“I have quickly found that training my brain [with Nintendo’s Dr Kawashima’s Brain Training computer game] is a great way to keep my mind feeling young.” Nicole Kidman, actress

“There is no conclusive evidence showing that the continued use of these devices is linked to any measurable and general improvements in cognition. Practice at any task should lead to some form of improvement for that specific task.” Dr Jason Braithwaite, cognitive neuroscientist

Hmm, doesn’t practice make perfect? I remember practiceing my times table over and over again until I got them.  By doing that did I improve my brain? According to Dr. Jason I didn’t, but I am not doctor so I guess I don’t know.
