A, M2 receptor immunostaining (red) in adult (6–8 weeks old) wild-type cochleas is seen in olivocochlear fibers and their terminals in the inner spiral bundle under inner hair cells and under the three rows of outer hair cells (OHCs). Olivocochlear terminals also express VAT (green). B, Absence of M2 immunostaining in M2-null mice confirms the specificity of the antibody. Photomicrographs show the cochlear duct in the upper basal turn.
