From person-to-person and concept-to-concept our brains process information:

From person-to-person and concept-to-concept our brains process information "in much in a same way".

The eye gets visual data and codes data into electric neural action which is fed back to the cerebrum where it is "stored" and "coded". This data can be utilized by different parts of the cerebrum identifying with mental exercises, for example, memory, observation and consideration. The output (i.e. conduct) may be, for instance, to read what you can see on a printed page.
