Most people use three systems in the left side of the brain to help them read. These are called the temporoparietal system, the anterior system, and the ventral system. The temporoparietal system helps people remember what a written word means, the anterior system is in charge of identifying how word parts sound, and the ventral system lets people read easily.
However, with training in literacy skills, brain activity in children with reading disabilities can reach levels similar to those in non-impaired children.
