Written with the same clarity, directness, and humor that have made Simon LeVay one of the most popular lecturers at Harvard Medical School and at the University of California, San Diego, The Sexual Brain examines the biological roots of human sexual behavior. It puts forward the compelling case that the diversity of human sexual feelings and behavior can best be understood in terms of the development, structure, and function of the brain circuits that produce them. Discarding all preconceptions about the motivation and purpose of sexuality, LeVay discusses the scientific evidence bearing on such questions as why we are sexual animals, what the brain mechanisms are that produce sexual behavior, how these mechanisms differ between men and women and how these differences develop, and finally, what determines a person's sexual orientation: genes, prenatal events, family environment, or early sexual experiences? The Sexual Brain is broad in scope, covering evolutionary theory, molecular genetics, endocrinology, brain structure and function, cognitive psychology, and development. It is unified by LeVay's thesis that human sexual behavior, in all its diversity, is rooted in biological mechanisms that can be explored by laboratory science. The book does not shy away from the complexities of the field, but it can be readily appreciated and enjoyed by anyone with an intelligent interest in sex.
An evolutionary psychologist explains how present-day sexual and romantic behavior reflect two million years of hominid evolution.
Do biological factors, such as gonadal hormones, determine our sexual destiny after our genes are in place? Do they make men aggressive, or women nurturing? Do they cause boys and girls to play differently or to have different interests? Do they explain differences in sexual orientation within each sex group? Do they contribute to the preponderance of men in science or women at home? Scientists working from a psychosocial perspective would answer these questions differently than those working from a behavioral neuroscience or neuroendocrinological perspective. This book brings both of these perspectives to bear on the questions, tracing the factors that influence the brain, beginning with testosterone and other hormones during prenatal life, and continuing through changing life situations and experiences that can sculpt the brain and its activity, even in adulthood. This influence has important implications for understanding the social roles of men and women in society, the different educational and emotional issues that confront males and females, the legal rights of those whose sexual orientation or gender identity do not correspond to norms, and even standards of clinical care for people born with physical intersex conditions that make it difficult to classify a person as male or female at birth. This original and accessible book will be of interest to psychologists, neuroscientists, pediatricians, and educators, as well as the general public. It is also suitable for use in graduate and undergraduate courses on the psychology of gender or on hormones and behavior.
Looks at the biology of gender, including such topics as male and female brains, sex differences in emotions, sexual orientation, hormones, and social roles
Society tells us that sex is an act of self-expression, a personal choice for physical pleasure that can be summed up in the ubiquitous phrase: “hooking up". Millions of American teenagers and young adults are finding that the psychological baggage of such behavior is having a real and lasting impact on their lives. They are discovering that “hooking up” is the easy part, but “unhooking” from the bonds of a sexual relationship can have serious consequences. A practical look into new scientific research showing how sexual activity causes the release of brain chemicals, which then result in emotional bonding and a powerful desire to repeat the activity. This book will help parents and singles understand that “safe sex” isn't safe at all; that even if they are protected against STDs and pregnancy, they are still hurting themselves and their partner.
The knowledge that there are biological differences in the male and female brain has been taken for granted in the scientific community for years, yet it's kept so quiet as to seem like science's dirty little secret. This book boldly and responsibly ventures forth with these findings and their implications.
Jordan-Young has written a stunning book that demolishes most of the science associated with the dominant paradigm of the development of sex and gender identity, behavior, and orientation. The current paradigm, brain organization theory, proposes: "Because of early exposure to different sex hormones, males and females have different brains"; and these hormones also create "gay" and "straight" brains. Jordan-Young interviewed virtually every major researcher in the field and reviewed hundreds of published scientific papers. Her conclusion: "Brain organization theory is little more than an elaboration of longstanding folk tales about antagonistic male and female essences and how they connect to antagonistic male and female natures." She explains, in exquisite detail, the flaws in the underlying science, from experimental designs that make no statistical sense to "conceptually sloppy" definitions of male and female sexuality, contradictory results, and the social construction of normality. Her conclusion that the patterns we see are far more complicated than previously believed and due to a wider range of variables will shake up the research community and alter public perception.
