Stereausis processing of binaural time-delays

Prevalent models of binaural processing have postulated that sound position is estimated in the binaural nuclei by neural delay-lines and coincidence detectors that compensate for time differences between the two ears. The impetus for the alternative stereausis idea was the challenge posited by the lack of convincing anatomical evidence of delay-lines in mammalian species. The stereausis model proposed that accurate neural delay-lines are unnecessary if binaural coincidence detectors instead combined information from slightly mismatched positions (or frequencies) on the two cochleae, effectively exploiting the accurate “mechanical” delay-line inherent in the cochlear traveling wave. Such a scheme turns out to be analogous to the way stereo-depth perception is derived from spatial disparities.
