Research shows brain connections improve with reading practice
Students who practice reading can strengthen their brains -- especially the white-matter connections essential to learning, according to research by scientists at the Center for Cognitive Brain Imaging at Carnegie Mellon University in Pittsburgh. Researchers scanned students' brains, then enrolled struggling readers in an intensive reading program. Researchers again scanned students' brains, this time after 100 hours of reading practice, and found the training improved "not just their reading ability, but the tissues in their brain."
