Discussion Overview

The discussion explores the hypothetical scenario of sustaining life in a human head detached from the body, focusing on the biological and ethical implications of such a situation. Participants consider the feasibility of using technology to maintain a head's functions and the associated moral questions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants question whether it is possible to sustain life in a head using machines that provide necessary inputs like blood and nervous system information.
  • Others argue that current technology does not allow for effective interfacing between a head and a machine, though they suggest that replicating bodily conditions might make it feasible.
  • One participant emphasizes that the brain controls vital functions and that a headless body would not survive long, raising concerns about medical ethics in keeping bodies alive without the possibility of revival.
  • Another participant asserts that brain death equates to death, implying that sustaining a head would not be viable.
  • Some participants reference cultural works, such as a classic sci-fi film and a short story, that explore similar themes, indicating a broader interest in the topic.
  • One participant introduces the idea of transferring thoughts to artificial circuits as a potential ethical consideration, questioning the morality of maintaining mental existence without a body.
  • A participant mentions the case of Walt Disney's head being preserved, linking the discussion to real-world examples of cryonics.

Areas of Agreement / Disagreement

Participants express a range of views, with no consensus on the feasibility or ethics of sustaining life in a detached head. Some agree on the challenges posed by current technology and medical ethics, while others explore speculative ideas without resolution.

Contextual Notes

Limitations include the lack of detailed exploration of the biological mechanisms required for sustaining a head and the ethical implications of such practices, which remain unresolved in the discussion.

This may be an absurd question partially due to the fact that I don't know a lot about biology. But is it possible to sustain life for a person who lost his head. What I mean, is a machine that pumps blood and supplies the head with everything it needs to keep surviving. From the top of my head, I can only thing of blood and information from the nervous system as being an input to the head from the body.
 
Biology news on Phys.org
I don't think with present technology we can interface a head to a machine. But if you duplicate the necessary conditions as provided by rest of the body, then I don't see why not.
 
The brain (medulla oblongata) controls blood pressure, respirations and heartbeat, for example. The headless body will not survive long.

Keeping bodies alive when there is absolutely no way to "wake them" violates medical ethics, anyway.
 
Brain-death means dead.
 
I think bassplayer is asking if a head can be kept alive, not the body.

There is an old scifi classic that played with this idea: The Brain That Wouldn't Die. Now public domain.

That movie scared the bejeesuz out of me when I was a kid. :biggrin:

Yes I did mean the head being alive and not the body. I realize its not possible but thought it would be interesting if someday it would be.
 
You may read Roald Dahl's classic short story on that theme..

Why?
I see absolutely nothing unethical (in principle) in maintaining an individual's mental existence beyond the duration of his or her body's existence (for example, transferring the thoughts etc onto artificial circuits, creating a soul-bank).

It MIGHT be unethical to demand of others to pay the upkeep of such machinery if the disembodied souls would not be able to provide services of various kinds to those others.
