Research in neuroscience is revolutionizing how we think about psychiatric diagnosis and treatment‎.‎ Psychiatric disorders reflect dysfunction of the human mind and involve changes in cognition‎,‎ emotion‎,‎ and motivation‎.‎ Understanding how the neural networks that underlie these mental functions become dysfunctional holds great promise for devising innovative approaches to diagnosis and treatment‎.‎ Scientific progress is being driven‎,‎ in part‎,‎ by advances in human functional neuroimaging‎,‎ which is being used to characterize the activity of specific brain circuits at rest and during the performance of specific tasks‎.‎ Moreover‎,‎ advances in clinical neuroscience are being coupled with expanding knowledge about genetics and cellular and synaptic neuroscience‎.‎ Taken together‎,‎ these advancements offer the hope of much more mechanism‎-based approaches to treatment in the future‎.‎ Better understanding of neural circuits also can provide the basis for innovative psychotherapeutic strategies that take advantage of brain plasticity for purposes of neurorehabilitation‎.‎In this book‎,‎ we examine recent developments in the field of network neuroscience and their potential impact on clinical psychiatry‎,‎ including the way that psychiatrists are trained and interact with other medical specialties and mental health professionals‎.‎
