I am interested in learning about the feasibility of keeping a human brain alive outside of a human body.

The question: What obstacles do we need to overcome to be able to keep a human brain alive outside of a human body?

The problems I am taking into consideration are:

  • connecting nerves with an artificial skeleton, (no need to connect spinal cord?)
  • delivering signals to the brain to avoid sensory deprivation?,
  • keeping brain in a "healthy state" as long as possible,
  • augmenting and stimulating brain,
  • connecting the brain to external devices without hurting it,
  • maintaining blood supply,blood transfusion problems (allergic reactions and hives, fever, hemolytic reactions, iron overload etc.)
  • can a brain be in a sleep mode? keeping brain in a "work" mode,
  • can a brain function without hormones?,
  • can we copy a brain?,
  • can we grow a brain? part of a brain?,
  • regenerating brain, slowing down the process of brain degeneration,
  • does the brain need bone marrow to properly function,
  • maintaining cerebrospinal fluid supply.

I asked this question on Quora, https://www.quora.com/What-must-be-the-conditions-to-keep-a-brain-alive-outside-of-a-body

  • $\begingroup$ What the dangers (with explanations) related to keeping a human brain alive outside of a human body. I want to understand them better. What are the reasons that we still cannot make a human brain live outside of a human body? I want a "big" answer. $\endgroup$