This collection of foundational papers on sex differences in the brain traces the development of a much-invoked, fast-growing young field at the intersection of brain and behavior. The reader is introduced to the meaning and nature of sexual dimorphisms, the mechanisms and consequences of steroid hormone action, and the impact of the field on interpretations of sexuality and gender. Building on each other in point-counterpoint fashion, the papers tell a fascinating story of an emerging science working out its core assumptions. Experimental and theoretical papers, woven together by editor's introductions, open a window onto knowledge in the making and a vigorous debate between reductionist and pluralist interpreters. Five major sections include papers on conceptual and methodological background, central nervous system dimorphisms, mechanisms for creating dimorphisms, dimorphisms and cognition, and dimorphisms and identity. Each section builds from basic concepts to early experiments, from experimental models to humans, and from molecules to mind. Papers by such leading scholars as Arthur Arnold, Frank Beach, Anne Fausto-Sterling, Patricia Goldman-Rakic, Doreen Kimura, Simon LeVay, Bruce McEwen, Michael Merzenich, Bertram O'Malley, Geoffrey Raisman, and Dick Swaab, illustrate a rich blend of perspectives, approaches, methods, and findings. Sex and the Brain will show students how a scientific paper can be analyzed from many perspectives, and supply them with critical tools for judging a rapidly emerging science in a contentious area.
Sexual difference in the brain has long been one of the more intriguing research areas in the field of neuroscience. This thorough and comprehensive text uncovers and explains recent neurobiological and molecular biological studies in the field of neuroscience as they relate to the mechanisms underlying sexual differentiation of the brain. Attempts have been made to clarify sex differences in the human brain using noninvasive techniques such as magnetic resonance imaging. Sexual Differentiation of the Brain thoroughly examines these techniques and findings, providing an up-to-date, comprehensive overview written by leading researchers in the field. Just a few of the topics addressed include genetic contributions to the sexual differentiation of behavior; in-vitro studies of the effects of estrogen on estrogen receptor-transfected neuroblastoma cells; and the evolution of brain mechanisms controlling sexual behavior. Other topics include sexual differentiation of neural circuitry in the hypothalamus; structural sex differences in the mammalian brain; and sexual differentiation of cognitive functions in humans. With its revealing and informative chapters, as well as provocative treatment of the subject matter, Sexual Differentiation of the Brain helps shed new light on one of the most fascinating areas of brain research.
Pornography is powerful. Our contemporary culture as been pornified, and it shapes our assumptions about identity, sexuality, the value of women and the nature of relationships. Countless Christian men struggle with the addictive power of porn. But common spiritual approaches of more prayer and accountability groups are often of limited help. In this book neuroscientist and researcher William Struthers explains how pornography affects the male brain and what we can do about it. Because we are embodied beings, viewing pornography changes how the brain works, how we form memories and make attachments. By better understanding the biological realities of our sexual development, we can cultivate healthier sexual perspectives and interpersonal relationships. Struthers exposes false assumptions and casts a vision for a redeemed masculinity, showing how our sexual longings can actually propel us toward sanctification and holiness in our bodies. With insights for both married and single men alike, this book offers hope for freedom from pornography.
Using findings from the latest information in developmental psychology, neuroscience and education, this book debunks the assumed differences between male and female brain function and reveals the brain's remarkable plasticity and the influence of culture on identity. Reprint.
***A NEW YORK TIMES BESTELLER*** An essential exploration of why and how women’s sexuality works—based on groundbreaking research and brain science—that will radically transform your sex life into one filled with confidence and joy. Researchers have spent the last decade trying to develop a “pink pill” for women to function like Viagra does for men. So where is it? Well, for reasons this book makes crystal clear, that pill will never be the answer—but as a result of the research that’s gone into it, scientists in the last few years have learned more about how women’s sexuality works than we ever thought possible, and Come as You Are explains it all. The first lesson in this essential, transformative book by Dr. Emily Nagoski is that every woman has her own unique sexuality, like a fingerprint, and that women vary more than men in our anatomy, our sexual response mechanisms, and the way our bodies respond to the sexual world. So we never need to judge ourselves based on others’ experiences. Because women vary, and that’s normal. Second lesson: sex happens in a context. And all the complications of everyday life influence the context surrounding a woman’s arousal, desire, and orgasm. Cutting-edge research across multiple disciplines tells us that the most important factor for women in creating and sustaining a fulfilling sex life, is not what you do in bed or how you do it, but how you feel about it. Which means that stress, mood, trust, and body image are not peripheral factors in a woman’s sexual wellbeing; they are central to it. Once you understand these factors, and how to influence them, you can create for yourself better sex and more profound pleasure than you ever thought possible. And Emily Nagoski can prove it.
