Book Description
The brains of males and females, men and women, are different, that is a fact. What is debated is how different and how important are those differences. Sex differences in the brain are determined by genetics, hormones, and experience, which in humans includes culture, society, and parental and peer expectations. The importance of nonbiological variables to sex differences in humans is paramount, making it difficult if not impossible to parse out those contributions that are truly biological. The study of animals provides us the opportunity to understand the magnitude and scope of biologically based sex differences in the brain, and understanding the cellular mechanisms provides us insight into novel sources of brain plasticity. Many sex differences are established during a developmental sensitive window by differences in the hormonal milieu of males versus females. The neonatal testis produces large amounts of testosterone which gains access to the brain and is further metabolized into active androgens and estrogens which modify brain development. Major parameters that are influenced by hormones include neurogenesis, cell death, neurochemical phenotype, axonal and dendritic growth, and synaptogenesis. Variance in these parameters results in sex differences in the size of particular brain regions, the projections between brain regions, and the number and type of synapses within particular brain regions. The cellular mechanisms are both region and endpoint specific and invoke many surprising systems such as prostaglandins, endocannabinoids, and cell death proteins. Epigenetic modifications to the genome both establish and maintain sex differences in the brain and behavior. By understanding when, why, and how sex differences in the brain are established, we may also learn the source of strong gender biases in the relative risk and severity of numerous neurological diseases and disorders of mental health. Boys are much more likely to be diagnosed with autism spectrum or attention and hyperactivity disorders, as well as speech and language deficits, compared to girls. By contrast, women are more likely to suffer from affective disorders, such as depression, anxiety, compulsion, and eating disorders and more likely to experience autoimmune and neurodegenerative disorders. Schizophrenia with an early onset is more common in males but a late-onset version is markedly more frequent in females. Male biased disorders have origins in development while female biased disorders are almost exclusively post-puberty. This remarkable shift in disease risk demands our attention. Novel insights into the biological origins of disease are also gained by comparing and contrasting the same processes in different sexes.

Book Description
A collection of foundational texts on the nature and behavioral consequences of sex differences in the brain, allowing readers to follow the development of a rapidly growing but contentious field and giving them the tools to analyze emerging scientific findings from many perspectives. 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.

Book Description
Female and male brains are different, thanks to hormones coursing through the brain before birth. That’s taught as fact in psychology textbooks, academic journals, and bestselling books. And these hardwired differences explain everything from sexual orientation to gender identity, to why there aren’t more women physicists or more stay-at-home dads. In this compelling book, Rebecca Jordan-Young takes on the evidence that sex differences are hardwired into the brain. Analyzing virtually all published research that supports the claims of “human brain organization theory,” Jordan-Young reveals how often these studies fail the standards of science. Even if careful researchers point out the limits of their own studies, other researchers and journalists can easily ignore them because brain organization theory just sounds so right. But if a series of methodological weaknesses, questionable assumptions, inconsistent definitions, and enormous gaps between ambiguous findings and grand conclusions have accumulated through the years, then science isn’t scientific at all. Elegantly written, this book argues passionately that the analysis of gender differences deserves far more rigorous, biologically sophisticated science. “The evidence for hormonal sex differentiation of the human brain better resembles a hodge-podge pile than a solid structure...Once we have cleared the rubble, we can begin to build newer, more scientific stories about human development.”

Book Description
What controls our sex lives? Our brains. Yet there is surprisingly little research into how our brains influence one of the most fundamental of all human behaviors. And there is even less understanding of what can happen to the sexuality of a person who suffers a brain injury or illness such as a stroke, Parkinson’s disease, or dementia. In Sex in the Brain, clinical neuropsychologist Amee Baird explores fascinating case studies of dramatic changes in sexual behavior and explains what these exceptional stories have to say about human sexuality. She illuminates the extraordinary insights into how the brain works that injury or disease can divulge. Each chapter includes striking personal accounts, many from individuals Baird has met in her clinical practice, of unexpected shifts in sexuality. Until now these fascinating, frightening, and funny stories have been hidden in medical journals or untold outside of the clinical setting. This revealing and sometimes heartbreaking book unfolds a better understanding of the links between brain function and our sexual selves.

