    Hey fellas... I just took some Benadryl to help sleep - but alas, it isn't working, but it does have me thinking some pretty crazy ideas.(as I pretty much took a good amount more then the recomended dosage(DO NOT ATTEMPT)).

    I was thinking... What does it take for a human brain to survive? I'm sure it's the obvious things like Oxygen, Water, Nutrients, Calories, Tempature, and many other things. So hypothetically speaking. If you could give a brain all the things it needs to sustain it's self - would it be possible to basically have a brain in a jar? Could a brain therotically live without a body? Also, would it actually be possible in the next 10 years with our technology/medicine and understanding?

    Has anyone attempted it before? Anyone ever do a mind experiment on it?

    Weird question - I know... I would love your opinions and your ideas on how to make it work. I would love to shred my body one day and live in a milk jug. As long as it is whole milk ; )

    Myself, if I were surgically reduced to my primary neurophysiology and kept in a jar, would prefer to be suspended in a tequila solution. Herredura Blanco please. If a brain were kept alive apart from the body, it would most likely display an aberrant psychology do to the absence of hormones produced in certain myocardial and alimentary tract cells.


    I was some of the mud that got to sit up and look around.

    It is currently not possible to keep an isolated human brain alive. Perhaps in the future? Not 10 years. Perhaps 100?

    Experiments have been done, some decades back, in trying to keep an animal head alive, by pumping transfused blood through it. Those experiments were not particularly successful. The head stayed alive for a while, but it is probable that a lot of brain damage occurred, and in time the head died.

    Such experiments today would probably not get ethics committee approval. I am sure you can understand why!

    Apart from the purely physical and chemical ingredients required, a human brain needs mental stimulation, and communication with other people. It is highly probable that, if you kept a human brain technically alive as described, and isolated, it would rapidly go totally insane.

    I have seen this again and again on other sites, and I have to say it is a discouraging sign - some Gaelic sites have more or less given up because no one bothered to visit for Gaelic practice any more, due to all the t+tt++ requests etc. Others have a policy of filtering and altering the words t+tt++ and tr+nsl+tion (as I'm doing manually) to avoid being picked up by Google for these purposes.

    so you keep the brain in a cerebral fluid bath at 37 degrees, blood being pumpted around the body passing through a dialisis, an equivalent digestive system and an equivalent system for lungs (iron lung maybe?), connect the brain to electronic equipment for sensors, so far so good, but here are the problems
    1) cellular deterioration (probably solved with stem cells)
    2) damage to the blood leading to toxic effects (probably solved with artificial blood)
    3) regulating all the brain needs at the levels it needs (too much constant monitoring)
    4) knowledge of what the brain needs isn't exactly 100%, very hit and miss, so it would take a bit to figure out the exact method
