The neurophysiological basis of consciousness is hotly debated in the neurobiological literature at present. The subject is often confused by imprecise terminology. One of the core issues is the definition of consciousness. According to one standard English dictionary (Webster, 1989), consciousness has three aspects, or meanings: awareness of one’s own existence, sensations, thoughts and surroundings in the past, present and future (for which we might use the term qualitative concsciousness); fully active mental faculties (quantitative consciousness), and voluntary activity. The present discussion, like most others, although often implicity, will be limited to the examination of consciousness as awareness. |
