Inside the brain, toward the back, we have an area known as the cerebellum (The portion of the brain in the back of the head between the cerebrum and the brain stem. It is primarily responsible for the coordination of movement and balance). This area of the brain has 10x20 more neurological connections that any other area of the brain. As we integrate movement into our learning -- learning happens. The learning gets loaded in with the direct assistance from body. It gets what we call "anchored in" and therefore can be easily recalled. There is much more information on the brain and how movement relates to learning in this site.
I have worked with over 20,000 students in classrooms across the east coast. I have trained thousands of adults, mostly teachers, principals, administrators, and parents about basic physiology of the brain and body and movements that help to integrate the two. I have spoken at a variety of gatherings ranging from Title1 Conferences* to Eric Jensen's Brain Expo in Chicago.
* Title I refers to the Elementary and Secondary Education Act of 1965 the goal of which was to improve the academic achievement of the disadvantaged).
I have a sliding scale so that all can participate. My basic fee for children is $55 and $65 for adults. The $55 fee for children includes a 45-60 minute session with a customized movement plan for the individual child. The $65 fee for adults includes the same. These prices are flexible according to income.
Brain Gym is certainly my base, but I have studied many other movement therapies that are connected to developmental reflexes that complement Brain Gym nicely. I often times will also look at the kind of nutrition that one is getting in order to evaluate the whole person.
Since God designed each of us as individuals this answer always varies. I can say through experience that the participants who practice their movement plan at home are the ones that notice the most progress. I always tell people that my job is to not to continue seeing you. If I have done my job, then you have learned enough on your own to not need me. Maintenance is a good idea but frequent visits over a long period of time are not recommended.
