Leonard Shlain Reading Quotations

When you read a book, you generate beta waves irrespective of the book's content. But if you look up from it, and start watching TV - it doesn't matter what the content of the program is - the beta waves disappear and you start processing alpha and theta waves. These are the same waves that you generate during meditation. Reading is primarily left hemisphere and watching television is primarily right hemisphere. Now how could that not have a major effect on our culture?
