Curiosity : #1) In what form does the memory store in our brain? Can we restart the brain and take that information from a dead body?

It's been 4 months I have not posted anything. Well due to my studies I am unable to find time to interact in this beautiful community. But by now I will try to write even a post in a week.

I have started a new series in my blog as ' Curiosity'. Here I will write and describe some questions that you may eager to know about. Thus the name runs. Suitable name as per my intention right? Okay let's see what we got today...

MEMORY! This six letter word holds tons of moments, names, places etc. We don't have an identity without memory. So let's hope that our memory remains alive till we survive!
So how does the memory store in our brain?

Researchers have been able to trace that memories are stored throughout many brain structures in the connections between neurons, and can even depend on a single molecule for their long-term stability. Encoding is the first step in creating a memory. It's a biological phenomenon, rooted in the senses, that begins with perception. Separate sensations from visual system, auditory system, olfactory system and touch system travel to the part of the brain called the hippocampus, which integrates various perceptions as they occur, into one single experience. The hippocampus, along with another part of the brain called the frontal cortex, is responsible for analysing these various sensory inputs and deciding if they are worth remembering. If they are, they may become part of your long-term memory and these various bits of information are then stored in different parts of the brain.

Although a memory begins with perception, it is encoded and stored using the language of electricity and chemicals. The brain can be restarted immediately after death depending on the extent to which brain damage has occured. The process of cell death including the brain begins as soon as the heart stops beating due to the effects of lack of oxygen and continues for sometime until eventually all the remnants of the cells also disintegrate. Evidence has shown that if the heart can be restarted after the criteria for death have been met; then, an individual can be brought back to life and the human mind and consiousness can remain intact. Recent studies of near death experiences during an objective period of clinical death (in other words cardiac arrest) have also demonstrated that at least 10-20% of people who have undergone a period of reversible death will have some cognitive memories from that period and a smaller proportion of them will have clear recollections of exactly what was going on and what had been happening to them during cardiac arrest and death. This raises the fascinating prospect that the human mind and consiousness may continue for a period of time after we have reached the point of death.

It is 99.99% impossible to obtain the information from the brain of a dead body. Each person's brain stores data encoded uniquely for that individual. Even if we could read what neurons have stored we still could not decode the connections in a dead brain. To reconstruct memories, it would be necessary to 3d-scan a person's cerebral cortex precisely enough to work out the connectivity structures i.e make a list of which neurons-pairs are syneptically connected to each each other and estimate the strength of each connection. The data could then be used to run a computer simulation of the person's brain, not by any means perfect but probably good enough to reconstruct memories with usable fidelity. Currentlh we can not even do this for the simplest worm- brains, but all of the necessary technologies are improving fast, and there is a decent chance that we will be able to do such things within fifty years.
