[senco-forum] Brain Gym

I know this has been discussed before but....
Opinions please:

I've seen the Guardian Article of a couple of years ago-  
Is this really pseudo science and a lot of mumbo jumbo? 

More importantly does it work?

Is it OK for primary but not secondary?

Is it one of those band wagons that people jump on and works for a short
time?

If it is any good - Who should we get to carry out staff training?

Thanks in advance,
Chris
