The primary visual cortex (V1) in blindness is engaged a wide spectrum of tasks and sensory modalities, including audition, touch, language, memory. This widespread involvement raises questions regarding the constancy its role whether it might exhibit flexibility function over time, connecting to diverse network functions specific task demands. would suggest that reorganized V1 assumes like multiple-demand system regions. Alternatively, varying patterns plasticity blind may be attributed individual factors, with different individuals recruiting preferentially for functions. In support this, we recently showed functional connectivity (FC) varies greatly across individuals. But do these represent stable plasticity, or are they driven more by instantaneous changes, now inhabiting V1? Here, tested FC from time. We show two years, unique highly small sample repeatedly sampled congenitally Further, using multivoxel pattern analysis, demonstrate reorganization allow decoding participant identity. Together recent evidence substantial differences connectivity, this indicates there consistent blindness, which differ each individual. suggests variability could used seek neuromarkers sight rehabilitation assistive approaches.

Research on brain plasticity, particularly in the context of deafness, consistently emphasizes reorganization auditory cortex. However, a critical question arises: to what extent do all individuals with deafness show same level reorganization? To address this question, we examined individual differences functional connectivity (FC), specifically from deprived Our findings demonstrate remarkable differentiation between deriving absence shared experiences, resulting heightened FC variability among deaf individuals, compared more consistent hearing group. Notably, language regions becomes diverse across deafness. This does not stem delayed acquisition, as it is found native signers, who are exposed rich natural since birth. comparing diversity signers and were early development, that experience also impacts differences, although moderate extent. Overall, our research points out intricate interplay plasticity shedding light ways manifests individuals. It further joins blindness, showing affected by sensory experience. Finally, these highlight importance considering personalized rehabilitation for loss.
