Abstract
From the neuronal characteristic frequency (CF) and the innervation site in the organ of Corti a place-frequency map was established for characteristic frequencies between 7.2 and 61.8 kHz, corresponding to locations between 90% and 10% basilar membrane length (base = 0%, apex = 100%, mean length measured under the inner hair cells 5.13 mm). The relation between normalized distance from the base (d) and frequency (kHz) can be described by a simple logarithmic function: d(%) = 156.5 â 82.5 Ã log(f), with a slope of 1.25 mm/octave of frequency. The present map, recorded under physiological conditions, differs from earlier maps determined with different methods. The simple logarithmic place-frequency relation found in the mouse indicates that mice are acoustic generalists rather than specialists.
