tunnel of Corti

Instead of extending radially through the tunnel of Corti to outer hair cells, afferents appear to stall and extend in longitudinal directions as inner spiral bundles (Figs.

The tunnel of corti, which runs through the Organ of Corti, divides the OHCs and the inner hair cells (IHCs).

Specifically, the cochlear duct is shortened, the organ of Corti exhibits supernumerary outer hair cells, mirror image duplications of tunnel of Corti and inner hair cells, as well as ectopic expression of patches of vestibular-like hair cells in Kolliker's organ.
