Method Reveals Relationship Between White, Gray Matter

Published August 27, 2014 in Simons Foundation Autism Research Initiative

A new technique helps researchers trace the nerve fibers that connect brain regions by revealing how the fibers physically relate to curves and folds on the brains surface. The method was described in Medical Image Analysis. The technique examines the relationship between white matter, composed of nerve fibers and support cells, and gray matter, which is largely made of the cell bodies of the neurons the fibers sprout from. Preliminary findings support the theory that autism involves early, hyperconnected and dense brain growth before an abnormal decline, the researchers say.
