I think it might be helpful in some forms of MI but very limited. No offense but this Dr Oz sounds like an idiot. To me the brain and the mind are two separate things and there isn't a very good understanding of either one or how they function together in a normal or abnormal way. Every vertebrate and most invertebrates has a brain but not necessarily much of a mind so it's a lot more complicated than just physiological tissue.
I hear what you're saying though.
