Dr. Sigmund Freud uses terms such as ‘preconscious’, ‘conscious’, and ‘unconscious’ without explaining the anatomical and physiological basis to describe the mental function. Consciousness has two components, 1. The Contents of Consciousness, and 2. The Capacity of Consciousness. Freud is concerned with only consciousness that is projected to the cortical areas of the brain and ignores as to how consciousness is composed by the Reticular Formation and other nuclei in the Brain Stem. Apart from being a neurological function, each living individual cell is conscious and is aware of the fact of its existence, it knows its internal condition and it reacts and responds to the conditions of its external environment.
