Rbfox1l is expressed in restricted populations of neurons in the adult zebrafish dorsal telencephalon and cerebellum, while Rbfox2 is expressed broadly throughout the brain. (A) Schematic of adult zebrafish brain (lateral view) with plane of section indicated for respective data panels B–M’. Asterisks indicate dorsal (*) and ventral (**) regions of sections imaged in (J-M′). (B–E) Rbfox1l expression in the adult zebrafish olfactory bulb and telencephalon (coronal sections, rostral to caudal). (F–I) Rbfox2 expression in the adult zebrafish olfactory bulb and telencephalon (on alternating sections to facilitate comparison with Rbfox1l) (coronal sections, rostral to caudal). (J-K′) Rbfox1l expression in the adult zebrafish midbrain, cerebellum, and medulla oblongata. *(D) and **(V) indicate dorsal and ventral regions of section imaged, respectively. (L-M′) Rbfox2 expression in the adult zebrafish midbrain, cerebellum, and medulla oblongata (on alternating sections to facilitate comparison with Rbfox1l) (coronal sections, rostral to caudal). Abbreviations: Medulla Ob., Medulla Oblongata. Scale bar for B-M′ is 300 μm.
