I must decide whether to pull the plug. Not true! Not only have you lost all the upper brain functions that create your memories and behaviors and allow you to think and talk, but you have also lost all the involuntary stuff your lower brain does to keep you alive, like controlling your heart, respiration, nervous system, temperature and reflexes.

If you are brain-dead, these functions are being performed by hospital equipment like ventilators and catheters. You cannot recover from brain death. If you are in a coma, on the other hand, you are legally very much alive. In a coma, you still have brain function, which doctors can measure by observing electrical activity and your reactions to external stimuli. In other words, your body continues to breathe, your heart beats, etc.

Even better, you can, potentially, recover from a coma and regain consciousness. We now have a whole battery of scientific tests to confirm that someone is really, truly brain-dead. Okay, but what if I fall into a deep, deep coma? Will someone eventually pull the plug and send me off to the mortuary? Will I be trapped in both a casket and in the prison of my mind?

In the 19th century, master story teller Edgar Allen Poe exploited human fears in his stories, and the fear of being buried alive was no exception. He makes friends promise that they will not bury him prematurely, does not stray from his home, and builds a tomb with equipment allowing him to signal for help in case he should be buried alive only to wake from one of his episodes.

There were arrangements also for the free admission of air and light, and convenient receptacles for food and water, within immediate reach of the coffin intended for my reception. This coffin was warmly and softly padded, and was provided with a lid, fashioned upon the principle of the vault-door, with the addition of springs so contrived that the feeblest movement of the body would be sufficient to set it at liberty. Besides all this, there was suspended from the roof of the tomb, a large bell, the rope of which, it was designed, should extend through a hole in the coffin, and so be fastened to one of the hands of the corpse.

Unfortunately, the character takes all of these precautions only to find that his greatest fear is realized. It is not clear if Poe inspired innovation or if he was merely tapping into the feelings of the time, but this fear led to one of the creepiest categories of invention—coffin alarms. There were a series of inventions in the 19th century, which would aid someone, who was buried alive, to escape, breathe and signal for help. The tomb is equipped with a number of features including an air inlet F , a ladder H and a bell I so that the person, upon waking, could save himself.

The device has both a means for indicating movement as well as a way of getting fresh air into the coffin. Once sufficient time has passed to assure that the person is dead, the device can be removed.

In this instance, motion of the body triggers a clockwork-driven fan Fig. The device also includes a battery-powered alarm M. There is also a spring-loaded rod I , which will raise up carrying feathers or other signals.

As medicine has advanced, there have, of course, been technological advances in determining if someone is alive or dead.
