Dear Nancy,
The description of whole brain reading I give is from Paul Dennison. I first heard him give this description at a Gathering. I believe he also gave it in the Whole Brain Reading course, now called Whole Brain Learning, when I took it years ago.
In whole brain reading the right eye scans across the page feeding information to the left hemisphere of the brain decoding the symbols on the page as letters and words, the left eye simultaneously scans across the page feeding information to the right hemisphere encoding the words into phrases giving them meaning, understanding, and comprehension.
I have worked with persons who relied mostly on the left hemisphere right eye for reading. Some of whom had reached high levels of technical reading ability, however, they would often need to reread information five to ten times before they could fully understand/remember (coprehend) what they read. They would often complain of stress and fatigue from reading. I usually use the X-Span balance which may or may not have included DLR in the learning menu in these cases, however I have seen good results from the Action Balance for Seeing. Remember the goal, pre and post activities are as important for setting the brain/sensory system up for change as the learning menu is to helping make that change. A few balances from the 101 course, along with appropriate homeplay, often made a huge difference in the participation of the right hemisphere/left eye allowing them to greatly improve their comprehension reducing the number of times they needed to read something and increasing their enjoyment of reading.
Best Wishes,
Dave Saunders
