The Cooperative Neuron is part of a revolution that is occurring in the sciences of brain and mind. It explores the new field of cellular psychology, a field built upon the recent discovery that many neurons in the brain cooperate to seek agreement in deciding what's relevant in the current context. This cooperative context-sensitivity provides the cellular foundations for knowledge, doubt, imagination, self-development, and the search for purpose in life. This emerging field has far-reaching and fundamental implications for psychology, neuroscience, psychiatry, neurology, and the philosophy of mind. In a clear and accessible style, the book explains the neuroscience to psychologists, the psychology to neuroscientists, and both to philosophers, students of the behavioral and brain sciences, and to anyone intrigued by the enduring mystery of how brains can be minds.
