Fig. 6.
NaV1.5-like immunoreactivity (red) in the rat superior vestibular ganglion at different ages. Calretinin antibody (green) was added at P8 (B) and P21 (C) to label the relatively large somata of calyx-only afferents, which selectively innervate type I hair cells in central zones of vestibular epithelia. At P3 (A), no calretinin antibody was applied because vestibular afferents are not calretinin-immunopositive. Arrows, examples of bright NaV1.5 staining at each age. Arrowheads, dimmer staining. The 20-μm scale bar in C applies to A–C.
