Sensory Systems of Primates


Book Description

Primates are avid explorers that utilize a variety of sensory clues from the environment. The special senses of olfaction, audition, and particu larly vision are thus of paramount significance in the evolution and adaptive radiation of the primates. It was with this in mind that this volume was planned to present some recent research advances. The chapter on olfactory communication among primates affords new insights concerning a sense which, though primatologists have generally relegated it to a minor role, is of considerable significance in the primates. The chapters on the auditory system are organized to stress three aspects: the receptive organ, the neural pathways, and the role of audition in primate communication. The visual system, the dominant special sense of primates, is analyzed with respect to two regions of the brain, namely, the organization of the superior colliculus and the visual cortex. Finally, the chapter on endocasts in the study of primate brain evolution will alert neurobiologists to the relevant information that can be unearthed from fossils embedded in the terrane. I wish to thank the publishers, and especially Miss Phyllis Straw and Mr. Seymour Weingarten, for their support, patience, guidance, and professional assistance.




Multisensory Object Perception in the Primate Brain


Book Description

It should come as no surprise to those interested in sensory processes that its research history is among the longest and richest of the many systematic efforts to understand how our bodies function. The continuing obsession with sensory systems is as much a re?ection of the fundamental need to understand how we experience the physical world as it is to understand how we become who we are based on those very experiences. The senses function as both portal and teacher, and their individual and collective properties have fascinated scientists and philosophers for millennia. In this context, the attention directed toward specifying their properties on a sense-by-sense basis that dominated sensory research in the 20th century seems a prelude to our current preoccupation with how they function in concert. Nevertheless, it was the concentrated effort on the operational principles of in- vidual senses that provided the depth of understanding necessary to inform current efforts to reveal how they act cooperatively. We know that the information provided by any individual sensory modality is not always veridical, but is subject to a myriad of modality-speci?c distortions. Thus, the brain’s ability to compare across the senses and to integrate the information they provide is not only a way to examine the accuracy of any individual sensory channel but also a way to enhance the collective information they make available to the brain.







Sensory Functions of the Skin in Primates


Book Description

Sensory Functions of the Skin in Primates: With Special Reference to Man deals with sensory functions of the skin in primates, particularly humans. The discussions are organized around three themes: mechanoreception, thermoception, and nociception. Comprised of 43 chapters, this volume begins with a detailed treatment of the natural and paranatural stimulation of sensory receptors, followed by an analysis of a theory of sympathetic-sensory coupling. The reader is then introduced to the "receptripse", the desmosome-like lamellar-axonal junction subserving mechano-electric transduction and inducing the sympathetic actions on the pacinian sensor. Subsequent chapters focus on differences in timing of corticocuneate and corticogracile actions; organization and neuronal morphology of the spinocervical tract; skin mechanoreceptors in the human hand; and cellular mechanisms in the parietal cortex in alert monkeys. The book also examines the response of central trigeminal neurons to cutaneous thermal stimulation and the role of thermoreceptors in thermoregulation. This monograph will be of interest to specialists in fields ranging from anatomy and biology to physiology and neurophysiology.




The Squirrel Monkey


Book Description

The Squirrel Monkey is devoted to the common South American squirrel monkey, Saimiri sciureus. In light of the growing number of squirrel monkeys being established each year in many laboratories, there appeared the need to pool existing knowledge in concise form. The present volume, the first of its kind on any single primate, attempts to meet this need. The topics that have been selected cover thoroughly areas of research in which Saimiri has been utilized. This material ranges widely from taxonomy and behavioral studies through husbandry and clinical management of the species, to investigations in aerospace medicine and in a number of basic biological sciences. Since the problems encountered in the squirrel monkey, though sometimes taking a particular form, are not unique in principle, the authors have attempted to provide an appropriate phylogenetic context for their material. It is hoped as a result that this compendium may serve as a valuable source of information during various phases of work on other subjects of primatological and comparative biological investigation as well.




Primate Models of Children's Health and Developmental Disabilities


Book Description

The rate of neurodevelopmental disabilities, including autism, mental retardation, hearing loss and attention deficit hyperactivity disorder is rising in the United States. Although estimates of the prevalence of these disorders vary, figures from the CDC indicate that 4% of all school age children are developmentally disabled. During infancy, many important milestones in behavioral development are shared between human and nonhuman primates. Learning more about the causes of abnormal development in monkeys has provided important insights into the mechanisms underlying neurodevelopmental disabilities in human infants. This book documents the latest research not commonly found in other references, and provides a comprehensive look at the results from decades of work with nonhuman primates as it relates to child development and disability. Includes hot topics such as early chemical exposures, immunological influences on development, low birth weight, endocrine disrupters, pediatric AIDS, origin of childhood psychopathologies and assisted reproductive technology Represents the significant body of work accumulated since funding for research on developmental disabilities has increased substantially in recent years

The Primate Visual System


Book Description

Many recent developments in the field in recording, staining, genetic and stimulation techniques, in vivo, and in vitro have significantly increased the amount of available data on the primate visual system. Written with contributions from key neurobiologists in the field, The Primate Visual System will provide the reader with the latest developments, examining the structure, function and evolution of the primate visual system. The book takes a comparative approach as a basis for studying the physiological properties of primate vision and examines the phylogenetic relationship between the visual systems of different primate species. Taken from a neurobiologist’s perspective this book provides a unique approach to the study of primate vision as a basis for further study into the human visual system. Altogether an important overview of the structure, function and evolution of the primate visual system from a neurobiologist’s perspective, written specifically for higher level undergraduate and graduate students taking courses in neuroscience, physiology, optics/ visual science, as well as a valuable read to researchers new to the field.




Post-Genome Biology of Primates


Book Description

In 2001, first reports of the human draft genome were published. Since then, genomes of many other organisms have been sequenced, including several primate species: the chimpanzee, rhesus macaque, gorilla, orangutan, gibbon, baboon, marmoset, tarsier, galago, lemur, and more recently Neanderthals. In a new era of "post-genome biology", scientists now have the vast amount of information revealed by genome research to confront one of the most challenging, fundamental questions in primatology and anthropology: What makes us human? This volume comprises a collection of articles on a variety of topics relevant to primate genomes, including evolution, human origins, genome structure, chromosome genomics, and bioinformatics. The book covers the cutting-edge research in molecular primatology and provides great insights into the functional diversity of primates. This valuable collection will benefit researchers and students, including primatologists, anthropologists, molecular biologists, evolutionary biologists, and animal behaviorists.
