Saw this news article and just had to share here where I will give the most credit for my son becoming a bookworm!
http://blogs.discovermagazine.com/80beats/2012/10/10/how-the-brains-of-bookworms-compare-to-those-of-bibliophobes/" A new study that looked at the differences in the brain development between children with different reading abilities may help answer the question. "
"Reading depends on connections among several areas of the brain that process visual, auditory, and linguistic information."
"Reading depends on connections among several areas of the brain that process visual, auditory, and linguistic information. In particular, two bundles of nerves that connect key language areas in the brain have been shown to be associated with reading skills: the arcuate fasciculus, important for understanding the sound structure of words, and the inferior longitudinal fasciculus (ILF), which is important for seeing words. Researchers already knew that in better readers, these neuron bundles were fatter and better insulated. They wanted to know if the neurons of weaker readers simply started off with skinnier nerve bundles or if their neurons developed differently."
