Book Description
The early postnatal period is a crucial stage for hippocampal development. During this critical period, the neonatal hippocampus is highly sensitive to the detrimental consequences of adverse environmental factors. Extensive clinical and preclinical evidence has shown that traumatic events early in life have profound and persistent effects on hippocampal function and behavior. This research topic focuses on the acute and lasting effects of early-life stress on various developmental processes in the hippocampus, and aims to uncover the molecules that are responsible for early-life stress-programmed effects and underlie resilience or vulnerability to stress-related neuropsychiatric disorders later in life. We hope the articles in this research topic will provide novel insights and stimulate future studies on the mechanisms of early-life stress and brain development.

Book Description
Chronic early-life stress affects a majority of the world's children and is associated with deficits in hippocampus-dependent cognitive function during adulthood. Studies in humans cannot establish with certainty whether early-life stress causes cognitive dysfunction because other influences, including differences in genes and in environment, cannot be controlled. Therefore, we created a novel mouse model of chronic early-life stress to take advantage of the power of genetically modified mice to elucidate the molecular mechanisms and roles of specific genes responsible for the consequences of early-life stress on hippocampal function and dendritic structure. The chronic early-life stress paradigm involved altering the cage environment during the first week of life, which led to fragmentation of maternal care, in turn resulting in stress in the pups. Stress early in life was manifest in hormonal and molecular changes in the hypothalamus, and led to persistent impairment of hippocampus-dependent learning and memory in adult mice in the absence of anxiety-like or depression-like behaviors. Enrichment of the environment after the early-life stress period could not reverse the cognitive deficits provoked by the stress. Taking advantage of genetically engineered mice expressing yellow-fluorescent protein in hippocampal neurons, we examined the neuroanatomical basis of the cognitive defects provoked by stress. Whereas we did not confirm dendritic loss after early-life stress, we found that loss of dendritic spines, even in the absence of dendritic atrophy, was associated with profound memory defects in adult mice subjected to short, multi-modal stress. In summary, this dissertation developed mouse models for stress, and employed these models to study fundamental processes related to stress-provoked losses of hippocampus-dependent learning and memory throughout life.

Book Description
Stress Resilience: Molecular and Behavioral Aspects presents the first reference available on the full-breadth of cutting-edge research being carried out in this field. It includes a wide range of basic molecular knowledge on the potential associations between resilience phenomenon and biochemical balance, but also focuses on the molecular and cellular mechanisms underlying stress resilience. World-renowned experts provide chapters that cover everything from the neural circuits of resilience, the effects of early-life adversity, and the transgenerational inheritance of resilience. This unique and timely book will be a go-to resource for neuroscientists and biological psychiatrists who want to improve their understanding of the consequences of stress and on how some people are able to avoid it. Approaches resilience as a process rather than as a static trait Provides basic molecular knowledge on the potential associations between resilience phenomenon and biochemical balance Presents thorough coverage of both the genetic and environmental factors that contribute to resilience

Book Description
Development is a complex and highly dynamic process involving the cross talk among genes, maternal effects and environmental circumstances. Widespread evidence from plant to animal species show that variation in developmental conditions can modulate life history trajectories and influence key traits, such as growth, reproduction, and senescence. These effects are not limited to a single generation but can also be passed on future generations. This book aims to bring together studies of early life effects from the fields of evolutionary biology, global change biology, and biomedicine to synthesise and improve current knowledge of the mechanisms involved, and how variation in early life conditions translates into Darwinian fitness outcomes. Relying on examples of organisms’ responses to the ongoing and future environmental challenges of the Anthropocene, this book takes a novel approach to address the adaptive meaning of early life effects. The book has a broad scientific approach, targeting eco-evolutionary biologists, behavioural biologists, eco-physiologists, eco-toxicologists, as well as epidemiologists and biomedical scientists.

Book Description
Experiences during early life program the central nervous- and endocrine-systems with consequences for susceptibility to physical and mental disorders. These programming effects depend on genetic and epigenetic factors, and their outcome leads to an adaptive or maladaptive phenotype to a given later environmental context. This Research Topic focused on the hypothalamus-pituitary-adrenal (HPA)-axis and stress-related phenotypes, and on how HPA-axis programming by the environment precisely occurs. We included original research, mini-review and review papers on a broad range of topics related to HPA-axis programming.

Book Description
Epigenetic mechanisms (DNA modifications, histone alterations and non-coding RNAs) are crucial for transcriptional regulation and alterations of the “physiological epigenome” are increasingly associated with human diseases. During the last decade the emerging field of neuroepigenomics have started to impact tremendously in areas such learning and memory, addiction or neurodegeneration. This expert volume covers the role of epigenetic molecular mechanism in regulation of central nervous system’s function, one of the most exciting areas of contemporary molecular neuroscience. The book describes the current knowledge on the epigenetic basis of human disease covering the complete lifespan: from neurodevelopment/childhood (Rett Syndrome, Rubinstein-Taybi, autism), adolescence (eating disorders, drug addiction, anxiety), adulthood (depression, schizophrenia, amyotrophic lateral sclerosis, Huntington’s disease) and elderly (Alzheimer’s disease, Parkinson’s disease). The book also covers the three major players on neuroepigenomic mechanisms: histones alterations, DNA modifications and non-coding RNAs, their roles at the molecular and cellular level and the impact of their alterations on neuronal function and behavior. Finally, a special chapter on state-of-the-art technologies helps the reader not only to understand epigenetic driven changes in human cognition and diseases but also the methodology that will help to generate paradigm shifts on our understanding of brain function and the role of the neuroepigenome in human diseases.

Book Description
This entry in the Oxford Library of Psychology compiles cutting- edge research organized around the concept "molecular psychology," which applies principles of molecular biology to the study of behavior and its neural underpinnings. Determining the biological bases for behavior, and the extent to which we can observe and explain their neural underpinnings, requires a bold, broadly defined research methodology. The interdisciplinary entries in this handbook are organized around the principle of "molecular psychology," which unites cutting-edge research from such wide-ranging disciplines as clinical neuroscience and genetics, psychology, behavioral neuroscience, and neuroethology. For the first time in a single volume, leaders in diverse research areas use molecular approaches to investigate social behavior, psychopathology, emotion, cognition and stress in healthy volunteers, patient populations, and an array of non-human species including rodents, insects, fish, and non-human primates. Chapters draw on molecular methods covering candidate genes, genome-wide association studies, copy number variations, gene expression studies, and epigenetics while addressing the ethical, legal, and social issues to emerge from this new and exciting research approach.
