Approximately 50 years ago, newly generated neurons were discovered in the adult hippocampus of the rat brain. This discovery contradicted a key principle in mammalian developmental neurobiology - that all the neurons of the brain are made during early development - and led to intensive study to find out how new neurons are generated and how the process of neurogenesis is regulated. Since then, a unique population of adult neural stem cells has been identified, and many of the molecular pathways that control their self-renewal, proliferation, and cell fate have been elucidated. However, the presence of new neurons in the adult brain also poses intriguing functional questions that have, as yet, gone largely unanswered. Why is adult neurogenesis restricted to select brain regions? What functional benefit do these new cells confer? Indeed, the field of adult neurogenesis offers a unique opportunity to study naïve neurons as they mature, form connections with existing neural networks, and begin to participate in information processing. We review the basics of adult NSC biology and the maturation of newborn neurons. In particular, we focus on new neurons in the hippocampus, and how they contribute to function in this key memory-forming structure of the brain.

Neurogenesis in the adult brain has emerged as one of the most dynamic and rapidly moving fields in modern neuroscience research. The implications of adult neurogenesis for health and well-being are wide-ranging, with findings in this area having distinct relevance for treatment and rehabilitation in neurology and psychopathology. Adult Neurogenesis in the Hippocampus addresses these implications by providing an up-to-date account on how neurogenesis in the adult hippocampus contributes to critical psychological and physiological processes, such as learning and memory, and how it is modified by life experiences, such as aging, environmental enrichment, exercise, and dieting. The book also provides the most current reviews of how adult hippocampal neurogenesis influences the pathogenesis of mood disorders, addiction, and key neurological disorders. This book is the ideal resource for researchers and advanced graduates seeking focused knowledge on the role of adult neurogenesis in brain health and disease. Provides a unique overview of how adult hippocampal neurogenesis contributes to adaptive processes, brain psychopathology, and disease Includes state-of-the-art reviews by leading world experts in adult neurogenesis

The hippocampus is an important brain region, a true central hub for memory of various kinds and other processes. Neuropsychiatric disorders such as Alzheimer's disease, drug addiction, and schizophrenia are characterized by hippocampal alterations. The dentate gyrus of the hippocampus is a site exhibiting adult neurogenesis. This book covers the topic of the hippocampus from various perspectives. It discusses adult neurogenesis, effect of enriched environments on hippocampal plasticity, and long-term potentiation-associated gene expression. The book also addresses multiscale representations of complex environments and strategies in the hippocampus-dependent spatial tasks. Finally, insight into the hippocampus as a link between negative affect and relapse to psychostimulants is provided. The book collects evidence of various hippocampal functions in healthy and disordered brain.

Comprehensive Overview of Advances in Olfaction The common belief is that human smell perception is much reduced compared with other mammals, so that whatever abilities are uncovered and investigated in animal research would have little significance for humans. However, new evidence from a variety of sources indicates this traditional view is likely overly simplistic. The Neurobiology of Olfaction provides a thorough analysis of the state-of-the-science in olfactory knowledge and research, reflecting the growing interest in the field. Authors from some of the most respected laboratories in the world explore various aspects of olfaction, including genetics, behavior, olfactory systems, odorant receptors, odor coding, and cortical activity. Until recently, almost all animal research in olfaction was carried out on orthonasal olfaction (inhalation). It is only in recent years, especially in human flavor research, that evidence has begun to be obtained regarding the importance of retronasal olfaction (exhalation). These studies are beginning to demonstrate that retronasal smell plays a large role to play in human behavior. Highlighting common principles among various species – including humans, insects, Xenopus laevis (African frog), and Caenorhabditis elegans (nematodes) – this highly interdisciplinary book contains chapters about the most recent discoveries in odor coding from the olfactory epithelium to cortical centers. It also covers neurogenesis in the olfactory epithelium and olfactory bulb. Each subject-specific chapter is written by a top researcher in the field and provides an extensive list of reviews and original articles for students and scientists interested in further readings.

An engaging exploration of the scientific theories and medical conditions relating to stress and an examination of case studies that suggest ways to manage, reduce, and prevent stress in everyday life. Tension and anxiety are normal aspects of modern life, but ineffective stress management can lead to stress disorders, psychological distress, and physical ailments. An ideal resource for students researching the impact of stress on both physical and psychological health, this comprehensive two-volume set addresses scientific theories about stress, describes common symptoms and effects, identifies various sources of stress, explains how to identify and assess stress levels, and shares effective coping skills as well as strategies for preventing, managing, and reducing stress. More than two dozen contributors share their combined expertise, covering topics such as cognitive and behavioral theories and explanations of stress, the physical symptoms and effects of being subjected to stress, factors involving lifestyle and parenting styles, effective and ineffective coping methods, and finding support in mitigating stress. The set also supplies 20 personal accounts of stress, offers sidebars throughout its pages that present additional information about interesting related topics, and presents primary sources and statistics to encourage students to use their research and critical thinking skills.

The Handbook of the Psychology of Aging, Seventh Edition, provides a basic reference source on the behavioral processes of aging for researchers, graduate students, and professionals. It also provides perspectives on the behavioral science of aging for researchers and professionals from other disciplines. The book is organized into four parts. Part 1 reviews key methodological and analytical issues in aging research. It examines some of the major historical influences that might provide explanatory mechanisms for a better understanding of cohort and period differences in psychological aging processes. Part 2 includes chapters that discuss the basics and nuances of executive function; the history of the morphometric research on normal brain aging; and the neural changes that occur in the brain with aging. Part 3 deals with the social and health aspects of aging. It covers the beliefs that individuals have about how much they can control various outcomes in their life; the impact of stress on health and aging; and the interrelationships between health disparities, social class, and aging. Part 4 discusses the emotional aspects of aging; family caregiving; and mental disorders and legal capacities in older adults. Contains all the main areas of psychological gerontological research in one volume Entire section on neuroscience and aging Begins with a section on theory and methods Edited by one of the father of gerontology (Schaie) and contributors represent top scholars in gerontology

In the mid-sixties, the discovery by Altman and co-workers of neurogenesis in the adult brain changed the previous conception of the immutability of this organ during adulthood sustained among others by Cajal. This discovery was ignored up to eighty’s when Nottebohm demonstrated neurogenesis in birds. Subsequently, two main neurogenic zones were characterized: the subventricular zone of the lateral ventricle and the subgranular layer of the dentate gyrus. Half century later, the exact role of new neurons in the adult brain is not completely understand. This book is composed by a number of articles by leaders in the filed covering from an historic perspective to potential therapeutic opportunities.
