Book Description
Parasites that manipulate the behaviour of their hosts represent striking examples of adaptation by natural selection. This field of study is now moving beyond its descriptive phase and into more exciting areas where the processes and patterns of such dramatic adaptations can be better understood. This innovative text provides an up-to-date, authoritative, and challenging review of host manipulation by parasites that assesses the current state of developments in the field and lays out a framework for future research. It also promotes a greater integration of behavioral ecology with studies of host manipulation (behavioral ecology has tended to concentrate mainly on behaviour expressed by free living organisms and is far less focused on the role of parasites in shaping behaviour). To help achieve this, the editors adopt a novel approach of having a prominent expert on behavioral ecology (but who does not work directly on parasites) to provide an afterword to each chapter.

Book Description
Enriched and Impoverished Environments: Effects on Brain and Behaviour is the most recent review of the active area of neuronal plasticity. The question of how experience is recorded is fundamental to psychology; speculations and investigations concerning the role of the brain in this process have entered a particularly exciting phase as of the late 1980's. Manipulations of environmental complexity is one of the earliest methods utilized in the study of neural plasticity. This monograph organizes the evidence to date concerning the responsiveness of neural and behavioural systems to external manipulation of the environment. Further consideration is given to the issues of causation of the general effects of environment on brain and behaviour.

Book Description
How we raise young children is one of today's most highly personalized and sharply politicized issues, in part because each of us can claim some level of "expertise." The debate has intensified as discoveries about our development-in the womb and in the first months and years-have reached the popular media. How can we use our burgeoning knowledge to assure the well-being of all young children, for their own sake as well as for the sake of our nation? Drawing from new findings, this book presents important conclusions about nature-versus-nurture, the impact of being born into a working family, the effect of politics on programs for children, the costs and benefits of intervention, and other issues. The committee issues a series of challenges to decision makers regarding the quality of child care, issues of racial and ethnic diversity, the integration of children's cognitive and emotional development, and more. Authoritative yet accessible, From Neurons to Neighborhoods presents the evidence about "brain wiring" and how kids learn to speak, think, and regulate their behavior. It examines the effect of the climate-family, child care, community-within which the child grows.

Book Description
When a chimpanzee stockpiles rocks as weapons or when a frog sends out mating calls, we might easily assume these animals know their own motivations--that they use the same psychological mechanisms that we do. But as Beyond the Brain indicates, this is a dangerous assumption because animals have different evolutionary trajectories, ecological niches, and physical attributes. How do these differences influence animal thinking and behavior? Removing our human-centered spectacles, Louise Barrett investigates the mind and brain and offers an alternative approach for understanding animal and human cognition. Drawing on examples from animal behavior, comparative psychology, robotics, artificial life, developmental psychology, and cognitive science, Barrett provides remarkable new insights into how animals and humans depend on their bodies and environment--not just their brains--to behave intelligently. Barrett begins with an overview of human cognitive adaptations and how these color our views of other species, brains, and minds. Considering when it is worth having a big brain--or indeed having a brain at all--she investigates exactly what brains are good at. Showing that the brain's evolutionary function guides action in the world, she looks at how physical structure contributes to cognitive processes, and she demonstrates how these processes employ materials and resources in specific environments. Arguing that thinking and behavior constitute a property of the whole organism, not just the brain, Beyond the Brain illustrates how the body, brain, and cognition are tied to the wider world.

Book Description
This volume brings together authors working on a wide range of topics to provide an up to date account of the underlying mechanisms and functions of neurogenesis and synaptogenesis in the adult brain. With an increasing understanding of the role of neurogenesis and synaptogenesis it is possible to envisage improvements or novel treatments for a number of diseases and the possibility of harnessing these phenomena to reduce the impact of ageing and to provide mechanisms to repair the brain.

