Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Mammalian Vocalization is designed as a broad and comprehensive, but well-balanced book, written from the neuroscience point of view in the broad sense of this term. This well-illustrated Handbook pays particular attention to systematically organized details but also to the explanatory style of the text and internal cohesiveness of the content, so the successive chapters gradually develop a consistent story without losing the inherent complexity. Studies from many species are included, however rodents dominate, as most of the brain investigations were done on these species. The leading idea of the Handbook is that vocalizations evolved as highly adaptive specific signals, which are selectively picked up by the brain. The brain serves as a receptor and behavioural amplifier. Brain systems will be described, which allow vocal signals rapidly changing the entire state of the organism and trigger vital biological responses, usually also with accompanying emission of vocalizations. Integrative brain functions leading to vocal outcome will be described, along with the vocalization generators and motor output to larynx and other supportive motor subsystems. The last sections of the Handbook explains bioacoustic structure of vocalizations, present understanding of information coding, and origins of the complex semiotic/ semantic content of vocalizations in social mammals. The Handbook is a major source of information for professionals from many fields, with a neuroscience approach as a common denominator. The handbook provides consistent and unified understanding of all major aspects of vocalization in a monographic manner, and at the same time, gives an encyclopaedic overview of major topics associated with vocalization from molecular/ cellular level to behavior and cognitive processing. It is written in a strictly scientific way but clear enough to serve not only for specialized researchers in different fields of neuroscience but also for academic teachers of neuroscience, including behavioural neuroscience, affective neuroscience, clinical neuroscience, neuroethology, biopsychology, neurolingusitics, speech pathology, and other related fields, and also for research fellows, graduate and other advanced students, who widely need such a source publication. The first comprehensive handbook on what we know about vocalization in Mammalians Carefully edited, the handbook provides an integrated overview of the area International list of highly regarded contributors, including Jaak Pankseep (Washington State University), David McFarland (Oxford), John D. Newman (NIH ?

Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Ultrasonic Vocalization: Window into the Mammalian Brain, Volume 25, is an exhaustive resource on ultrasonic vocalizations in vertebrates, providing full coverage of all aspects of these vocalizations. The book also demonstrates the usefulness of ultrasonic vocalizations in studies of animal communication, sociobiological states, and in mammalian models of affective disorders, addictions and neurodevelopmental disorders, making it an indispensable resource for researchers using animal models. The book begins with the evolution of vocal communication before discussing mechanisms of ultrasound production, perception and the brain systems involved in emotional arousal that are responsible for the generation of vocalization and emotional states. In addition, the book covers studies of neuroactive agents and sociopsychological conditions that can regulate the outcome of ultrasonic vocalization and provide clues about animals’ internal states. Critically, the book also includes thorough coverage of pharmacological investigations using ultrasonic vocalizations, increasingly being utilized for studies in affective disorders, psychoses, addiction and alcoholism. No other book provides such extensive coverage of this rapidly growing field of study. Represents a multidisciplinary approach that incorporates evolution, communication, behavioral homeostasis, emotional expression and neuropsychiatric dysfunction Provides a systematic review of ultrasonic vocalizations in major groups of rodents widely used in laboratory research Discusses numerous other species across vertebrates that emit ultrasounds

This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: To the majority of biologists, the physiological control of mammalian vocalizations is only a small part of the large field of motor physiology. It is indeed a very specialized part, and the number of scientists dealing with it is relatively small. Still, it is an autonomous subject embracing more than the motor control of the body and is, therefore, by far more complex. Anatomically, essential cerebral structures involved in the control of gross and fine movements of the mammalian body seem to participate in the control of the voice as well. The central control system, however, as well as the larynx (the primary effector organ), possess features not found in the remaining motor system. An example is the perfect synergism of the many muscles which control the m. vocaZis, not to speak of the speed of successions in which this occurs. Furthermore, this muscle, similar to the facial muscles, is segmentally adjustable independently of the joints. The most remarkable feature of the central control area, however, seems to be the effector organ's manifold direct and indirect dependence on the limbic system of the brain. This makes the voice--like no other motor organ (with the partial exception of the facial musculature)--the chief organ for the expression of emotion and the indicator of behavioral states. Except in man, the voice is in dependent of neocortical control. Animal vocalizations are species typical and genetically programmed. Ethologically, they belong to the behavioral class of fixed action patterns.

Available in PDF, EPUB and Kindle. Book excerpt: Why do we think that we can understand animal voices - such as the aggressive barking of a pet dog, and the longing meows of the family cat? Why do we think of deep voices as dominant and high voices as submissive. Are there universal principles governing our own communication system? Can we even see how close animals are related to us by constructing an evolutionary tree based on similarities and dissimilarities in acoustic signaling? Research on the role of emotions in acoustic communication and its evolution has often been neglected, despite its obvious role in our daily life. When we infect others with our laugh, soothe a crying baby with a lullaby, or get goose bumps listening to classical music, we are barely aware of the complex processes upon which this behavior is based. It is not facial expressions or body language that are affecting us, but sound. They are present in music and speech as "emotional prosody" and allow us to communicate not only verbally but also emotionally. This groundbreaking book presents a thorough exploration into how acoustically conveyed emotions are generated and processed in both animals and man. It is the first volume to bridge the gap between research in the acoustic communication of emotions in humans with those in animals, using a comparative approach. With the communication of emotions being an important research topic for a range of scientific fields, this book is valuable for those in the fields of animal behaviour, anthropology, evolutionary biology, human psychology, linguistics, musicology, and neurology.

