I did not say that every person with severe brain injury shows full cognitive functioning, but there are cases. You can get started with reading Pribram or Eccles, for instance:

i'm quite aware of who eccles is. that does not change that we have no reason to think that full cognitive functioning is preserved in the face of dramatic alteration to the brain. sure, there's some degree of neural plasticity, and such decreases rapidly as one matures, but none of that suggests that the mind is anything other than the brain.
eccles data has been combed over by tons of people, and yet virtually no one comes up with the conclusion that eccles did, that the mind has some dualistic aspect in terms of substance. moreover, it is clear to anyone who has read his work on the mind-body issue that his views are the result of his religious beliefs. he already thought he knew the "answer" before he ever looked at what was going on, and that's a terrible way of getting things right.
that's bias. of course, none of that changes his incredible work in neurophysiology.
And you still didn't get my point. You keep saying brain = mind, which is a metaphysical bias.
I could argue the same way by saying I don't accept the reality of my ordinary state of consciousness, as it also just a case of neurons ,misfiring, which I was culturally conditioned to. Your point of view would necessitate some explanation as to how my non-physical mind can significantly alter my physical brain and moreover random generators as in the experiments of Dean Radin.
In other words you are requiring a commitment - which I completely support - that neither modern neuroscience nor philosophy satisfactorilly fulfilled.
i wasn't endorsing any particular view. i was saying that the stuff in the beginning of this thread was silliness, and the people putting it out there weren't even trained enough in the study of mind to recognize the kinds of issues that need to be addressed. in the same way that you don't even know what to look for when someone turns up ill if you have no medical training, you just don't even know what issues are pertinent, what must be addressed in order to get the rest of your argument off the ground, if you don't know jack about the subject.
that said, we have good reason to think that the mind is just the brain. such a theory has deep explanatory power and amazing predictive force. could that be wrong? sure. but we have no reason to think so at all. the fact that some experiments give strange results doesn't change that. in fact, you would have to have some very, very strong bias that the mind is something other than the brain in order to get that out of the experiments you're addressing. the fact is that we don't understand all the workings of the brain. that's why there is so much work being done on it right now, and the field is early in its infancy. but history has taught us that constantly looking for gaps in which to find Mystery (the capitalization is purposeful) fails us over and over. what we repeatedly find is that the Mysteries were, in fact, mere mysteries, and the explanation turns out to be physical in nature and not something spooky. since this has always been the case in the past it would seem sensible that, at some point, that would just become the default position. and yet...
we are so desperate to be special.
