I think its possible to contend that our physical body is sufficient in providing a framework for our human consciousness to emerge, but it may not be necessary in maintaining it.
Think of a stroke patient. Often stroke patients lose their memories / personality temporarily, but then regain it some time later. The injured portion of the brain heals in some respect, but the memories/neural functions of the injured area often move / reorganize to a different location in the brain (which is why sometimes a stroke patient can feel sensation in say their hand when someone touches their face).
I think this comes to show that our consciousness/memories/etc are not necessarily tied to a specific source of physical matter, as even the brain can reorganize the "coded" functions to different areas inside it.
