Rather than examining the brain and nervous system to see what they tell us about the mind, this book begins with an examination of conscious experience to see what it can tell us about the brain.

Through this analysis, the first and most obvious observation is that consciousness appears as a volumetric spatial void, containing colored objects and surfaces. This reveals that the representation in the brain takes the form of an explicit volumetric spatial model of external reality. The world we see around us therefore is not the real world itself, but merely a miniature virtual-reality replica of that world in an internal representation. In fact the phenomena of dreams and hallucinations clearly demonstrate the capacity of the brain to construct complete virtual worlds even in the absence of sensory input. Perception is therefore somewhat like a guided hallucination, based on sensory stimulation.

This insight allows us to examine the world of visual experience not as scientists exploring the external world, but as perceptual scientists examining a rich and complex internal representation. This unique approach to investigating mental function has implications in a wide variety of related fields, including the nature of language and abstract thought, motor control and behavior, as well as to the world of music, art, and dance, showing how the patterns of regularity and periodicity in space and time apparent in those aesthetic domains reflects the periodic basis set of theunderlying harmonic resonance representation in the brain.
