Contralateral stimulation drives larger auditory cortex BOLD responses than ipsilateral

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. In all regions, linear loudness models yielded at least slightly better goodness-of-fits as compared to linear sound intensity models, although still being outmatched by quadratic fits with sound intensity in the majority of cortical ROIs. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2625
