Lateralization weakens up the auditory pathway as interhemispheric connections dominate

Evidence

However, in the present study, the degree of lateralization differed considerably between regions, being particularly pronounced in the IC of the brain stem and rather weak in the posteromedial and anterolateral sections of HG. In fact, in stark contrast to the IC, changes in sound intensity were highly predictive of signal changes in HGpm irrespective of the ear of entry, pointing towards strong interhemispheric connections in the upper stages of the auditory system. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2610
