon (lateral view). Region of section corresponding to dorsal telencephalon is indicated by asterisk (*), while region of section corresponding to ventral telencephalon is indicated by a double-asterisk (**). (B-B″) Rbfox2 is expressed broadly in neurons throughout the adult zebrafish dorsal telencephalon (pallium); staining was performed on alternating coronal sections to those in Fig. 2 to facilitate comparison with Rbfox1l. Approximate pallial subdivisions are indicated by dotted blue lines. (C-C″) Rbfox2 is expressed in neurons of the ventral telencephalon (sub-pallium); coronal section. Approximate boundary between dorsal and ventral telencephalon is indicated by dotted white line. (D-D″) Higher magnification view of neurons spanning Dm and Dc regions (coronal section). Abbreviations: Dm, medial zone of the dorsal telencephalon; Dc, central zone of the dorsal telencephalon; Dl, lateral zone of the dorsal telencephalon; Dp, posterior zone of the dorsal telencephalon; Vd, dorsal nucleus of the ventral telencephalon; Vv, ventral nucleus of the ventral telencephalon. Scale bar in B, C is 150 μm, and in D is 30 μm.
