The term information processing is used equally in information technology, psychology and the neurosciences to describe brain processes. In psychology, it refers to the operations by which people mentally manipulate what they learn and know about the world and information technology talks about information processing as the efforts to understand how we take in, process, access and store new information.

The brain’s purpose is to integrate information about the outside world together with information from inside the body. The purpose of this, as some have suggested, is to predict the future. To anticipate and engage with change in an adaptive way. Consciousness consists of monitor images of the inner and outer worlds; it can be seen as a container for the representation of all experiences.
