This book is unique in expanding the boundaries of neuroscience, while remaining solidly grounded within it. In this, it outlines a new plateau of wider integrative understanding both within and beyond neuroscience. The book advances the view and implications of an integrated functional unity of consciousness and brain, inclusive of freedom of will. It reaches from first principles of human awareness and apprehension and the physical foundations of consciousness, through a structured integrative view of consciousness and the brain, to outlines of the ambient contextual influences of human living. Comprehensive overviews of brain theory and theoretical neuroscience are given. Fundamental brain functions of human apprehension, language, value, aesthetics, rational and extrarational knowing, biological primals, and adaptive integrations are seen to operate within such ambient influences as whole of nature, human plight, circumstances, personal life, good and evil, inner depths, worlds of man, and enlightenments.Prof Ronald MacGregor has published extensively in theoretical neuroscience since 1965, consistently advocating the foundationality of physiology and physical law in brain-mind function. His work has helped ground neuroelectric signaling within physical science and characterize the neuroelectric patterns of neurons and neural networks.
