Contralateral stimuli explain auditory brain activity better than ipsilateral ones
Evidence
Throughout all investigated regions, explanatory powers of sound levels or loudness estimates were higher for contralateral as compared to ipsilateral stimuli, albeit with varying degrees of lateralization across ROIs. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2610
