Using concrete scientific methods, this work addresses practical and philosophical questions about how the mind and its content form in the brain. An eclectic range of mental phenomena including learning, language, and self-perception are addressed with an eye toward explaining them as manifestations of neural network processes. While this book will be of particular interest to students of many cognitive fields of study such as neuroscience, psychology, and neural networks, it is designed to be accessible for general readers, as it straightforwardly and creatively integrates many disciplines and discussions relating to mental processes. Highlighted are the neuronal properties and regularity that form the mental phenomena and serve their explanation.
