Everything that we "pay attention to" will get recorded into our
memory. This has been well demonstrated by various neuropsychological
In one test called the Recall Test, 15 cards with various images or
words are flashed, and than the subject is asked to recall the images
or words presented, regardless of their original order of presentation.
Only 6 or so on average is recalled. That does not mean that the memory
of all 15 cards are not stored in the brain.
In another test called the Recognition Test, the 15 cards are flashed
to the subject and then those cards are shuffled in with another set of
unseen 15 cards. The 30 cards then are flashed one by one and the
subject is asked to identify which cards he has already seen. On
average, 97% of the cards were correctly recognized, even when pausing
for over 20 minute delay after presenting the first 15 cards.
That shows that the brain is like a camcorder. Everything is stored
that we pay attention to. If everything would be stored, our brain
would certainly become full quite soon. So special filtering is needed
to filter out useful information to keep, and clean out the unuseful
ones so next Morning we wake up with a fresh clean mind. Dreaming could
have such a major purpose.
Supermemory techniques also demonstrate that everything gets recorded.
Techniques to access data are used by supermemory experts by building
up associative links to them.
Perhaps Schizophrenia is a result of an overloaded brain. When the
brain gets full, new memory gets written out of control onto areas
where useful memory is already stored. The stable neural network
becomes unstable as the wiring of neural networks will begin to deform
into unstable randomness, and neurons begin sending signals randomly,
resulting in hallucinative effects. That is my guess.
