it would have to be uploaded as a 3d simulation copying the brain exactly and it's neural network as sarkus mentioned. only if it was a clone, could it be a limited fascimile or representative of a mind with the capacity to continue learning or forming new neural pathways but still limited. memories are also encoded from direct experience which is different than what a computer can do. a computer can't taste, touch, smell, or feel. it's never hugged a tree, for instance or knows the taste of red wine or the scent of a rose etc. it depends what you want a computer to understand or do (function). a computer brain inside a moving robot can learn from practical sensory input but never exactly in the way totally organic life does because it's a different type of lifeform. but then again, it may not need to in order to function or be useful anyways. a computer based mind would have strengths that we don't possess and weaknesses that are our strengths and vice versa.
