Lightmicroscopic Observations on Cochlear Development in Horseshoe Bats (Rhinolophus rouxi)

In horseshoe bats, the enhanced frequency selectivity within a narrow frequency range around the CF-component of the echolocation call is established in the cochlea (review: Neuweiler et al., 1980; Bruns, 1979; Vater, this volume). The frequency place maps of the inner ear of adult bats clearly demonstrate a correlation of the representation of the sharply tuned frequency range with the unusual thickness and width profile of the basilar membrane (BM) (Bruns, 1976, Vater et al., 1985), suggesting that the exceptional filter capacities of the auditory system are due to specialized hydromechanical mechanisms.