Book Description
Development and Evolution of Brain Size: Behavioral Implications contains the proceedings of a symposium entitled ""Development and Evolution of Brain Size: Behavioral Implications,"" held at William Paterson College in Wayne, New Jersey, in April 1978. The papers explore the relationship between evolution and development and its implications for brain size and behavior. This book is comprised of 18 chapters and begins with an overview of the brain-behavior relationship, with emphasis on the importance of brain size for behavior; the effects of genetic selection for brain size on brain substructures and behavior; and whether genetic and environmental manipulations of brain size have similar consequences. The next two chapters explain evolutionary theory and the evolution of the human brain as well as diversity in brain size. A general model for brain evolution that offers some synthetic possibilities for approaching the questions of brain evolution, size, allometry, and reorganization is then described. The correlation between cerebral indices and behavioral differences is also discussed, along with biochemical correlates of selective breeding for brain size. The results of an experiment that assessed the effects of early undernutrition on brain and behavior of developing mice are presented. This monograph should be of interest to students and practitioners in a wide range of disciplines, including evolutionary biology and clinical psychology.

Book Description
The skin, the body’s largest organ, is strategically located at the interface with the external environment where it detects, integrates and responds to a diverse range of stressors, including solar radiation. It has already been established that the skin is an important peripheral neuroendocrine-immune organ that is closely networked with central regulatory systems. These capabilities contribute to the maintenance of peripheral homeostasis. Specifically, epidermal and dermal cells produce and respond to classical stress neurotransmitters, neuropeptides and hormones, production which is stimulated by ultraviolet radiation (UVR), biological factors (infectious and non-infectious) and other physical and chemical agents. Examples of local biologically active products are cytokines, biogenic amines (catecholamines, histamine, serotonin and N-acetyl-serotonin), melatonin, acetylocholine, neuropeptides including pituitary (proopiomelanocortin-derived ACTH, b-endorphin or MSH peptides, thyroid stimulating hormone) and hypothalamic (corticotropin-releasing factor and related urocortins, thyroid-releasing hormone) hormones, as well as enkephalins and dynorphins, thyroid hormones, steroids (glucocorticoids, mineralocorticoids, sex hormones, 7-δ steroids), secosteroids, opioids and endocannabinoids. The production of these molecules is hierarchical, organized along the algorithms of classical neuroendocrine axes such as the hypothalamic pituitary adrenal axis (HPA), hypothalamic-thyroid axis (HPT), serotoninergic, melatoninergic, catecholaminergic, cholinergic, steroid/secosteroidogenic, opioid and endocannabinoid systems. Disruptions of these axes or of communication between them may lead to skin and/or systemic diseases. These local neuroendocrine networks also serve to limit the effect of noxious environmental agents to preserve local and consequently global homeostasis. Moreover, the skin-derived factors/systems can also activate cutaneous nerve endings to alert the brain to changes in the epidermal or dermal environments, or alternatively to activate other coordinating centers by direct (spinal cord) neurotransmission without brain involvement. Furthermore, rapid and reciprocal communications between epidermal and dermal and adnexal compartments are also mediated by neurotransmission including antidromic modes of conduction. Lastly, skin cells and the skin as an organ coordinate and/or regulate not only peripheral but also global homeostasis.

Book Description
The Ontogeny of Vertebrate Behavior is a collection of articles focused on the comparative psychology researches. The text is devoted to the development of vertebrate behavior, emphasizes the ontogenetic determinants, and answers questions related to the differentiation of selected response systems. The book is organized into 10 chapters that feature the concepts of vertebrate behavior and its ontogeny. It presents the study of behavioral development, as well as the visual perceptual systems and its evolution. It explains the perceptual abilities of the human infant and the early experience and problem-solving behavior. Cerebral effects of environmental manipulation and the behavioral phenomena are explained. The book also talks about the ontogeny of emotional, play, and exploratory behaviors; of sexuality and maternal behavior; and of mother-infant relations. It also discusses the principle and procedure of imprinting. Finally, it explains the vocal learning of avian species and the ontogeny of language, as well as the vocal abnormalities. This text will be invaluable to the students, novices, and professionals in psychology, ethology, endocrinology, and behavioral and developmental biology.
