Necessary conditions for consciousness

I've considered this possibility, but I keep running into the fact that
removing any part of the body doesn't seem to reduce ones consciousness.
They perceive the lack of the body part perhaps, and they may have an
emotional adjustment, but there is nothing to suggest there is a loss of
consciousness. In contrast, altering any part of the brain can produce a
marked loss or change of consciousness.
