Abstract
Interaural level differences (ILDs) are important features for sound localization. Sound arrives at the ears with different sound pressure levels (SPLs) depending on the azimuth of the source. fMRI with seven ILD settings spanning ±18dB (higher SPL in left ear is positive) is used to examine a rat model of subcortical ILD processing. Results show the inferior colliculus and dorsal lateral lemniscus contralateral to the higher SPL ear respond with larger signal change. This asymmetry is not apparent in the cochlear nucleus and superior olivary complex. These findings demonstrate fMRI is an effective tool for examining subcortical ILD processing.
