We inherit mechanisms for survival from our primeval past; none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: it changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world. The ancient world shaped the human brain, but the modern world is shaped by that brain. How does this world, with all its cultural, political, and social variations, deal with and control the primeval role of testosterone, which continues to be essential for the survival of the species? Sex, aggression, winning, losing, gangs, war: the powerful effects of testosterone are entwined with them all. These are the ingredients of human history, so testosterone has played a central role in our story. In Testosterone, Joe Herbert explains the nature of this potent hormone, how it operates in mammals in general and in humans in particular, what we know about its role in influencing various aspects of behaviour in men, and what we are beginning to understand of its role in women. From rape to gang warfare among youths, understanding the workings of testosterone is critical to enable us to manage its continuing powerful effects in modern society.

How much control do we have over love? Much less than we like to think. All that mystery, all that poetry, all those complex behaviors sur­rounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brains. How does love begin? How can two strangers come to the conclusion that it would not only be pleasant to share their lives, but that they must share them? How can a man say he loves his wife, yet still cheat on her? Why do others stay in relationships even after the ro­mance fades? How is it possible to fall in love with the “wrong” person? How do people come to have a “type”? Physical attraction, jealousy, infidelity, mother-infant bonding—all the behaviors that so often leave us befuddled—are now being teased out of the fog of mystery thanks to today’s social neuroscience. Larry Young, one of the world’s leading experts in the field, and journalist Brian Alexander explain how those findings apply to you. Drawing on real human stories and research from labs around the world, The Chemistry Between Us is a bold attempt to create a “grand unified theory” of love. Some of the mind-blowing insights include: Love can get such a grip on us because it is, literally, an addiction. To a woman falling in love, a man is like her baby. Why it’s false to say society makes gender, and how it’s possible to have the body of one gender and the brain of another. Why some people are more likely to cheat than others. Why we sometimes truly can’t resist temptation. Young and Alexander place their revelations into historical, political, and social contexts. In the pro­cess, they touch on everything from gay marriage to why single-mother households might not be good for society. The Chemistry Between Us offers powerful in­sights into love, sex, gender, sexual orientation, and family life that will prove to be enlightening, contro­versial, and thought provoking.

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. Every brain begins as a female brain. It only becomes male eight weeks after conception, when excess testosterone shrinks the communications center, reduces the hearing cortex, and makes the part of the brain that processes sex twice as large. Louann Brizendine, M.D. is a pioneering neuropsychiatrist who 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 whom they’ll love. Brizendine reveals the neurological explanations behind why • A woman remembers fights that a man insists never happened • A teen girl is so obsessed with her looks and talking on the phone • Thoughts about sex enter a woman’s brain once every couple of days but enter a man’s brain about once every minute • A woman knows what people are feeling, while a man can’t spot an emotion unless somebody cries or threatens bodily harm • A woman over 50 is more likely to initiate divorce than a man 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.

WINNER OF THE 2017 ROYAL SOCIETY INSIGHT INVESTMENT SCIENCE BOOK PRIZE What the judges said: 'Every man and woman should read this book on gender bias ... an important, yet wickedly witty, book.' 'Fine's entertaining and thoughtful book is a valuable addition to the discussion about gender.' Ian Critchley, Sunday Times 'In addition to being hopeful, Fine is also angry. We should all be angry. Testosterone Rexis a debunking rumble that ought to inspire a roar.' Guardian 'A densely packed, spirited book, with an unusual combination of academic rigour and readability ... The expression "essential reading for everyone" is usually untrue as well as a clich�, but if there were a book deserving of that description this might just be it.' Antonia Macaro, Financial Times Testosterone Rex is the powerful myth that squashes hopes of sex equality by telling us that men and women have evolved different natures. Fixed in an ancestral past that rewarded competitive men and caring women, these differences are supposedly re-created in each generation by sex hormones and male and female brains. Testosterone, so we're told, is the very essence of masculinity, and biological sex is a fundamental force in our development. Not so, says psychologist Cordelia Fine, who shows, with wit and panache, that sex doesn't create male and female natures. Instead, sex, hormones, culture and evolution work together in ways that make past and present gender dynamics only a serving suggestion for the future - not a recipe. Testosterone Rexbrings together evolutionary science, psychology, neuroscience and social history to move beyond old 'nature versus nurture' debates, and to explain why it's time to unmake the tyrannical myth of Testosterone Rex. For fans of Fine - whose Delusions of Gender'could have far-reaching consequences as significant as The Female Eunuch' (Viv Groskop, Guardian) - and thousands of new readers, this is an upbeat, timely and important contribution to the debate about gender in society.

The recent explosion of neuroscience techniques has proved to be game changing in terms of understanding the healthy brain, and in the development of neuropsychiatric treatments. One of the key techniques available to us is functional magnetic resonance imaging (fMRI), which allows us to examine the human brain non-invasively, and observe brain activity in real time. Through fMRI, we are beginning to build a deeper understanding of our thoughts, motivations, and behaviours. Recent reports that some patients who have all indications of being in a persistent vegetative state show conscious awareness, and were able to communicate with researchers, demonstrate perhaps the most remarkable and dramatic use of fMRI. But this is just the most striking of a number of areas in which fMRI is being used to 'read minds', albeit in a very limited way. As neuroscientists unravel the regions of the brain involved in reward and motivation, and in romantic love, we are likely to develop the capacity to influence responses such as love using drugs. fMRI studies have also been used to indicate that many people who would not regard themselves as racist show a racial bias in their emotional responses to faces of another racial group. Meanwhile, the reliability of fMRI as a lie detector in murder cases is being debated - what if the individual simply believes, falsely, that he or she committed a murder? Sex, Lies, and fMRI takes readers beyond the media headlines. Barbara Sahakian and Julia Gottwald consider what the technique of fMRI entails, and what information it can give us, showing which applications are possible today, and which ones are science fiction. They also consider the important ethical questions these techniques raise. Should individuals applying for jobs as teachers or judges be screened for unconscious racial bias? What if the manipulation of love using 'love potions' was misused for economic or military ends? How far will we allow neuroscience to go? It is time to make up our minds.

Why do some people prefer heterosexual love while others fancy the same sex? Is sexual identity biologically determined or a product of convention? In this brilliant and provocative book, the acclaimed author of Myths of Gender argues that even the most fundamental knowledge about sex is shaped by the culture in which scientific knowledge is produced.Drawing on astonishing real-life cases and a probing analysis of centuries of scientific research, Fausto-Sterling demonstrates how scientists have historically politicized the body. In lively and impassioned prose, she breaks down three key dualisms - sex/gender, nature/nurture, and real/constructed - and asserts that individuals born as mixtures of male and female exist as one of five natural human variants and, as such, should not be forced to compromise their differences to fit a flawed societal definition of normality.
