The red shows the increase in organzied white matter in the language centers of the preschooler's brain. The blue in this image shows massive underdevelopment and disorganization of white matter in the same areas needed to support learning in school. Both images are from recent studies done by the Reading & Literacy Discovery Center of Cincinnati's Children's Hospital. Increasing and organizing white matter is critical to the brain's ability to communicate across its various parts, boosting its functionality and ability to learn. Experience thus "hardwires" those connections in the brain, Hutton said.
