What is consciousness?
The quantum holographic model described provides mathematically founded specifications in terms of physical laws for the nature of information, knowledge, qualia, intelligence, the self and consciousness. It explains how a brain/mind, its neurons, dendrites, synapses, etc may be postulated to work, so as to explain the well known binding problem. It sheds light on the fact that brains can be so much more versatile, competent, and efficient than their digital information processing counterparts, in relation to perception, cognition, language and intelligence. Further, it provides a methodology, by means of which to predict the information processing morphology and signal dynamics of such brains, i.e. their neuroinformatics on various scales, so as to be validatable against the experimental facts of neurophysiology, neuropsychology, etc. The paper begins with an explanation of general scientific principles and concepts associated with the model, and supporting evidence is described. It ends with a proposal by means of which it can be further experimentally validated. This proposal concerns predicting the existence and the properties of microtubules internal to the axon of the neuron. Such a prediction provides an independent confirmation of the long held, but still controversial hypothesis of Hameroff and Penrose, that such axonal microtubules are a quantum mechanism fundamental to consciousness in higher organisms, such as humans.
