“Patients in persistent vegetative state – or PVS as it is called for short – seem to be awake because their eyes are open, yet they show no awareness or responsiveness to the outside world. They are conscious, some would say, but there is no content to their consciousness. They have become an empty shell, there is nobody at home. Yet recent research with functional brain scans shows this is not always the case. Some of these patients, despite being mute and unresponsive, seem to have some kind of activity going on in their brains, and some kind of awareness of the outside world. It is not, however, at all clear what it means. Are they in some kind of perpetual dream state? Are they in heaven, or in hell? Or just dimly aware, with only a fragment of consciousness of which they themselves”
