This is not a joke. Is it by all accounts impossible to do this, supposing that an artificial heart with artificial blood transport systems (that provide oxygen and all needed nutrients) were used to keep the cells from dying. Also, assuming the brain was yours, what would it feel like to have no sensory input whatsoever? Would you feel alive and conscious? Would you be dreaming? Also, what would happen if you hooked up two brains together? How about a hundred brains? a thousand? via physical neural networks and synapses. Would the resultant organism think as one, or would its thoughts be chaotic and cluttered?
