Oral Physiology contains the proceedings of the Wenner-Gren Center International Symposium held in Stockholm, Sweden in August 1971. Contributors explore common problems and trends in oral physiology, from the regulation of salivary glands and the role of electrolytes in the formation of saliva to neural mechanisms underlying salivary excretion, the effect of citric acid on parotid flow, and secretion of salivary glycoproteins. Circulation of the tongue, monitoring of oral circulation, physiology of mastication, and development of fetal gustatory receptors are also covered. This volume consists of 27 chapters and begins with a discussion of mechanisms underlying control of different types of effector cells that comprise the salivary gland. The reader is methodically introduced to the nerves to the parotid gland, electrolyte and water transport in salivary glands, neural mechanisms controlling the excretion of saliva, and how the function of salivary fibers is affected by different conditions situated along the course of the seventh and ninth cranial nerves. The next chapters focus on the effect of citric acid on the variance of the parotid flow rate, ductal transport processes and glandular effects of neurotransmitters and pharmacological agents, and neuro-effector sites in salivary glands. The book concludes by presenting experimental evidence indicating that nerve impulses can be recorded from dentine. This book will be useful for researchers and teachers not only of oral physiology, but also of odontology and medicine in general.

Dynamics of Degeneration and Growth in Neurons is a collection of papers presented at the International Symposium on the Dynamics of Degeneration and Growth in Neurons, held in Stockholm, Sweden, on May 16-18, 1973. Contributors explore the dynamics of degeneration and growth of central and peripheral neurons, touching on a wide range of topics such as the neurotoxic action of 6-hydroxy-dopa on central catecholamine neurons; axonal transport of proteins in growing and regenerating neurons; and collateral reinnervation in the central nervous system. Comprised of 50 chapters, this volume begins with an overview of degeneration processes in central and peripheral neurons. Results of microfluorimetric and neurochemical studies on degenerating and regenerating adrenergic nerves are presented. The next section is devoted to axoplasmic transport as a mechanism for axonal support and growth and includes chapters dealing with the effects of degeneration and axoplasmic transport blockade on synaptic ultrastructure, function, and protein composition; the role of axoplasmic flow in trophism of skeletal muscle; and proximodistal transport of acetylcholine in peripheral cholinergic neurons. The remaining chapters discuss the nerve growth factor receptor and its specific binding in sympathetic ganglia; the noradrenergic innervation of cerebellar Purkinje cells; and the possible role of brain and peripheral monoamines in the ontogenesis of normal and drug-induced responses in the immature mammal. This book will be of interest to physiologists and neurologists.

Dyslexia: Neuronal, Cognitive & Linguistic Aspects focuses on the desire of scholars to identify the etiology of dyslexia and how it affects the ability of children to read and write. This book features the works of authors who have conducted extensive research on dyslexia. In the neuronal aspect of defining the origin of dyslexia, the selection commences by defining the neuroanatomical features of language and dyslexia. This discussion is followed by a tracking of the sections of the brain that are involved in this kind of deficiency. In the cognitive facet, the selection features discussion on how the right hemisphere functions relative to the ability to read. This topic is followed by several observations, which point out that the right hemisphere has no direct influence on a person''s ability to read; however, it is stressed that this part of the brain has visuo-spatial capabilities. The discussion is followed by a presentation of opthalmological findings among children with learning difficulties. The book then proceeds to the relationship of dyslexia with visual problems and linguistic awareness. In this regard, questions on the ability of children to be able to read prior and during their school years are raised. The selection ends with a discussion on how to treat dyslexia through the use of computers. This book is a great source of information for neurophysiologists, psychophysiologists, ophthalmologists, and teachers who are interested in helping children learn to read and write.
