Reading and white matter in the brain

A new study that focuses on “white matter” finds that learning how to read relies on changes in brain connections.

The researchers found that high-performing readers initially had lower levels of white matter in the areas of the brain associated with reading, but these levels grew rapidly during the three years studied. By contrast, below-average readers had higher initial levels of white matter in the areas associated with reading, but these levels declined over time, suggesting the children were not creating and strengthening neural pathways.