Addresses common questions on topics such as sexuality, peer pressure, and eating disorders
The Brave New World of Sex We've seen in less than a generation a swift revolution in human sexual behavior, attitude, and consequences so dramatic that some people are left in a state of stunned dismay and the public at large in aimless confusion. Much of the trend, if you can call a revolu tion a trend, is fueled by, or at least made possible by, technological innovations dating back to the middle of the twentieth century. The birth control pill opened the gate to promiscuity with little fear of pregnancy; marriage became an annoyance; divorce be came an opportunity; two working parents became a necessity; and teenage sex became nearly as socially acceptable as holding hands or going to the movies. The copulation explosion resulted in a spiraling epidemic of children giving birth to children, many of them on welfare. Girls seeking relief through abortions were sometimes forced to have their unwanted offspring despite the inevitability of some of them living in poverty and a desperate dead-end environment of squalor and crime. Some misguidedly wanted babies and ended up the same way. To top it all, discipline 2 A Sexual Odyssey became a lost art, leaving schools and neighborhoods infested with gun-toting, knife-wielding teenage delinquents-even in middle-class areas-who engaged in contests fo see who could get the most girls knocked up. The chaotic state of fornication, mating, and birthing may be a throwback to the past.
During the last years human sexuality has been the focus of interest and study by various disciplines. In this volume a multidisciplinary team of international experts discuss contemporary issues of human sexuality from updates on diagnosis to the management of various sexual dysfunctions. Reviews of the management of several female sexual dysfunctions, the impact of cancer on sexual functioning, the impact of trauma on sexual desire and function as well as the newest trends in sex therapy; androgen deprivation treatment of sexual behavior and autogynephilia are discussed in detail. Further, the complex interplay between the field of human sexuality and the Internet, psychological and cultural aspects of infertility are reviewed. A large amount of clinical material on topics rarely covered in other volumes will prove invaluable reading to clinicians from various disciplines such as psychiatry, psychology, urology, gynecology, sexology and sex therapy.
Have you ever done something you knew would make someone else happy, sad or angry? Have you ever bought a thoughtful gift for someone you love? Or realized someone was being sarcastic with you? Or enjoyed someone else's misfortune? These everyday events involve mind mapping, your brain's ability to create mental pictures of how someone else's mind works. Mind mapping underlies all aspects of daily life, from the best to the worst. You won't find an aspect of your life where mind mapping isn't involved-and you probably never heard about mind mapping before! Brain Talk offers what you need to know about mind mapping and the emerging brain science of interpersonal neurobiology (how interacting with other people affects your brain). Brain Talk is written for the general public in an easy-to-read style and establishes a personal relationship with you. It creates vivid pictures in your mind with attention-grabbling examples, and walks you into powerful new insights about yourself and the important people in your life. Reading Brain Talk can be a life-changing experience. * Part One explains mind mapping and increases your ability to "read" people and map their minds (and your own). It helps you know what they want, what they're feeling and thinking, and what they're likely to do. Part One also covers mind masking (shielding your mind from being mapped), lying and deception. Brain Talk revolutionizes your understandings of yourself, your spouse or romantic partner, and your children, parents, siblings, and coworkers. * Part Two explores the darker aspects of mind mapping, like traumatic mind mapping and antisocial empathy.Traumatic mind mapping occurs when mapping some else's mind leaves your brain/mind traumatized. Did you grow up in a troubled home with experiences that produced vivid "flashbulb memories" lingering in your mind? Do you have recurring thoughts about someone you're dealing with who does disturbing things? Brain Talk helps you understand subtle interpersonal trauma and reveals the short- and long-term negative impacts of traumatic mind mapping. * Part Three shows you how to repair the negative impacts of traumatic mind mapping and effectively handle the difficult people in your life. Brain Talk also details how