I am interested in cryogenics and I am trying to asses if certain essential neural information would be preserved after death and cryogenic freezing of a human brain. The particular essential neural information I am concerned here about is two kinds of info, specifically, the “neural weights” associated with each synapse and the “threshold values” associated with each neuron.
So my questions are:
How are the neural weights and the threshold values physically represented (in the form of chemicals or molecular/cellular machinery) when the neuron is not firing signals nor receiving signals?
Are there some known kinds of particular chemicals/receptors/molecules the concentration of which corresponds to the threshold value of each neuron or corresponds to the neural weights of each synapse? (so you can measure the exact magnitude of each threshold value or neural weight just by measuring the concentration of the corresponding chemicals/receptors/molecules)
And, if so, is that concentration maintained 10 minutes after death?
And, if so, is that concentration maintained if your brain is cryogenically frozen?
The obvious relevance of these above questions is that if such information is not physically represented after death then you would be just ripping yourself off to pay money to be cryogenically frozen since it would be logically impossible for that information to be restored in the future no matter how advance technology becomes even in a billion-billion-billion years time!!!
