Take LSD or psilocybin mushrooms and what enters the brain are chemical compounds that interact with neural ligand gates. The effect is a change in the perception of consciousness. Then if we load coarse grained brain states into a computer that ignores lots of fine grained detail, will that result in something different? Hell yeah! The idea one could set up a computer neural network, upload some data file from a brain scan and that this would be a completely conscious person is frankly absurd.
