Female partner preferences

Thirty years ago, the group of Baulieu and colleagues discovered that certain steroid hormones were present in higher amounts in the brain than in the plasma, and also found that suppression of circulating steroids by adrenalectomy and castration did not affect the concentration of pregnenolone, dehydroepiandrosterone and their sulfate esters in the rat brain. These seminal observations led to the concept that the brain, in very much the same way as the adrenal cortex, testis, ovary and placenta, was capable of synthesizing steroids. These brain born steroids, called neurosteroids, have been found to exert a vast array of biological activities. A number of steroidogenic enzymes have now been identified in the central nervous system by immunohistochemistry and in situ hybridization, and the neuronal and hormonal mechanisms regulating the biosynthesis of neurosteroids have been partially elucidated. The aim of this Research Topic is to celebrate three decades of research on neurosteroids by gathering a bouquet of review papers and original articles from leading scientists in the flourishing field of neurosteroids.

Female partner preferences enhance offspring ability to survive an infection

Neurobiology of Mental Illness. Dennis S. Charney , Joseph D. Our understanding of the neurobiological basis of psychiatric disease has accelerated in the past five years. The fourth edition of Neurobiology of Mental Illness has been completely revamped given these advances and discoveries on the neurobiologic foundations of psychiatry. Like its predecessors the book begins with an overview of the basic science. The emerging technologies in Section 2 have been extensively redone to match the progress in the field including new chapters on the applications of stem cells, optogenetics, and image guided stimulation to our understanding and treatment of psychiatric disorders.

Sections' 3 through 8 pertain to the major psychiatric syndromes-the psychoses, mood disorders, anxiety disorders, substance use disorders, dementias, and disorders of childhood-onset. Each of these sections includes our knowledge of their etiology, pathophysiology, and treatment.

The final section discusses special topic areas including the neurobiology of sleep, resilience, social attachment, aggression, personality disorders and eating disorders. In all, there are 32 new chapters in this volume including unique insights on DSM-5, the Research Domain Criteria RDoC from NIMH, and a perspective on the continuing challenges of diagnosis given what we know of the brain and the mechanisms pertaining to mental illness.

This book provides information from numerous levels of analysis including molecular biology and genetics, cellular physiology, neuroanatomy, neuropharmacology, epidemiology, and behavior. In doing so it translates information from the basic laboratory to the clinical laboratory and finally to clinical treatment. No other book distills the basic science and underpinnings of mental disorders and explains the clinical significance to the scope and breadth of this classic text.

The result is an excellent and cutting-edge resource for psychiatric residents, psychiatric researchers and doctoral students in neurochemistry and the neurosciences. Buxbaum , Pamela Sklar , Eric J. Neurobiology of Mental Illness Dennis S.

He is a world expert in the neurobiology and treatment of mood and anxiety disorders. He has made fundamental contributions to the understanding of neural circuits and neurochemistry related to human anxiety, fear, mood and discovery of new treatment for mood and anxiety disorders. He later expanded this area into pioneering research related to the psychobiological mechanisms of human resilience to stress.

Joseph D. He is a world-renowned molecular geneticist and spearheads research into human psychiatric and neurological diseases. Buxbaum helps set the research direction for the Department, which is ranked among the top 20 psychiatry departments in the country in NIH funding. She is a neuroscientist, human geneticist and clinical psychiatrist investigating the genetic causes of psychiatric disorders, including schizophrenia and bipolar disorder.

A major focus of her prior work has been to identify susceptibility genes for psychiatric diseases by applying tools developed for understanding and characterizing human sequence variation. Eric J. In , Dr. Nestler has been a pioneer in the field of molecular psychiatry, whose research has helped us understand the molecular mechanisms of addiction and depression based on work in animal models.

Mating preferences

This popular behavioral endocrinology text provides detailed information on what hormones are, how they affect cells, and how such effects can alter the behavior of animals, including humans. Presenting a broad continuum of levels of analysis, from molecular to evolutionary, the book discusses how genes work, the structure of cells, the interactions of endocrine organs, the behavior of individuals, the structure of social hierarchies, and the evolution of mating systems. The second edition, while maintaining the strengths of the first edition, has been thoroughly revised to reflect recent developments in genetics and molecular biology and related social concerns. It contains four new chapters: on the use of molecular biology techniques in behavioral endocrinology, on psychoneuroimmunology, on hormonal influences on sensorimotor function, and on cognitive function in nonhuman animals.

Metrics details. It is often suggested that mate choice enhances offspring immune resistance to infectious diseases. To test this hypothesis, we conducted a study with wild-derived house mice Mus musculus musculus in which females were experimentally mated either with their preferred or non-preferred male, and their offspring were infected with a mouse pathogen, Salmonella enterica serovar Typhimurium. We found that offspring sired by preferred males were significantly more likely to survive the experimental infection compared to those sired by non-preferred males.

Female partner preferences enhance offspring ability to survive an infection.

In the decade since the publication of the last edition, the study of reproductive physiology has undergone monumental changes. Chief among these advances are in the areas of stem cell development, signaling pathways, the role of inflammation in the regulatory processes in the various tissues, and the integration of new animal models which have led to a greater understanding of human disease. The new edition synthesizes all of this new information at the molecular, cellular, and organismal levels of organization and present modern physiology a more understandable and comparative context. Tony M. Plant studied for his PhD with Dr. Richard P. Michael in London and completed his postdoctoral training with Dr. Ernst Knobil in Pittsburgh in

Mate preferences in humans refers to why one human chooses or chooses not to mate with another human and their reasoning why see: Evolutionary Psychology, mating. Men and women have been observed having different criteria as what makes a good or ideal mate gender differences. A potential mate's socioeconomic status has also been seen as having a noticeable effect, especially in developing areas where social status is more emphasized. In humans, when choosing a mate of the opposite sex, females place high preference for a mate that is physically attractive.
