Hi Paul,
I've just noted your query about 'where does this leave brain gym'?
There is a very interesting section on Brain Gym in the Bad Science book by Ben Goldacre. You can get it through our online bookshop
braininbusiness.com/content/view/32/54/
My view is that many things have a genuinely scientific basis or background that gets quickly distorted and misapplied. and then these things gain a life of their own that can grow and grow if there are enough people like the idea - there's often just enough science in the background to lend an air of credibility.
Ben Goldacre gets very hot under the collar about all sorts of pseudoscience which is why I'm looking forward to having a scientist at the Brain Friendly Learning Group so we can ask questions and get credible answers.
see you soon.
