Myelination of the early visual cortex depends on sensory experience during development

Abstract

The research on individuals born blind reveals how sensory experiences shape brain structure, particularly in the early visual cortex (EVC). Using advanced imaging techniques like multiple parameter mapping (MPM) and diffusion-weighted imaging (DWI), the study compares the myelo- and cytoarchitecture of congenitally blind and sighted individuals. It shows significant differences in key parameters such as relaxation rates, proton density, and diffusivities. These changes suggest that lack of visual input affects the iron and myelin content in the EVC, highlighting the critical role of sensory experience in brain development and circuit stabilization.
