This book reviews recent research on the ability of human listeners to discern changes in the shape of complex acoustic spectra--what is known as auditory profile analysis. It also discusses in a systematic way issues surrounding the discrimination of a change in acoustic intensity and the physiological mechanisms responsible for these discrimination processes. The author concludes with two new theories that provide a way of understanding more complex auditory skills, such as those involved in listening to music and speech. This book will be of interest to psychoacousticians, psychophysicists, physiological psychologists, and experimental psychologists.

This book brings together recent research on the ability of human listeners to discern changes in the shape of complex acoustic spectra. It systematically discusses issues surrounding the discrimination of a change in acoustic intensity and the physiological mechanisms responsible for this process. The book also proposes two new theories which attempt to explain spectral shape discrimination on the basis of more elementary auditory processes. The research described here is helping scientists gain a better understanding of auditory skills such as those involved in listening to music and speech.

This book appears at a time when molecular cytogenetics is positioned to make a significant impact upon evolutionary studies, enabling problems of chromosomal structure and change to be critically assessed. It is an up-to-date and comprehensive survey of the cytogenetics of a major class of animals, including all three amphibian orders, with chapters authored by international leaders in the field.Amphibian Cytogenetics and Evolution will be of interest to classical and molecular cytogeneticists, systematicists, evolutionary biologists, herpetologists, and anyone using amphibians in genetic research.- Offers the only current and comprehensive survey of amphibian cytogenetics- Gives authoritative and in-depth coverage of topics of present interest- Reviews general cytogenetic topics- Presents new insights into evolutionary changes in chromosome structure and amphibian phylogeny and relationships including: Phylogenetic analysis of chromosome data, Current techniques of cytogenetic analysis, Examination of all three amphibian orders

Originally published in 1976, this introduction to hearing was intended to provide a sufficient introduction to each of several subareas of hearing so that the serious student can read the more advanced treatments with greater appreciation and understanding. It was intended for upper graduate and graduate students. It assumes some mathematical sophistication – calculus for example, but there is some review of more basic concepts, such as logarithms. There is also a brief treatment of the necessary material from the different disciplines – physics, physiology, psychology, anatomy and mathematics – that a student of hearing will need to know.

Some 300 species of amphibians inhabit North America. The past two decades have seen an enormous growth in interest about amphibians and an increased intensity of scientific research into their fascinating biology and continent-wide distribution. This atlas presents the spectacular diversity of North American amphibians in a geographic context. It covers all formally recognized amphibian species found in the United States and Canada, many of which are endangered or threatened with extinction. Illustrated with maps and photos, the species accounts provide current information about distribution, habitat, and conservation. Researchers, professional herpetologists, and anyone intrigued by amphibians will value North American Amphibians as a guide and reference.

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.
