WebApr 3, 2024 · The remaining 5% are smaller diameter, unmyelinated type II afferent fibers that contact numerous outer hair cells (OHCs) as they spiral hundreds of microns towards the cochlear base 1,2. Neurons whose cell bodies lie in the spiral ganglion are strung along the bony core of the cochlea, and send fibers (axons) into the central nervous system (CNS). These bipolar neurons are the first neurons in the auditory system to fire an action potential, and supply all of the brain's auditory input. Their dendrites make synaptic contact with the base of hair cells, and their axons are bundled together to form the auditory portion of eighth cranial nerve. The number of neurons in the spira…
