Reading, face recognition, and navigation are supported by visuospatial computations in category-selective regions across ventral, lateral, dorsal visual streams. However, the nature of streams their development adolescence remain unknown. Using fMRI population receptive field (pRF) modeling adolescents adults, we estimate pRFs high-level cortex determine development. Results reveal that pRF location, size, coverage vary category, stream, hemisphere both adults. While location is mature adolescence, size continue to develop - increasing face-selective decreasing place-selective alongside similar category selectivity. These findings provide a timeline for differential functions suggest be optimized accommodate stream demands through adolescence.

Abstract The topographic organization of category-selective responses in human ventral occipitotemporal cortex (VOTC) and its relationship to regions subserving language functions is remarkably uniform across individuals. This arrangement thought result from the clustering neurons responding similar inputs, constrained by intrinsic architecture tuned experience. We examined malleability this individuals with unilateral resection VOTC during childhood for management drug-resistant epilepsy. In cross-sectional longitudinal functional imaging studies, we compared topography neural representations 17 a resection, ‘control patient’ outside VOTC, typically developing matched controls. demonstrated both adherence deviation standard uncovered fine-grained competitive dynamics between word- face-selectivity over time single, preserved VOTC. findings elucidate nature extent cortical plasticity highlight potential remodeling extrastriate function. Teaser After pediatric deviations constraints visual reflect plasticity.
