Lesson 1White-matter pathways: arcuate fasciculus, uncinate fasciculus, superior longitudinal fasciculus — roles in repetition and integrationThis part breaks down main connecting fibre bundles like arcuate, uncinate, and top long ones, their layout, links, and jobs in repeating, word-meaning mixing, and front-back language paths.
