Unfortunately, there ARE some data bottlenecks which, if severed, have NEVER been shown to either grow back or be jury-rigged out of other components.

Agreed. Also another fascinating aspect of the brain particularly in Alzheimer's patients is their knack for recalling things from way back in their childhood as opposed to recent events is that synapses that forward and store events into the memory stop firing. I found this out by asking a doctor about this, because I was fascinated that my grandmother can clearly recall events from years and years ago. It even floors my father and his two sisters.

I have that "peculiarity" myself.
I can recall useless minutiae from 25 years ago yet forget that I have the stove on until smoke fills the house...:))

Also, I have to re-read some new thing I'm trying to learn several times before it "catches" in my brain.
Yet I can recall everything I learned pre-accident without effort.
