Consciousness, the awareness of one's self and one's immediate environment, is defined, in this paper, in terms of the information about this awareness that is contained in or being processed by the brain. This particular information content in the brain is extracted from the correlation functions of brain waves observed in EEG measurements at N points by determining an observation-based special time-dependent probability function, PN and Shannon's information theory formula. It is shown how PN provides information about awareness contained in the ensemble of brain waves. Consciousness is defined either directly by a formula, C, that depends on PN and represents the information contained in brain waves at time t, or its time derivate, D, that represents the rate at which this information is being processed. These measures are not localized; they do not depend on a single, immutable, hardwired detail of the brain but they do reflect subjective experiences, encoded by any one of a number of possible hardwired circuits. They are not clinical tools for measuring consciousness but rather represent ways to extract the information content of the brain from experimental measurements. Justifications, based on observational evidence, are given for the formulas presented.
