Abnormal morphology of the brain in paqr5b−/−. (A) Comparison of the morphology of dissected brains between paqr5b+/+ and paqr5b−/− fish. The scale bars in the upper panels are 200 μm. The scale bars in the lower panels are 100 μm. Sagittal sections (B) and transverse sections (C) of the heads of paqr5b+/+ and paqr5b−/− are shown. The olfactory bulb (OB), telencephalon (Tel), tectum opticum (TeO) and corpus cerebeli (CCe) are indicated. Scale bars are 200 μm in sagittal sections. The scale bars are 50 μm in transverse sections.
