Book Description :

The nervous system has a remarkable capacity for self-reorganization, and in this first systematic analysis of the interaction between hormones and brain plasticity, Luis Miguel Garcia-Segura proposes that hormones modulate metaplasticity in the brain. He covers a wide variety of hormones, brain regions, and neuroplastic events, and also provides a new theoretical background with which to interpret the interaction of hormones and brain remodeling throughout the entire life of the organism. Garcia-Segura argues that hormones are indispensable for adequately adapting the endogenous neuroplastic activity of the brain to the incessant modifications in external and internal environments. Their regulation of neuroplastic events in a given moment predetermines new neuroplastic responses that will occur in the future, adapting brain reorganization to changing physiological and behavioral demands throughout the life of the organism. The cross-regulation of brain plasticity and hormones integrates information originated in multiple endocrine glands and body organs with information coming from the external world in conjunction with the previous history of the organism. Multiple hormonal signals act in concert to regulate the generation of morphological and functional changes in neural cells, as well as the replacement of neurons, glial, and endothelial cells in neural networks. Brain remodeling, in turn, is involved in controlling the activity of the endocrine glands and regulating hormonal secretions. This bidirectional adjustment of brain plasticity in response to hormonal inputs, and adjustment of hormonal concentrations in response to neuroplastic events are crucial for maintaining the stability of the inner milieu and for the generation of adequate behavioral responses in anticipation of--and in adaptation to--new social and environmental circumstances and life events, including pathological conditions.

Book Description :

When there is uncertainty about the gender identity or social gender role of an individual, determining exactly who the opposite sex is can be a complicated question for both the transgender person and for those who seek to relate to her. Written in both an enlightened and a reader friendly style interspersed with vignettes, When the Opposite Sex Isn’t offers a combination of insights and common sense understanding of the diversity of the human condition together with concepts of gender and sexuality that expand the horizons of any mental health professional, regardless of the clinical focus of his or her work. Samons challenges concepts once taken for granted, thus providing stimulus for creative thinking which many lay readers will also find interesting and entertaining, whether or not they are (thus far) acquainted with a transgender person.

GET BOOK

Book Description :

Technologies of Sexuality, Identity and Sexual Health highlights the complex ways in which sexuality is expressed and enacted through local ideologies, global identities and material cultures, and their influence on people's sexual health and wellbeing. Its impetus is the renewed interest in technology and the 'social life of things, ' including pharmaceuticals, expanded sexual and related surgery, the growing exploitation of markets for sexual and contraceptive products, and the impact of these on sexual and health practices and outcomes. The book is organised into three parts. The first section on cultural practices consists of four chapters exploring the durability of various traditional practices, products and beliefs about bodies, illustrating how these technologies enable the exercise of power and draw attention to the complex tasks for individuals who may resist, challenge or avoid their imposition.The second part looks at commonalities across cultural borders and gendered identities -- how products and procedures travel, not only in formal economies and through the vectors of globalisation, but also informally, carried by individuals across cultural and social boundaries though sexual, social and commercial interactions. The final part discusses power and cultural norms in relation to contemporary technologies and to modern rights, places and spaces -- with violence highlighted as a technology of control. The volume brings together anthropologists, sociologists and cultural studies scholars, both senior and emerging scholars from around the globe -- and contains ethnographic data from Australia (indigenous and Anglo), Bangladesh, Brazil, France, India, Indonesia, Mozambique and Zambia, Papua New Guinea, Turkey, the United States, and the cyberworld. Offering an important and topical contribution to the developing global literature on sexuality, sexual identity, culture and health, it is of interest to researchers and advanced students in these areas

Book Description :

The past decade has witnessed a resurgence of interest in Marxism both within and without the academy. Marxian frameworks, concepts and categories continue to be narratively relevant to the features and events of contemporary capitalism. Most crucially, an attention to shifting cultural conditions has lead contemporary researchers to re-confront some classical and essential Marxist concepts, as well as elaborating new critical frameworks for the analysis of capitalism today. The SAGE Handbook of Marxism showcases this cutting-edge of today’s Marxism. It advances the debate with essays that rigorously map and renew the concepts that have provided the groundwork and main currents for Marxist theory, and showcases interventions that set the agenda for Marxist research in the 21st century. A rigorous and challenging collection of scholarship, this book contains a stunning range of contributions from contemporary academics, writers and theorists from around the world and across disciplines, invaluable to scholars and graduate students alike. Part 1: Reworking the critique of political economy Part 2: Forms of domination, subjects of struggle Part 3: Political perspectives Part 4: Philosophical dimensions Part 5: Land and existence Part 6: Domains Part 7: Inquiries and debates

Book Description :

Developmental Neuropsychobiology is a compendium of papers that deals with developmental neuroscience and developmental psychology, as well as the broad range of approaches toward brain-behavior development. One paper reviews the embryonic mechanisms including the pattern formation that develops in a single fertilized egg, particularly focusing on limb innervation as a special case of pattern formation. Another paper discusses the regulation of nerve fiber elongation during embryogenesis. One author analyzes the pathways and changing connections in the nervous system of the insect: he shows that manipulating neural organization by grafting results in the ability of the transplanted sensory cells to find the proper central connections. Another paper reviews the sex differences in developmental plasticity of behavior and the brain. These differences point to the vulnerability of males during development to incidences of autism, dyslexia, or cerebral palsy compared to females. One paper also examines alternative perceptions of parent- offspring relationships. This collection can prove helpful for researchers, students, and academicians involved in the disciplines of biological or psychological sciences.

