Sensory deprivation

There was a short story that I read recently, about a group of scientists who wanted to conduct an experiment. This experiment entailed fully depriving a man of all senses and nerves. This man was old and had nothing to lose, so he then volunteered for the experiment. The author at this point in the story is clearly trying to evoke emotion out of the reader by the weird details, but not only that, but provoking curiosity of the end results. The man laid there for a while at first, only being able to mumble words. The mumbles turned into screams, he listed off information that he would've never known, such as names of dead relatives of the scientists. This urged many of them to leave the study. At this point, the subject became extremely self destructive, biting chunks of his flesh out, in an attempt to feel. In his last moments, he whispered "I have seen God and He has abandoned us." After he said this he died with no explanation or reason. He just simply died. This story is clearly to entertain and to spook the reader.
