How the Brain Processes Information
The brain processes information in two main ways:
Bottom Up (BU)
Top Down (TD)
systems analyze the details and use existing knowledge to reconstruct them into a recognizable "whole"-- to produce a behavioral response
systems take in details through the senses and relay them to the brain to form an initial perception
is the ability to make sense of the environment
is the deliberate choice to concentrate on a sensation

BU systems simultaneously relay multiple details such as color, depth, form and movement to the brain.
TD systems put the details together into a mental image.
