Focal electrical stimulation of dorsal nucleus of the lateral lemniscus modulates auditory response properties of inferior collicular neurons in the albino mouse.

abstract：:The number, size and distribution of myelinated nerve fibers were analyzed in the osseous spiral lamina (OSL) of young and old gerbils raised in a quiet environment. Because decreased endocochlear potentials (EPs) play a significant role in age-related hearing loss in the gerbil, we correlated morphometric and topogra...
