The last 20 years have yielded an explosion of information from the still nascent field of social neuroscience. Studies devoted to identifying neural correlates of social cognitive and moral judgment processing have established subcortical and cortical regions that are integral for how we filter and interpret information pertinent to family and friends, our social in-group, and strangers and engage in everything from forming immediate impressions of them to judging their behavior with respect to complex moral norms. What is less clear is how neural regions involved in implicit and explicit cognitive processing, or those cognitive processes that occur almost instantaneously as opposed to those that are more controlled respectively, interact to bias perceptions and behavior. Even less is known about how genes (and their variants) critical for neural function and the structural integrity within neural regions may modulate neural interactions critical for social cognitive and moral judgment processing. Recent methodological advancements assessing how different neural regions functionally work together with others, and how different genetic variants integral for neural function alter behavior, are establishing a more comprehensive view of the implicit and explicit social brain. These advancements demonstrate that structures critical for implicit processing, e.g., the amygdala, reliably covary in their activity with structures integral for explicit processing, e.g., dorsolateral prefrontal cortex, early and often during the processing of social information of varying complexity and in different contexts. This suggests that interactions between these regions are necessary to successfully navigate and immediately adapt to one’s environment. In turn, genetic variants like those that comprise the brain-derived neurotrophic factor (BDNF) gene, oxytocin receptor gene, or serotonin transporter gene likely play an important role in modulating the interaction between and within neural regions integral for interpersonal trust, intergroup processes, person perception, theory of mind (i.e., inferring the thoughts and feelings of others), and moral judgment processing. The purpose of this Research Topic is to further our understanding of how subcortical and cortical neural regions that vary in their functional contributions to social behavior also depend upon genetic influences in shaping individuals’ perceptions, beliefs, attitudes, behaviors, and how information is attended to and encoded to influence future social behaviors. It is particularly important to demonstrate how these regions reliably interact as a function of processing speed (i.e., implicit or explicit) and/or context to predict behavior or performance. Demonstrating how different genetic factors in turn moderate this interaction, or how genetic factors alter a specific region’s interaction with other regions, is equally important. We therefore solicit original empirical work, review and opinion papers, and methodological papers that can promote our understanding of how interactions between neural regions underlying implicit and explicit processes influence social cognitive and moral judgment processing and are, in turn, modulated by genetic predispositions. This includes work that utilizes fMRI, EEG and psychophysiological methodologies, lesion samples, as well as developmental and computational approaches. This Research Topic could serve as an important step in the evolution of our understanding of the complexity of the social mind as well as illuminate the robust effects context has on the way the brain interacts with different stimuli at every level of cognitive processing.

Over the past century, we have made great strides in reducing rates of disease and enhancing people's general health. Public health measures such as sanitation, improved hygiene, and vaccines; reduced hazards in the workplace; new drugs and clinical procedures; and, more recently, a growing understanding of the human genome have each played a role in extending the duration and raising the quality of human life. But research conducted over the past few decades shows us that this progress, much of which was based on investigating one causative factor at a time—often, through a single discipline or by a narrow range of practitioners—can only go so far. Genes, Behavior, and the Social Environment examines a number of well-described gene-environment interactions, reviews the state of the science in researching such interactions, and recommends priorities not only for research itself but also for its workforce, resource, and infrastructural needs.

Genes, Brain Function, and Behavior offers a concise description of the nervous system that processes sensory input and initiates motor movements. It reviews how behaviors are defined and measured, and how experts decide when a behavior is perturbed and in need of treatment. Behavioral disorders that are clearly related to a defect in a specific gene are reviewed, and the challenges of understanding complex traits such as intelligence, autism and schizophrenia that involve numerous genes and environmental factors are explored. New methods of altering genes offer hope for treating or even preventing difficulties that arise in our genes. This book explains what genes are, what they do in the nervous system, and how this impacts both brain function and behavior. Presents essential background, facts, and terminology about genes, brain function, and behavior Builds clear explanations on this solid foundation while minimizing technical jargon Explores in depth several single-gene and chromosomal neurological disorders Derives lessons from these clear examples and highlights key lessons in boxes Examines the intricacies of complex traits that involve multiple genetic and environmental factors by applying lessons from simpler disorders Explains diagnosis and definition Includes a companion website with Powerpoint slides and images for each chapter for instructors and links to resources

