title: Acetylcholinesterase activity in the chinchilla organ of Corti in normal and acoustically overstimulated animals.
abstract: The distribution of acetylcholinesterase (AChE) positive nerve fibers and endings in the organ of Corti of normal and acoustically overstimulated chinchillas is described. The strongest activity was located in the inner spiral bundle, ane remained almost unchanged even after all the outer and the majority of the inner hair cells had degenerated as a result of intense exposure. In the chinchilla even the apical coil had three rows of AChE-positive nerve endings under the outer hair cells.
