If the 'organ sacks' have a nervous system, they are sentient, even without a brain. The word 'sentient' might not be the right word, but then it becomes semantics. If they have a nervous system, they are human beings. Chop the head off a chicken, and the chicken will run around, still 'alive' even without its head. These experiments should stop, and the company should probably be shut down. If they don't stop or get shut down, what they are doing should be scrutinized with the same scrutiny as abortions.