Book Description :

The first comprehensive synthesis on development and evolution: it applies to all aspects of development, at all levels of organization and in all organisms, taking advantage of modern findings on behavior, genetics, endocrinology, molecular biology, evolutionary theory and phylogenetics to show the connections between developmental mechanisms and evolutionary change. This book solves key problems that have impeded a definitive synthesis in the past. It uses new concepts and specific examples to show how to relate environmentally sensitive development to the genetic theory of adaptive evolution and to explain major patterns of change. In this book development includes not only embryology and the ontogeny of morphology, sometimes portrayed inadequately as governed by "regulatory genes," but also behavioral development and physiological adaptation, where plasticity is mediated by genetically complex mechanisms like hormones and learning. The book shows how the universal qualities of phenotypes--modular organization and plasticity--facilitate both integration and change. Here you will learn why it is wrong to describe organisms as genetically programmed; why environmental induction is likely to be more important in evolution than random mutation; and why it is crucial to consider both selection and developmental mechanism in explanations of adaptive evolution. This book satisfies the need for a truly general book on development, plasticity and evolution that applies to living organisms in all of their life stages and environments. Using an immense compendium of examples on many kinds of organisms, from viruses and bacteria to higher plants and animals, it shows how the phenotype is reorganized during evolution to produce novelties, and how alternative phenotypes occupy a pivotal role as a phase of evolution that fosters diversification and speeds change. The arguments of this book call for a new view of the major themes of evolutionary biology, as shown in chapters on gradualism, homology, environmental induction, speciation, radiation, macroevolution, punctuation, and the maintenance of sex. No other treatment of development and evolution since Darwin's offers such a comprehensive and critical discussion of the relevant issues. Developmental Plasticity and Evolution is designed for biologists interested in the development and evolution of behavior, life-history patterns, ecology, physiology, morphology and speciation. It will also appeal to evolutionary paleontologists, anthropologists, psychologists, and teachers of general biology.

Book Description :

Sex determination, differentiation and gamete maturation are well organized molecular events in vertebrates. In vertebrates, sex determination and differentiation are two important events in the development of gonads (testis or ovary). Sex determination is the genetic (sex chromosomes) or environmental process by which the sex (male or female) of an individual is established. During embryonic development, primordial germ cells migrate from the site of origin to the gonadal primordia where they differentiate along with somatic cells and finally form the indifferent/bipotential gonads. Depending on the action of various factors the bipotential gonads give rise to either testis or ovaries. In most vertebrates, excluding fishes and some amphibians, the event of sex determination is controlled genetically and later the progression of gonadal development is controlled by hormones and other factors. Interestingly, these processes in fishes are controlled not only genetically but also through hormones or environmental factors. These characteristics make fish the champions of sex reversal and serve as excellent animal models to precisely understand sexual development. The next interesting aspect is meiotic maturation which is essentially mediated by gonadotropins and progesterone metabolites to trigger final gamete maturation in fishes which is different from mammals. The novel aspects pertaining to gamete maturation has been studied in great detail in fish which depicts precise regulatory events of gamete maturation.

Language : En, Es, Fr & De

GET BOOK

Book Description :

This book focuses on explaining the distribution of sexual systems (simultaneous hermaphroditism, sequential hermaphroditism, environmental sex determination,dioecy, androdioecy, etc.) among taxa, which remains a major challenge in evolutionary biology. Although significant advances have been made for angiosperms, there is not yet a theory that predicts the sexual system for the majority of animal taxa, and other taxa of plants also remain poorly understood. The problem, particularly for animals, is that sexual systems can be very conservative, with whole phyla and classes being characterized by a single sexual system; for example essentially the whole phylum Platyhelminthes is simultaneously hermaphroditic, whereas the Insecta (Hexapoda) and the Tetrapoda among the vertebrates, are exclusively dioecious. Sex allocation theory on the other hand, suggests that sexual systems should be highly responsive to evolution, changing with population density, life span, patterns of resource availability, etc. The book provides an overview of the topic and then presents a series of chapters, each dealing with a taxon with substantial lability in sexual system in order to identify the factors associated with changes in sexual system in each case. By doing so, the authors reveal factors that have not been considered in formal theory but seem to have a major impact on transitions between sexual systems. This book appeals to a wide readership in fields from zoology and evolutionary biology to botany.

Book Description :

Thomas McNamara, in Evolution, Culture, and Consciousness, presents the first comprehensive theory of human perception and consciousness based on the generally accepted principles of evolutionary psychology. This theory, building on the best evolutionary research, explains that just a few simple neurological changes in the primate brain account for human speech, self-consciousness and the creation of meaning out of experience. All primates can learn, but our species evolved a new instinct for learning, which makes childhood learning just as powerful as the other biological instincts found in all other primates. McNamara shows that children are genetically programmed to learn not just what to think, but how to think, shaping the preconscious process for creating meaning out of experience. However, because our environment has changed radically since our origin, this archaic form of consciousness has become a major block to human development and success. After explaining how we have all been programmed to preconsciously create meaning out of experience, McNamara shows how we can create a new and more successful way of thinking and feeling, resulting in a happier, more productive, stress free life.
