Figure 3. Histological analysis of GABA receptor subunit expression in swimming tadpole (stage 35) X. laevis embryos. Transverse 18-μm sections along the anterior-posterior axis, with dorsal to the top. A–E: GABAAα1 expression. F–J: GABAAα2 expression. K–O: GABAAα3 expression. P–T: GABAAα5 expression. U–Y: GABAB1 expression. Z-DD: GABAB2 expression. Prime letters: Magnified portions of sections. W′: Paraffin section to show lack of otic vesicle staining. fb, forebrain; mb, midbrain; hb, hindbrain; asc, anterior spinal cord; psc, posterior spinal cord; r, retina; sc, spinal cord; V, cranial ganglion V; VII, cranial ganglion VII,; IX, cranial ganglion IX: oe; olfactory epithelium; Pt, pituitary gland.
