Fiber-tract differences in people with congenital and acquired blindness

Presentation

Abstract

Visual deficits can lead to differences in both the gray and white matter of the brain. Previous research has shown that there are connectivity differences (functional and structural) between sighted and blind individuals, with further differences in cortical activation between those with congenital and acquired blindness. The current study sought to determine the differences in major white matter tracts between congenitally blind and acquired blind participants, as well as to determine how they each differ from sighted subjects. Diffusion-weighted images were collected from three groups of
