"WebbType I SGNs represent 90-95% of the total SGN population and are thus responsible for the vast majority of hearing input. Each type I SGN extends one unbranched peripheral process, or “radial fiber,” which forms a single ribbon synapse with one IHC (Fig. 1). Each IHC is innervated by a total of 6-20 type I SGNs in the mature mouse cochlea [26]. " - Ribbon synapse hearing