Book Description
Go beyond the headlines and the hype to get the newest findings in the burgeoning field of gender studies. Drawing on disciplines that include evolutionary science, anthropology, animal behavior, neuroscience, psychology, and endocrinology, Deborah Blum explores matters ranging from the link between immunology and sex to male/female gossip styles. The results are intriguing, startling, and often very amusing. For instance, did you know that. . . • Male testosterone levels drop in happy marriages; scientists speculate that women may use monogamy to control male behavior • Young female children who are in day-care are apt to be more secure than those kept at home; young male children less so • Anthropologists classify Western societies as "mildly polygamous" The Los Angeles Times has called Sex on the Brain "superbly crafted science writing, graced by unusual compassion, wit, and intelligence, that forms an important addition to the literature of gender studies."

Book Description
Since Dr. Brizendine wrote The Female Brain ten years ago, the response has been overwhelming. This New York Times bestseller has been translated into more than thirty languages, has sold nearly a million copies between editions, and has most recently inspired a romantic comedy starring Whitney Cummings and Sofia Vergara. And its profound scientific understanding of the nature and experience of the female brain continues to guide women as they pass through life stages, to help men better understand the girls and women in their lives, and to illuminate the delicate emotional machinery of a love relationship. Why are women more verbal than men? Why do women remember details of fights that men can’t remember at all? Why do women tend to form deeper bonds with their female friends than men do with their male counterparts? These and other questions have stumped both sexes throughout the ages. Now, pioneering neuropsychiatrist Louann Brizendine, M.D., brings together the latest findings to show how the unique structure of the female brain determines how women think, what they value, how they communicate, and who they love. While doing research as a medical student at Yale and then as a resident and faculty member at Harvard, Louann Brizendine discovered that almost all of the clinical data in existence on neurology, psychology, and neurobiology focused exclusively on males. In response to the overwhelming need for information on the female mind, Brizendine established the first clinic in the country to study and treat women’s brain function. In The Female Brain, Dr. Brizendine distills all her findings and the latest information from the scientific community in a highly accessible book that educates women about their unique brain/body/behavior. The result: women will come away from this book knowing that they have a lean, mean, communicating machine. Men will develop a serious case of brain envy.

Book Description
How much of sexual diversity is the result of nature versus nurture? Prevailing theories today lean heavily toward nature. Now a leading researcher in neuroscience and animal behavior shows how, in recent history, scientific claims about sex and gender differences have reflected the culture of the time. Although the conviction that genetics can explain everything is now widespread, the author demonstrates the interaction of culture and environment in the formation of behavioral traits and so provides an important corrective to popular notions of reductionism. Starting with a summary of sex and gender studies, Rogers explains the error of sex biasing, especially the once-assumed inferiority of women. She then addresses several modern studies and investigations, some of which assert that sex and gender differences are the product of genetic inheritance and hormones. Rogers uses laboratory evidence from studies of animals that help illustrate the biologically fluid properties of sex and gender. Sexing the Brain addresses a variety of topical questions: Are there sex differences in how we think and feel? Is language processed in different parts of the brain in men and women? Do social influences have a stronger influence on sexual behavior than sex hormone levels? Rogers concludes that "our biology does not bind us to remain the same.... We have the ability to change, and the future of sex differences belongs to us."

Book Description
There is a growing knowledge base in understanding the differences and similarities between women and men, as well as the diversities among women and sexualities. Although genetic and biological characteristics define human beings conventionally as women and men, their experiences are contextualized in multiple dimensions in terms of gender, sexuality, class, age, ethnicity, and other social dimensions. Beyond the biological and genetic basis of gender differences, gender intersects with culture and other social locations which affect the socialization and development of women across their life span. This handbook provides a comprehensive and up-to-date resource to understand the intersectionality of gender differences, to dispel myths, and to examine gender-relevant as well as culturally relevant implications and appropriate interventions. Featuring a truly international mix of contributors, and incorporating cross-cultural research and comparative perspectives, this handbook will inform mainstream psychology of the international literature on the psychology of women and gender.
