The Binaural Pathway

The binaural (two ears) pathway works to process location information about sound sources. The superior olivary complex (SOC) is the first place in the pathway where neurons receive input from both ears. Two main nuclei comprise the SOC:

lateral superior olive (LSO) works at high-frequencies using sound amplitude differences
medial superior olive (MSO) works at low frequencies using time-delay differences
