Auditory areas are recruited for naturalistic visual meaning in early deaf people.

ABSTRACT: Congenital deafness enhances responses of auditory cortices to non-auditory tasks, yet the nature of the reorganization is not well understood. Here, naturalistic stimuli are used to induce neural synchrony across early deaf and hearing individuals. Participants watch a silent animated film in an intact version and three versions with gradually distorted meaning. Differences between groups are observed in higher-order auditory cortices in all stimuli, with no statistically significant effects in the primary auditory cortex. Comparison between levels of scrambling revealed a heterogeneity of function in secondary auditory areas. Both hemispheres show greater synchrony in the deaf than in the hearing participants for the intact movie and high-level variants. However, only the right hemispher
