title: A comparison of synchronization filters in different auditory receptor organs.
abstract: Measurements of the frequency dependence of synchronization of cochlear nerve fibers obtained in different auditory receptor organs are compared. These synchronization filter-functions are lowpass filter-functions and differ primarily in corner frequencies which we estimate to be (in kHz): 2.5 (cat), 1.1 (guinea pig), 0.48 (alligator-lizard tectorial fibers), 0.42 (tree frog), and 0.34 (alligator-lizard free-standing fibers). Some of this variation in corner frequency can be explained by temperature-dependent lowpass-filter mechanisms with a temperature factor of 2.6-3.3 for a change in temperature of 10 degrees C. However, factors in addition to temperature must be involved in producing the differences in corner frequency between cat and guinea pig fibers and between tectorial and free-standing fibers in the alligator lizard.
