Fig. 5. Kv3.4 is expressed in choline acetyltransferase (ChAT)-positive cochlear efferent nerve fibers. Scale bar: 10 μm. (A) Kv3.4-positive radial fibers contacting OHCs are also positive for NKA and ChAT (2 cochlear preparations from 2 rats). (B) Kv3.4-positive spiral fibers near IHCs are ChAT-positive (C, 2 cochlear preparations from 2 rats) but NKA-negative (B, n=7 cochlear preparations from 7 rats). The relative anatomical regions corresponding to panel A- C are described in the diagram.
