    If memories aren't encoded in the brain, then it's not necessary to relearn
    anything. The mind simply relies on different neurons to facilitate the
    recollection. If memories are indeed encoded in the brain, then once the
    relevant neural tissue is destroyed, they're not going to suddenly pop up in
    a different set of neurons.

    Why don't you look up memory in it, and see what it says?
