Getting a new perspective on how the brain works and inspire a new way to design in computer science and engineering Unique book is the first of its kind to introduce basic human memory and cognition in terms of physical circuits, beginning with the possibility of ferroelectric behavior of nerve membrane, move to the logical nature of the nerve pulse is recognized as a soliton, and finally explore the architecture of cognition itself. This encourages discovery through methodical research brain theory, including reversible electric neurons, neural networks, associative memory systems in the brain, nervous state machine in associative memory, and reversible computers in general. Writing of circuits and systems perspective, the author reaches the specific disciplines, including neuroscience, psychology, and physics to achieve the rare coverage of: Nerve membrane Neural pulse and nerve memory Circuits and systems to memorize and recall Dendritic processing and human learning Learning in artificial neural networks Reversibility of the asset of human and machine Electrically reversible nanoprocessors Reversible arithmetic Hamilton circuit seekers Quantum versus classical Each chapter introduces and develops new materials and ends with exercises for readers to put their skills into practice.
