The brain processing for reading is different from listening (e.g., listening to an audiobook creates a different set of memories compared to reading a book). The right hemisphere is not as active in reading. Listening triggered increased activity in the left part triangularis (a component of Broca‚Äôs area). (Restak, Richard, MD. The New Brain. 181-182. PA: Rodale, 2003.)

Both left and right hemispheres and the prefrontal systems are used in the brains of good readers. (Healy, Jane M., PhD. Endangered Minds. p 215-218. NY: Simon & Schuster, 1990.)
