Examples from otic capsule intact specimens showing antibody solutions had complete access to hair cells throughout each turn of the cochlea in perfusion (a-e) or immersion (f and g) fixed specimens. Crosssections from the apical (a), middle (b) and basal (c) turns showing labeled hair cells. Two other cases viewed in a nominal perimodiolar orientation (d and f) and when each is rendered in three-dimensions (e and g, respectively). Scale for a-c in c. AN, auditory nerve; IHC, inner hair cells; OHC, outer hair cells; OC, otic capsule; OW, oval window; RM, Reisner’s membrane; SGC, spiral ganglion cells; sl, spiral ligament; SM, scala media; ST, scala tympani; SV, scala vestibule; sv, stria vascularis; TC, tunnel of Corti; VHS, vestibular hair cells.
