"In theory, a disembodied head could survive in suspended animation, staying alive with blood from the donor body but
incapable of controlling any bodily function—and in incredible pain, says Jerry Silver, a professor of neurosciences at Case Western Reserve University in Ohio who has spent his career seeking a cure for paralysis.
The head will have a “miserable existence,” where it won’t be able to breathe or control its own heart rate—a fate far worse than being a quadriplegic. The head’s windpipe would be attached to a respirator, so it could be ventilated, and it could remain alive like that for days."
