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.)
Imagery is the use of figurative language to represent objects, actions and thoughts in a way that activates the physical senses of the reader (sight, smell, hearing, tactile and taste). It is what makes the reader involved in a story, by activating feelings he/she might know. It is what makes a story feel realistic.
Its function in literature is to create a graphic representation of a scene, with as much description as possible so the reader can paint a mental picture of what's going on.
So, that through the use of imagery meaning is created could mean that it is what gives a story depth and complexity, it is what makes a story similar to the real world.
I’m rlly confused about this question.
