You might be interested by the book "Consciousness and the Brain" by Stanislas Dehaene. In it, Dehaene tries to define Consciousness, based on a series of reproducible experiments designed to discriminate between conscious and unconscious processes.

For example, he is able to show that our unconscious processes that are responsable for parsing text and numbers are able to assign conceptual meaning to words/numbers (ie "five" and "5" lead to the same meaning), before any conscious awareness.

Although my summary hardly does it justice (as I'm still half-way through reading it), I highly recommend Scott Alexender's book review on Astral Codex Ten[0], it gives an exhaustive overview of the book and the subjects it covers.