Our Genes, Our Choices: How Genotype and Gene Interactions Affect Behavior, Second Edition explains how the complexity of human behavior, including concepts of free will, derives from a relatively small number of genes, which direct neurodevelopmental sequences. Are people free to make choices, or do genes determine behavior? Paradoxically, the answer to both questions is "yes," because of neurogenetic individuality, a new theory with profound implications. Here, author David Goldman uses judicial, political, medical, and ethical examples to illustrate that this lifelong process is guided by individual genotype, molecular and physiologic principles, as well as by randomness and environmental exposures, a combination of factors that we choose and do not choose. Written in an authoritative yet accessible style, the book includes practical descriptions of the function of DNA, discusses the scientific and historical bases of genethics, and introduces the topics of epigenetics and the predictive power of behavioral genetics. In the decade since the first edition published, knowledge of genetic influences on the neurogenetic underpinnings of behavior has been transformed by genomic technologies. Genome-Wide Association studies, for example, have revealed that hundreds of genes influence vulnerability to psychiatric disease and innate predisposition to risk-taking behaviors. This new edition has been thoroughly revised to focus on free will and its neurogenetic origins. In addition, the use of polygenic scores for behavioral prediction are discussed in-depth, reflecting the GWAS (Genome-Wide Association Study) revolution and combined use of genetic predictors in polygenic scores. Sections on epigenetics are also substantially expanded throughout, better defined, and tied to neuroplasticity and gene-environment interaction. Figures and illustrations have been added or improved throughout, and disease nosology and terminology has been updated. Updates on the previous edition which was the First Prize winner of the 2013 BMA Medical Book Award for Basic and Clinical Sciences Poses and resolves challenges to moral responsibility raised by modern genetics and neuroscience Analyzes the neurogenetic origins of human behavior and free will Features expanded sections on the neurogenetic basis of free will, polygenic risk scores, and epigenetic influence over behavior, as well as improved figures and updated terminology

The past decade has seen a rapid accumulation of knowledge on the behavioral characteristics of zebrafish, and increased investigation into the neurobiological basis of behavior using zebrafish. This simple vertebrate represents an ideal compromise between system complexity and practical simplicity, with its mammalian sequence homology, fecundity, and conveniently small size and transparent embryology. Behavioral and Neural Genetics of Zebrafish assembles state of the art methodologies and the most current concepts pertinent to the neurobehavioral genetics of zebrafish. Discussing its natural behavior, motor function, and learning and memory, it focuses on the fry and adult zebrafish and features a comprehensive account of modern genetic and neural methods adapted to or specifically developed for Danio rerio. Numerous examples of how these behavioral methods may be utilized for disease models using the zebrafish will be presented, as well as a section on bioinformatics and "big-data" related questions. Focusing on this excellent translational tool, this book examines a species with which investigators may model and analyze even such complex human diseases as those associated with brain dysfunction. Provides the most comprehensive snapshot of the fast-evolving zebrafish neurobehavior genetics field Describes description of behavioral, genetic, and neural methods and concepts and adult and larval zebrafish Features examples of zebrafish models of human central nervous system disorders Discusses bioinformatics questions pertinent to zebrafish neurobehavioral genetics

Books such as Richard Dawkins's The Selfish Gene have aroused fierce controversy by arguing for the powerful influence of genes on human behavior. But are we entirely at the mercy of our chromosomes? In Are We Hardwired?, scientists William R. Clark and Michael Grunstein say the answer is both yes--and no. The power and fascination of Are We Hardwired? lie in their explanation of that deceptively simple answer. Using eye-opening examples of genetically identical twins who, though raised in different families, have had remarkably parallel lives, the authors show that indeed roughly half of human behavior can be accounted for by DNA. But the picture is quite complicated. Clark and Grunstein take us on a tour of modern genetics and behavioral science, revealing that few elements of behavior depend upon a single gene; complexes of genes, often across chromosomes, drive most of our heredity-based actions. To illustrate this point, they examine the genetic basis, and quirks, of individual behavioral traits--including aggression, sexuality, mental function, eating disorders, alcoholism, and drug abuse. They show that genes and environment are not opposing forces; heredity shapes how we interpret our surroundings, which in turn changes the very structure of our brain. Clearly we are not simply puppets of either influence. Perhaps most interesting, the book suggests that the source of our ability to choose, to act unexpectedly, may lie in the chaos principle: the most minute differences during activation of a single neuron may lead to utterly unpredictable actions. This masterful account of the nature-nurture controversy--at once provocative and informative--answers some of our oldest questions in unexpected new ways
