Excerpt from Anatomical and Physiological Studies on the Growth of the Inner Ear of the Albino Rat Thus determinations have been made on the diameters of the cells of the ganglion spirale and of their nuclei at different ages; of the nucleus-plasma ratios and of their growth in relation to those of other portions of the membranous cochlea. For the cells of the vestibular ganglion similar determinations were also made. Finally, these results have been compared with those Obtained from the study of other craniospinal ganglia in the albino rat. In presenting my results I shall begin with a description of the changes in the larger portions of the membranous cochlea and pass from these to the cell elements themselves, and then to the observations on the ganglion cells and to the correlation between hearing and the growth of the cochlea.

This preface is addressed to the reader who wishes to inquire into the prevailing concepts, hypotheses and theories about development of sensory systems and wants to know how they are exemplified in the following chapters. I believe that science is hypothesis and theory and that the growth and evolution of any branch of science can be measured by the degree to which its theories have been reified. By that standard, one must conc1ude that developmental neuro biologie is in its infancy. The rapid accumulation of observations which has occurred in this branch of science in the past century leads to progress only to the extent that the facts validate or falsify hypotheses. The following chapters show that we have a plethora of facts but a dearth of hypotheses. Another index of the maturity of any branch of science is its level of historical self-awareness. Because the history of any branch of science is essentially the history of ideas and of the rise and fall of theories, the level of historical awareness is related to the extent to which reification of its hypothetical constructs has advanced. It is largely because few theories of development of sensory systems, or indeed, of developmental neurobiology, have progressed far in the process of reification that the his tory of developmental neurobiology remains unwritten. The subject of this volume is hardly mentioned in the many books devoted to the history of related disciplines.

In September 1985, NATO sponsored an Advanced Study WOl'kshop entitled, "Noise-Induced Hearing Loss: Basic and Applied Aspects." Tne meeting was held in a mountain retreat near Lucca, Italy and was attended by scientists, clinicians, and public officials from 12 countries. This was the third in a series of such conferences organized by the authors. The first two were supported by the United States National Institute of Occupational Safety and Health; their proceedings were published as "The Effects of Noise on Hearing" in 1976 and "New Perspectives on Noise-Induced Hearing Loss" in 1982. The Organizing Committee approached NATO because it was felt that the problem of noise was common to all industrialized countries and was an especially serious problem for the military. Thus, the NATO sponsorship and the Italian site of the meeting were part of the Organizing Committee's plan to obtain an international and thorough repr'esentation on the problem of noise-induced hearing loss. The NATO meeting and proceedings followed the format of the previous two symposia with an initial focus on the anatomical and physiological disturbances resulting from noise-induced hearing loss. This was followed by sections devoted to studies of a more applied nature involving general auditory performance in noise, issues associated with the establishment of noise-exposure criteria, nonauditory effects of noise, and the interaction of noise with other agents.

The small but growing body of information about auditory processes in infancy is a tribute to the ingenuity and persistence of investigators in this realm. Undeter red by the frequent expressions of boredom, rage, and indifference in their subjects, these investigators nevertheless continue to seek answers to the intrigu ing but difficult questions about the course of auditory development. In the spring of 1981, a group of leading scholars and researchers in audi tion gathered to discuss the topic, Auditory Development in Infancy, at the 11th annual psychology symposium at Erindale College, University of Toronto. They came from both sides of the Atlantic and from various disciplines, including audiology, neurology, physics, and psychology. They shared their views on theory and data, as well as their perspectives from the laboratory and clinic. One unexpected bonus was an unusually distinguished audience of researchers and clinicians who contributed to lively discussion within and beyond the formal sessions.

Development of Perception: Psychobiological Perspectives, Volume 1, Audition, Somatic Perception, and the Chemical Senses, is the first of a two-part series covering vision, audition, olfaction, taste, tactile sensitivity, and sensory-motor activity during ontogenesis. The focus is on approaches to perceptual development that incorporate a psychobiological perspective. The present volume contains both overviews and specific discussions of audition, somatic perception, and the chemical senses aimed at the anatomical, neurophysiological, and behavioral levels. The book is organized into four parts. Parts A and B are devoted to aspects of auditory perceptual development in animals and humans, respectively. These include studies on the development of species-specificity in duckling auditory perception; the functional role of auditory perception in parent-offspring recognition in birds; the development of auditory localization in human infants; and experiential components in the development of speech perception. Part C covers issues of somatosensory and sensorimotor development, including pioneering studies of development and plasticity in the neural structures of specialized somatosensory areas. Part D contains chapters on the development of olfaction and taste.

Studies on the Development of Behavior and the Nervous Systems, Volume 4: Early Influences discusses the effect of various exogenous factors on the early development of behavior and the nervous system. This volume is divided into three sections encompassing nine chapters that specifically consider the prenatal and postnatal effects of drugs, radiation, hormones, nutrition, sensory experience, trauma, and environmental enrichment. Section 1 initially describes the principles of teratology as they apply to functional or behavioral manifestations of prenatally administered drugs. This topic is followed by discussions on the radiation effects on developing mammals; the mechanisms of malformation involved; the use of malformed animals to find correlations between developing brain and behavior; and radiation hazard prevention in humans. This section also deals with the influence of hormones early in life upon sex differences in the behavior of adults and the effects of prenatal stress on offspring behavior. Section 2 examines the significance of proper maternal nutrition in early brain development and the evidence for long-term effects of undernutrition during the brain growth spurt. This section also looks into the behavioral implications of the various methods for producing early undernutrition in experimental animals and their possible relevance to the human condition. Section 3 describes the manipulation of early sensory experience, from total removal of sensory input to modification of stimulus quality, and the effects of such manipulations on the auditory, gustatory, olfactory, tactile, and visual systems. This section also provides an overview of auditory maturation and the consequences of acoustic trauma in the adult. This book is of great value to neurodevelopmental biologists and researchers.

In contrast to the level of interest which is paid to the orga nization of meetings about the structure and function of the audi tory periphery, the central auditory system has received little attention in the last several years. However, much recent data accu mulated during this period has provided auditory physiologists with new ideas about the function of the central auditory system. The successful exploration of new anatomical tracing techniques (triti ated aminoacids, horseradish peroxidase, 2-deoxyglucose) together with the collection of electrophysiological data obtained with intra cellular and extracellular recordings from the receptors and neurones in the auditory pathway have considerably deepened our understanding of central auditory function. Particular interest was concentrated upon the development of the auditory system under normal conditions and in conditions ofaudi tory deprivation. Although, from the methodological point of view, the conditions of reversible auditory deprivation are complicated, promising new data appeared in this field. Similarly the specific ability of the auditory system to encode communication signals and speech sounds has been examined in many laboratories allover the world. A very fruitful method. based upon the results of electrical stimulation of cochlear nerve fibres in experimental animals, is the application of neuroprostheses in deaf patients. At the present time, the method still does not meet all requirements and many improvements will be necessary. Undoubtedly the exploration of the results of recent physiological experiments may help in the further improvement of neuroprostheses.

Development of Auditory and Vestibular Systems is a collection of papers from noted scientists from different disciplines that discuss the state of advancement and perspectives on the development of auditory and vestibular function. The book is divided into three parts. Part I deals with the maturation and development of the different parts of the ear; the development of hearing; and the effects of harmful factors to its development. Part II talks about the development of the vestibular system, its embryogenesis and innervation, and its pathological maturation. The text is recommended for doctors, especially those who specialize in otology and audiology and want to either be updated in the findings about the developments in the field, or conduct studies regarding the developments of these senses.
