To expand on my holographic brain post, I have a friend who had some brain tissue removed about the size of a large navel orange because the feedback loops of information would sometimes cause a short circuit leading to seizures.
The brain tissue removal did not seem to have any effect on memory or all the intricacies and nuances of her solo violinist abilities.
The information of her brain was stored virtually uniformally everywhere in her neural network.

You can contrast this to removing a portion of a computer's hard drive.

The signals of living brains are not merely electrical but chemical, earth attuned as well as cosmic. It has a foot in the quantum level as well as mega systems that we do not yet understand or even recognize.

I suspect that the limbic system, the fluid filled "empty areas" of the brain, is one of the least understood structures of the mind.
It has been called the shock absorber of the brain.
I see it as a super chemical highway, antenna, and one of the more cosmicly attuned areas of the brain.

Typically my contributions here have little detailed scientific empirical data on the mechanical electric functions of a single tree because I am attuned to seeing the forest. Seeing the forest is a valuable contribution too.
