>They know that MRIs can show different parts of the brain getting more or less blood flow I always wondered about this as a casual person with a heavy consumption rate of neuroscience. I fallen in to thinking of the "active" brain areas similar to lakes. places where activity seems to collect. if you remove the lake bed (fill it in? analogy breaks down here) then the activity will just collect itself in a different location. It might look / act a bit different from how it was before, but would still fit the profile overall - hence 'retraining' being possible. disclaimer: just personal thoughts, not backed by anything specific
