Fear Extinction

Using the most well-studied behavioral analyses of animal subjects to promote a better understanding of the effects of disease and the effects of new therapeutic treatments on human cognition, Methods of Behavior Analysis in Neuroscience provides a reference manual for molecular and cellular research scientists in both academia and the pharmaceutic

This book aims to provide the reader a neuroscientific understanding surrounding a very simple question: how do we learn not to fear? Exploring answers to this question is very important for two reasons. First, learning about the neural mechanisms of fear extinction is of relevance to everyone’s life - it is such a basic yet relevant question to our daily experiences. Therefore, understanding brain mechanisms of fear and its regulation is essential from a basic neuroscience point of view. Second, excessive fear and the inability to regulate its expression is one of the hallmarks of fear-, anxiety-, trauma-, and stressor-related psychopathologies. And as such, learning about how fear is acquired, stored, expressed, and regulated could help advance our understanding of the etiology of psychopathology, the maintenance of symptoms pertaining to failure to regulate fear, and could help us develop novel therapeutics to equip providers and patients with the tools to better quell their fears. The contributions contained in this book are provided by experts in the fields of basic and clinical neuroscience, experimental and clinical psychology, and neuropsychiatry. The contributions are organized to start the reader with basic definitions of how we define fear, how we study its neural circuits at the molecular and cellular levels, how to study human behavior and the brain using state-of-the art experimental and statistical tools, to how much fear contributes to psychopathology. This volume ends with current advances aimed to enhance the capacity to extinguish fear; a clinical result that would aid in the treatment of multiple psychiatric disorders, followed by a discussion on future directions of this highly important and relevant field.

Throughout their lifetime, animals learn to associate stimuli with their consequences. Following memory acquisition and consolidation, circumstances may arise that necessitate that initially learned behaviour is no longer relevant. The ensuing process is called extinction learning and involves a novel and complex learning procedure that involves a large number of neural entities. While the neural fundaments of the initial acquisition are well studied, our understanding of the behavioural and neural basis of extinction is still limited and derives mostly from rodent data acquired through fear conditioning paradigms. Fear conditioning and extinction in rodents is a spectacularly successful paradigm within behavioral neuroscience. However, in recent years, new approaches have been emerging that examine the mechanisms of extinction learning in different setting that also involve appetitive models, a broader comparative perspective, a focus on other brain systems, an examination of hormonal factors, and conditioning of immune responses. Only a broader analysis of the neural fundaments of extinction learning will finally uncover shared and distinct mechanisms that underlie extinction learning in different functional systems. The papers compiled in this Research Topic offer new and valuable insights into the mechanisms and functional implementation of extinction learning at its different levels of complexity, and form the basis for new concepts and research ideas in this field.

Despite considerable progress in clinical and basic neurosciences, the cure of psychiatric disorders is still remote, little is known about their prevention, and the etiology and molecular mechanisms of mental disorders are still obscure. Diagnoses are still guided by patients' stories. The mission of animal models is to bridge the gap between `the story and the synapse.' Contemporary Issues in Modeling of Psychopathology attempts to do this by examining such questions as `What good might come from such a model? Are we wasting our time? How far can we carry results from model animals, such as rats and mice, without causing a highly distorted view of the field and its goals?' This book serves as the opening volume for a new series, Neurobiological Foundation of Aberrant Behaviors.

There are few clinical problems in the sleep medicine field that are more challenging than the sleep difficulties experienced by individuals suffering from post-traumatic stress disorder (PTSD). This book offers a unique, complete resource addressing all the basic concepts and clinical applications in sleep medicine in settings where combat-related PTSD is commonplace. Authored by leading international experts in the field of sleep/military medicine, Sleep and Combat-Related Post Traumatic Stress Disorder is organized in six sections and provides a broad perspective of the field, from the established theories to the most recent developments in research, including the latest neuroscientific perspectives surrounding sleep and PTSD. The result is a full assessment of sleep in relation to combat-related PTSD and a gold standard volume that is the first of its kind. This comprehensive title will be of great interest to a wide range of clinicians -- from academics and clinicians working within or in partnership with the military health care system to veteran hospital physicians and all health personnel who work with war veterans.

"The goal of this volume is to bring together the most recent empirical and theoretical developments in the basic science of fear learning and to translate these developments to the clinical understanding and treatment of fears and phobias. A major impetus for the volume was the recognition that basic science in fear learning is advancing far more rapidly than the clinical application of this knowledge. The book is structured to cover three main areas. The first presents the history of fear learning theory and fear measurement. The second area examines the acquisition and maintenance of fear, including neural circuitry, associative pathways, and cognitive mechanisms; the role of avoidance; and individual differences in fear learning. The third area covers the extinction, renewal, and reinstatement of fear, including neural circuitry and context dependency. The volume developed out of the Special Interest Meeting on Fear and Learning in Lignely, Belgium (May 2003), sponsored by the Fund for Scientific Research in Flanders, Belgium, and inspired by Paul Eelen. This volume is intended for both basic scientists and clinical scientists at undergraduate, graduate, and more advanced levels, as well as practicing clinicians who are interested in gaining an in-depth understanding of learning theory as it applies to fear and anxiety"--Preface.
