The effect of viewing speech on auditory speech processing is different in the left and right hemispheres (original) (raw)

This study investigates how viewing a speaker's articulatory movements influences auditory speech processing, examining potential differences between the left and right hemispheres. Using whole-head magnetoencephalography (MEG), the researchers measured the N100m response, a neural indicator of auditory processing, in both auditory-only (AO) and audio-visual (AV) conditions. Results indicate that visual speech cues significantly modulate the auditory cortex's response, with observable differences in the N100m amplitudes between hemispheres, suggesting lateralized effects of auditory-visual integration.