to use mind mapping to create positive healthy interactions with those you love, and ends on an uplifting note. Brain Talk is based on Crucible(r) Neurobiological Therapy, developed through fifteen years of clinical research with highly troubled clients. Brain Talk is also a crossover book for therapists, educators, and avid readers of brain science. * Four Appendices contain the scientific research underlying the main text and offer in-depth discussions of important topics and treatment details (over 100 pages and 400 references). Brain Talk is available in three versions: paperback and TWO Kindle versions (Standard and Professional). Brain Talk Professional Edition offers the additional functionality of directly downloading FREE scientific brain research articles published online. Consider this electronic edition if you a mental health professional, academic, graduate student, or die-hard brain wonk.(Read about Brain Talk Pro here.) Brain Talk is written by the award-winning clinical psychologist, Dr. David Schnarch, renowned relationship expert and author of the international best-selling books, Passionate Marriage and Intimacy & Desire. He has a proven track record for creating innovative therapies, and making complex brain science understandable and useful to the general public. His ground-breaking professional contributions have received awards from the American Psychological Association, the American Assn. for Marriage and Family Therapy, and the American Assn. of Sex Educators, Counselors, and Therapists. He is Board Certified in Couple and Family Psychology (ABPP), and his textbook Constructing the Sexual Crucible is used by therapist training programs around the world.
Sexual orientation (homo- vs. heterosexuality) is one of many sex differences observed in humans. Sex differences can result from differential postnatal experiences (interaction with parents, environment) or from biological factors (hormones and genes) acting pre- or postnatally. The first option is often favored to explain sexual orientation although it is supported by little experimental evidence. In contrast, many sexually differentiated behaviors are organized during early life by an irreversible action of sex steroids. In particular, the preference for a male or female sex partner is largely determined in rodents by embryonic exposure to sex steroids. The early action of these steroids also seems to affect sexual orientation in humans. Indeed, clinical conditions associated with major endocrine changes during embryonic life often result in an increased incidence of homosexuality. Furthermore, multiple sexually differentiated behavioral, physiological, or even morphological traits that are known to be organized by prenatal steroids, at least in animals, are significantly different in homo- and heterosexual populations. Thus prenatal endocrine (or genetic) factors seem to influence significantly human sexual orientation even if a large fraction of the variance remains unexplained to date. The possible interaction between biological factors acting prenatally and postnatal social influences remains to be investigated.
From the author of the groundbreaking New York Times bestseller The Female Brain, here is the eagerly awaited follow-up book that demystifies the puzzling male brain. Dr. Louann Brizendine, the founder of the first clinic in the country to study gender differences in brain, behavior, and hormones, turns her attention to the male brain, showing how, through every phase of life, the "male reality" is fundamentally different from the female one. Exploring the latest breakthroughs in male psychology and neurology with her trademark accessibility and candor, she reveals that the male brain: *is a lean, mean, problem-solving machine. Faced with a personal problem, a man will use his analytical brain structures, not his emotional ones, to find a solution. *thrives under competition, instinctively plays rough and is obsessed with rank and hierarchy. *has an area for sexual pursuit that is 2.5 times larger than the female brain, consuming him with sexual fantasies about female body parts. *experiences such a massive increase in testosterone at puberty that he perceive others' faces to be more aggressive. The Male Brain finally overturns the stereotypes. Impeccably researched and at the cutting edge of scientific knowledge, this is a book that every man, and especially every woman bedeviled by a man, will need to own. Praise for The Female Brain: "Louann Brizendine has done a great favor for every man who wants to understand the puzzling women in his life. A breezy and enlightening guide to women and a must-read for men." —Daniel Goleman, author of Emotional Intelligence From the Hardcover edition.
