As a source of information on neuroanatomical research methods this Volume is not without precedent. In 1957, at the initiative of Dr. W. F. Windle, a conference was held at the National Institutes of Health, the proceedings of which, edited by Dr. Windle and published by C. C. Thomas under the title "New Research Tech niques of Neuroanatomy", rapidly became something like a standard reference in the field of Neuromorphology. The present editors were emboldened to seek support for a second expose of contemporary research methods in Neuroanatomy by the success of this earlier publication, as well as by the consideration that the years elapsed since its appearance have been, perhaps, more productive of new research methods and strategies in Neuroanatomy than were any dozen consecutive years since the golden decades of the 1870's and 1880's. The decision, which methods to include in this conference, has been a difficult one. For reasons of space alone it would have been impossible to do equal justice to techniques approaching the brain as a neuronal system, the brain as a tissue, or the neuron as a cell. As a brief inspection of the contents of this volume will show, the weight of choice fell upon the first of these alternatives. The reader will find, further more, that not all of the book is devoted to new methods in the strict sense.

Neuroanatomical Research Techniques discusses developments in major neuroanatomical research techniques. The book is organized into four parts. Part I deals generally with the preparation and study of brain tissue. It includes a chapter on the microscope, discussing optical magnification, limitations of microscopy, and optical contrasting methods. Other chapters summarize basic techniques for tissue preparation and sectioning; present guidelines for a number of standard, but essential, staining procedures; and present sophisticated and contemporary computer techniques that are proving to be invaluable as neuroanatomy evolves from a qualitative to a quantitative discipline. Part II deals with techniques often used for the study of normal tissue. These include the Golgi method, fluorescence histochemistry, techniques for staining single neurons, and the use of the electron microscope. Part III presents techniques for studying intrinsic connections of the nervous system. These include techniques for silver impregnation of degenerating fibers; autoradiographic technique for studying axonal projections; and somatopetal movement of horseradish peroxidase as a tool for studying connections and neuron morphology. Part IV discusses the interpretation of results from neuroanatomical research techniques and presents examples of the applications of neuroanatomical methods to major problems in physiological psychology.

First multi-year cumulation covers six years: 1965-70.

It has long been recognized that damage to the mammalian central nervous system may be followed by behavioral recovery, but only re cently has close attention been directed to specific factors which may enhance or retard restitution. This is evident in the rapidly growing number of journal articles and scientific paper sessions dealing with "recovery of function," as well as in the publicity given by the popular press to some of the findings in this field. The present text seeks to examine the foundations of brain lesion research, to review recent material on a number of factors which ap pear to contribute to recovery after brain damage, and to present mod els which have been proposed to account for these effects. In order to best accomplish these goals, a number of key workers in these areas were asked to examine and describe research literatures dealing with specific problems or methodological manipulations associated with brain damage and behavior, using their own experiments and those of others to illustrate important points. In addition, significant interpre tive and theoretical issues were to be evaluated in each chapter.

If this were a traditional textbook of neuroanatomy, many pages would be devoted to a description of the ascending and descending pathways of the spinal cord and several chapters to the organization of the sensory and motor systems, and, perhaps, a detailed discussion of the neurological deficits that follow various types of damage to the nervous system would also be included. But in the first draft of this book, the spinal cord was mentioned only once (in a figure caption of Chapter 2) in order to illustrate the meaning of longitudinal and cross sections. Later, it was decided that even this cursory treatment of the spinal cord went beyond the scope of this text, and a carrot was substituted as the model. The organization of the sensory and motor systems and of the peripheral nervous system have received similar coverage. Thus, this is not a traditional text, and as a potential reader, you may be led to ask, "What's in this book for me?" This book is directed primarily toward those students of behavior who are either bored or frightened by the medically oriented texts that are replete with clinical signs, confusing terminology, and prolix descriptions of the human brain, an organ which is never actually seen in their laboratories. I should hasten to add, however, that this text may also serve some purpose for those who read and perhaps even enjoy the traditional texts.

Methods in Psychobiology, Volume 3, Advanced Laboratory Techniques in Neuropsychology and Neurobiology is devoted in large measure to specialized techniques that are widely used in the fields of psychobiology and neurobiology. The experimental methods described form a companion to those presented in Volumes 1 and 2. Many of the procedures presented hinge directly on a mastery of the more rudimentary techniques dealt with in the earlier volumes. The emphasis in the content of this book is on one facet of neurobiology, the mammalian central nervous system. The central or peripheral processes that affect this system in a rat or larger laboratory animal constitute the principal focus of this series. This is due in large part to the enormous amount of research carried out with higher species and the generalizations that, it is hoped, may be drawn to the nervous system of the human. Topics discussed include neuronal connectivity; chemical lesioning of indoleamine pathways; evaluating sensation in animals after lesions, treatment with drugs, electrical stimulation, cooling, or radical changes in environment or development; and sleep in animals.

Most neurobiological research is performed on vertebrates, and it is only natural that most texts describing neuroanatomical methods refer almost exclusively to this Phylum. Nevertheless, in recent years insects have been studied intensively and are becoming even more popular in some areas of research. They have advantages over vertebrates with respect to studying genetics of neuronal development and with respect to studying many aspects of integration by uniquely identifiable nerve cells. Insect central nervous system is characterized by its compactness and the rather large number of nerve cells in a structure so small. But despite their size, parts of the insect eNS bear structural comparisons with parts of vertebrate eNS. This applies particularly to the organization of the thoracic ganglia (and spinal cord), to the insect and vertebrate visual sys tems and, possibly, to parts of the olfactory neuropils. The neurons that make up these areas in insects are often large enough to be impaled by microelectrodes and can be injected with dyes. Added to advantages of using a small eNS, into which the sensory periphery is precisely mapped, are the many aspects of insect behaviour whose components can be quan titized and which may find both structural and functional correlates within clearly defined regions of neuropil. Together, these various features make the insect eNS a rewarding object for study. This volume is the first of two that describe both classic and recent methods for neuroanatomical research on insect eNS.

Connections define the functions of neurons: information flows along connections, as well as growth factors and viruses, and even neuronal death may progress through connections. Knowledge of how the various parts of the brain are interconnected to form functional systems is a prerequisite for the proper understanding of data from all fields in the neurosciences. Clinical Neuroanatomy: Brain Circuitry and Its Disorders bridges the gap between neuroanatomy and clinical neurology. It emphasizes human and primate data in the context of disorders of brain circuitry which are so common in neurological practice. In addition, numerous clinical cases demonstrate how normal brain circuitry may be interrupted and to what effect. Following an introduction into the organization and vascularisation of the human brain and the techniques to study brain circuitry, the main neurofunctional systems are discussed, including the somatosensory, auditory, visual, motor, autonomic and limbic systems, the cerebral cortex and complex cerebral functions.
