There are few more powerful mirrors of the human brain’s astonishing ability to rearrange itself to learn a new intellectual function than the act of reading. Underlying the brain’s ability to learn reading lies its protean capacity to make new connections among structures and circuits originally devoted to other more basic brain processes that have enjoyed a longer existence in human evolution, such as vision and spoken language. We now know that groups of neurons create new connections and pathways among themselves every time we acquire a new skill.
