One thing to keep in mind is that your brain's hardware heavily influences your experience and thus your brain's development. Eg. whether you are male or female, tall or short, your limbs can make you run fast or not, your eyes can see well or not... all of these influence your experiences, your brain development, and who do you feel "you are". Try really removing all of your sensory inputs from your past, your body ability and disability, and do you think you end up the same person?
