Thanks for looking into it. FYI, it seems like the time dimension won't be necessary since people have recovered after their brain activity stops e.g. Profound Hypothermia and Circulatory Arrest
I don't think you can conclude that "the time dimension won't be necessary" from the paper you linked.
(A) Because the brain temp in fig 1 (and many of the other experiments reported) was about 20 deg C, and neurons still fire at that temperature. (It's routine in many experiments to record synaptic activity in neurons at or near these temperatures). So you can't infer from the metabolic measures that neural firing has ceased. Neural firing patterns are almost certainly preserved to some substantial extent under the conditions in this paper (a...
To all my physicists in the house, will it ever be possible for a device to scan the contents of a human head at the molecular level (say, 5 x 5 x 5nm) while the subject is still alive? I don't have a physics background, so if you could also just point me to the materials I need to read to be able to answer the question, that would be wonderful as well.
The background: I want to live to see the far future and so I'm researching the feasibility of alternatives to cryonics that'll let people "back up" themselves at regular intervals rather than at the point of death. If this is even theoretically possible then I can direct my time and donations towards medical imaging researchers. If not then I'll continue to support cryonics and plastination research.
I'm looking forward to your responses!
