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.)
