Contributions to Sensory Physiology: Volume 4 presents a theory about the physiological basis of sensation. It discusses some research made in microscopic anatomy and psychophysics. It addresses the functional significance and physiological mechanisms of the sensory systems. Some of the topics covered in the book are the visual analogs in somesthesis; psychophysical studies of temperature sensitivity; functions of the skin; pathophysiology of the fluid systems of the inner ear; function of the endolymphatic sac; endolymph-perilymph fistulate; and chemistry of the inner ear fluids. The function of the cochlear aqueduct is covered. The perilymph channels are discussed. The text describes the anatomical aspects of the cochlear nucleus and superior olivary complex. A study of the bilaterally innervated cell groups is presented. A chapter is devoted to the medial nucleus of the trapezoid body. Another section focuses on the neurophysiology of nuclei peripheral to the S-segment. The book can provide useful information to scientists, veterinaries, students, and researchers.

Contributions to Sensory Physiology: Volume 5 presents a theory about the physiological basis of sensation. It discusses some research made in microscopic anatomy and psychophysics. It addresses the functional significance and physiological mechanisms of the sensory systems. Some of the topics covered in the book are the simple cells of the striate cortex; the concept of a receptive field; definition of a unimodal simple cell; inhibitory components in the receptive field; stimulus contrast and mean level of luminance; specificity of inhibitory zones; and experimental procedures for recording average response histogram. The relation and possible importance of taste bud cells are covered. The comparison of foliate, vallate, and fungiform buds are discussed. The text describes the nature of taste receptor sites. A study of the location of receptor sites on taste cells is presented. A chapter is devoted to the mechanochemical model of taste excitation. Another section focuses on the proposals for molecular specificity. The book can provide useful information to scientists, doctors, students, and researchers.

Contributions to Sensory Physiology, Volume 6 covers theories and research about the physiological basis of sensation. The book starts by describing cutaneous communication, including topics about the mechanoreceptive systems in the skin, the temporal relations of the stimuli, and pattern generation and its recognition by the skin. The book then discusses the effects of environments, such as transneuronal degeneration and stimulus deprivation, on the development in the sensory systems. The across-fiber pattern theory and the electrophysiological analysis of the echolocation system of bats are also considered. The book further tackles coding in the auditory cortex and the psychophysics and physiology of the lateralization of transient stimuli. Anatomists and psychophysicists will find the book invaluable.

Contributions to Sensory Physiology, Volume 7, was published with two principal objectives in mind: (1) to bring together reports of current research on all of the sensory systems; and (2) to provide an opportunity for the scientist studying a sensory system to give a detailed account of a series of experiments or to present, at some length, a theory about the physiological basis of sensation. The book contains six chapters and opens with a summary of neuroanatomical studies which show that the cochlear nucleus is the origin of several distinct fiber pathways which have differing fiber diameters, routes, and terminations in more central nuclei of the auditory system. Subsequent chapters deal with the optic chiasm of the vertebrate brain; the morphological basis of orientation selectivity; visual control of movement; visual functions in monkeys following removal of visual cerebral cortex; and subdivisions in sensory systems. It is the hope of the editor and publisher that this serial publication will provide better communication among those who study sensory systems and that it will also be a valuable source of information for scientists from other fields who occasionally seek a representative sample of research that is being done in this important area of physiology rather than just a summary.

Contributions to Sensory Physiology, Volume 8 is a collection of scientific essays that resulted from experiments made in the field of sensory systems. One of the focuses of the study is the superior colliculus, or optic tectum. Optic tectum is responsible for the start of orienting responses to visual stimuli. The layered structure inside the optic tectum is vital to understand the neural basis of its sensorimotor transformations. A chapter of the book shows that some specific rules govern critical developmental actions, such as proliferation, migration, differentiation, cell death, and formation of intercellular connections. The article reviews the ontogenetic sequence by which layers form in the lateral geniculate nucleus. Different classes of axons are also covered in the text. The temporal summation in audition is likewise demonstrated. A section of the volume discusses extensively the central auditory system. The book will serve as a good reference for doctors, veterinarians, neurologists, students, and researcher in the fields of anatomy.

Contributions to Sensory Physiology discusses a theory of the physiological basis of sensation. It describes and illustrates the cellular pattern of the neuro-epithelium, focusing on sensory cells, neural structures, and fluid spaces of the organ of Corti. The book shows that the simultaneous use of light, phase contrast, and electron microscopy generates a better image. It discusses the functional parts of the vestibular and lateral line organs. The text describes the structure and organization of receptors. The structure of the cupula and otolithic membranes are also explained. Complex types of stimulation are examined in detail. The vestibular system is discussed in full. The electrophysiological analysis of the monkey''s eyes is defined as well as the methods that are being used to examine the primate vision. A chapter of the book focuses on the vision in intermittent light. The book will provide useful information to veterinarians, anatomists, students, and researchers in the field of ophthalmology.

Contributions to Sensory Physiology: Volume 2 presents the scientific research on the sensory systems. It discusses the physiological basis of sensation. It addresses the evolution of vertebrate hearing. Some of the topics covered in the book are the origins of neocortex; the differentiation of sensory thalamo-cortical systems in early phases of mammal evolution; the predominance of the auditory system in carnivore; effects of brain stem lesions on the normal prepotency of sound; the logarithmic intensity function of single peripheral units; and sensory neocortex and the evolution of intelligence. The organization of somatic central projections is covered. The pure convergent cortical projections are discussed. The text describes the Weber function and Fechner''s conjecture. A study of the human somesthetic intensity function is presented. A chapter is devoted to the peripheral nerve responses. Another section focuses on the physical correlate theory of perception of intensity. The book can provide useful information to doctors, neurologists, students, and researchers.

nerve; subsequently, however, they concluded that the recordings had been from aberrant cells of the cochlear nucleus lying central to the glial margin of the VIII nerve (GALAMBOS and DAVIS, 1948). The first successful recordmgs from fibres of the cochlear nerve were made by TASAKI (1954) in the guinea pig. These classical but necessarily limited results were greatly extended by ROSE, GALAMBOS, and HUGHES (1959) in the cat cochlear nucleus and by KATSUKI and co-workers (KATSUKI et at. , 1958, 1961, 1962) in the cat and monkey cochlear nerve. Perhaps the most significant developments have been the introduction of techniques for precise control of the acoustic stimulus and the quantitative analysis of neuronal response patterns, notably by the laboratories of KIANG (e. g. GERSTEIN and KIANG, 1960; KIANG et at. , 1962b, 1965a, 1967) and ROSE (e. g. ROSE et at. , 1967; HIND et at. , 1967). These developments have made possible a large number of quanti­ tative investigations of the behaviour of representative numbers of neurons at these levels of the peripheral auditory system under a wide variety of stimulus conditions. Most of the findings discussed herein have been obtained on anaesthetized cats. Where comparative data are available, substantially similar results have been obtained in other mammalian species (e. g. guinea pig, monkey, rat). Certain significant differences have been noted in lizards, frogs and fish as would be expect­ ed from the different morphologies of their organs of hearing (e. g.
