How does blindness onset impact on the organization of cortical regions coding for the deprived and the remaining senses? We show that the coding of sound categories in the occipital cortex is enhanced and more stable within and across blind individuals when compared to sighted controls, while a reverse group difference is found in the temporal cortex. Importantly, occipital and temporal regions share a more similar representational structure in blind people, suggesting an interplay between the reorganization of occipital and temporal regions following visual deprivation. We suggest that early, and to some extent late blindness, induces network-level reorganization of the neurobiology of auditory categories by concomitantly increasing/decreasing the respective computational load of occipital/temporal regions. These results highlight the interactive nature of regional brain development in case of sensory deprivation.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
