I will lock Neo into a bed and chain his arms, legs, torso, and neck down. Then I tape his eyes shut and tape headphones to his ears, so he sees no light and hears no sound. Then I leave him in this extreme isolation occasionally bringing him food and water. After three days, hallucinations occur of both visual and auditory as his brain struggles to cope with the complete lack of stimulus. Eventually, with zero stimuli the brain will begin to make up entire worlds of pure fear and pain to keep itself alive. But some part of his brain will stay sane, a little part hiding in the shadows. Only then will I take pity and stop giving food to him so he has weeks left to live without food and the extreme aches of hunger set-in as his body basically consumes itself to stay alive.
