Even if we assume that all the parts are present and connected (not clear), surely having 90% reduced neural availability would lead to observable defects (e.g. psychosis, dissociative disorders/schizophrenia) if the neurons were directly responsible for consciousness. Yet this doesn't seem to be the case here (and in the other example someone else mentioned in this thread) which leads weight to the theories that treat consciousness as meta and emergent.
