Medial olivocochlear inhibition is stronger apically and shifted half an octave
Evidence
The proposed MOC strategy is inspired by the contralateral MOCR but is not an accurate model of it. So far, we have disregarded that contralateral MOCR inhibition is probably stronger for apical than for basal cochlear regions (Lilaonitkul and Guinan 2009a ; Aguilar et al. 2013 ) and that there is a half-octave shift in frequency between the inhibited cochlear region and the spectrum of contralateral MOCR elicitor sound (Lilaonitkul and Guinan 2009b ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1981
