Psychology Major here! :) Hope this helps:
1) Up to date, there is still no definite answer when it comes the capacity of information a brain can withhold - it is truly unlimited.
2) The size of a brain varies between species and its capacity to retain information varies as well.
3) Humans have the most complex psychological process to understand, however, there are many other species who have incredible cognitive intelligence. (Such as dolphins, for example.)
4) When damage is done to a certain side of the brain and there is a need to remove the damaged area, there is a possibility that the undamaged parts of the brain can take over the same functions as the removed area. (Therefore, for example, the remaining part of your brain can still nearly function to a maximum capacity depending of the severity of damage... as well as area).
5) The brain named itself "brain".
(The brain controls you, but you control the brain.)
Mr. O'Brien and Winston are the principals starrings of the novel.
Textually O'Brien tells Winston: The first thing you must realize is that power is collective. The individual only has power in so far as he ceases to be an individual..alone...free.. the human being is always defeated.
That is the first thing from O'Brien to Winston.