Available in PDF, EPUB and Kindle. Book excerpt: Neuroendocrine Regulation of Animal Vocalization: Mechanisms and Anthropogenic Factors in Animal Communication examines the underpinning neuroendocrine (NE) mechanisms that drive animal communication across taxa. Written by international subject experts, the book focuses on the importance of animal communication in survival and reproduction at an individual and species level, and the impact that increased production and accumulation of endocrine-disrupting chemicals (EDCs) can have on these regulatory processes. This book discusses sound production, perception, processing, and response across a range of animals. This includes insects, fish, bats, birds, nonhuman primates, infant humans, and many others. Some chapters analyze how neuroactive substances, endocrine control, and chemical pollution affect the physiology of the animal’s perceptive and sound-producing organs, as well as their auditory and vocal receptors and pathways. Other chapters address the recent approaches governments have taken to protect against the endocrine disruption of animal (vocal) behaviors. The book is a valuable resource for researchers and advanced students seeking first-rate material on neuroendocrinological effects on animal behavior and communication. Serves as the most comprehensive cross-taxa study of its kind, revolutionary in its focus on the impacts of EDCs on the processes guiding animal communication Emphasizes the importance of production, perception and processing of acoustic vocalization for survival Analyzes recent governmental policies and protections against the effects of EDCs on humans and wildlife

Book excerpt: Arguably biosonar is one of the ‘eye-opening’ discoveries about animal behavior and the auditory systems of echolocators are front and center in this story. Echolocation by bats has proven to be a virtual gold mine for colleagues studying neurobiology, while providing many rich examples of its impact on other areas of bats’ lives. In this volume we briefly review the history of the topic (reminding readers of the 1995 Hearing by Bats). We use a chapter on new findings in the phylogeny of bats to put the information that follows in an evolutionary context. This includes an examination of the possible roles of Prestin and FoxP2 genes and various anatomical features affecting bat vocalizations. We introduce recent work on the role of noseleafs, ears, and other facial components on the focusing of sound and collection of echoes. ​

Book excerpt: The book aims to integrate our understanding of mammalian societies into a novel synthesis that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a coherent structure that deals initially with the characteristics and strategies of females, before covering those of males, cooperative societies and hominid societies. It reviews our current understanding both of the structure of societies and of the strategies of individuals; it combines coverage of relevant areas of theory with coverage of interspecific comparisons, intraspecific comparisons and experiments; it explores both evolutionary causes of different traits and their ecological consequences; and it integrates research on different groups of mammals with research on primates and humans and attempts to put research on human societies into a broader perspective.

Available in PDF, EPUB and Kindle. Book excerpt: Every coordination within or between animals depends on communication processes. Although the signaling molecules, vocal and tactile signs, gestures and its combinations differ throughout all species according their evolutionary origins and variety of adaptation processes, certain levels of biocommunication can be found in all animal species: (a) Abiotic environmental indices such as temperature, light, water, etc. that affect the local ecosphere of an organism and are sensed, interpreted. (b) Trans-specific communication with non-related organisms. (c) Species-specific communication between same or related species. (d) Intraorganismic communication, i.e., sign-mediated coordination within the body of the organism. This book gives an overview of the manifold levels of animal communication exemplified by a variety of species and thereby broadens the understanding of these organisms.

Available in PDF, EPUB and Kindle. Book excerpt: This open-access book empowers its readers to explore the acoustic world of animals. By listening to the sounds of nature, we can study animal behavior, distribution, and demographics; their habitat characteristics and needs; and the effects of noise. Sound recording is an efficient and affordable tool, independent of daylight and weather; and recorders may be left in place for many months at a time, continuously collecting data on animals and their environment. This book builds the skills and knowledge necessary to collect and interpret acoustic data from terrestrial and marine environments. Beginning with a history of sound recording, the chapters provide an overview of off-the-shelf recording equipment and analysis tools (including automated signal detectors and statistical methods); audiometric methods; acoustic terminology, quantities, and units; sound propagation in air and under water; soundscapes of terrestrial and marine habitats; animal acoustic and vibrational communication; echolocation; and the effects of noise. This book will be useful to students and researchers of animal ecology who wish to add acoustics to their toolbox, as well as to environmental managers in industry and government.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first volume of the bioacoustics series published by the Society for Bioacoustics. This volume provides an overview of the advances and recent topics in acoustic communication in various animals. Most animals produce vibrations and sounds by moving their body parts, including vocal organs. These sounds can be research targets of bioacoustics studies. How animals use these sounds, especially in inter-individual relationships, is the focus of this volume, “Acoustic Communication in Animals”. The authors’ expertise varies from molecular biology, neurobiology to psychology, and human brain imaging. Their research subjects range from invertebrates to humans. Despite the variety of topics, chapters are developed under the consideration of ethology and evolution. Readers will recognize the profundity of the topics in each chapter. In addition, the view and understanding of natural sound sequences produced by animals can vary among different cultures. Research from Japan and regions that have been underrepresented in previous literature can offer new ideas and unique perspectives in the study of bioacoustics. Readers can grasp the progress of this research field in a broad range of species in one book. The book presents multi- and interdisciplinary topics and appeals to researchers and students in fields including psychology, physiology, zoology, ethology, and neurosciences.

It introduces measurable and neurobiologically-informed concepts and language to help professionals and organizations decrease stigma related to mental health and increase awareness of a new paradigm. This new, emerging paradigm moves away from previous language related to mental and psychological health, and moves towards language that focuses on promoting systems resilience and neurological adaptability through measurable neurophysiological mechanisms. It explores human communication patterns through the lens of neurophysiology, systems thinking, the Neurovisceral Integration Model, and attachment frameworks. This book will give people who are in helping professions - coaches, therapists, teachers, first responders - and leaders of all sorts - a new map and vocabulary for understanding mental health in terms of nervous system mechanisms for detecting and creating safety. FEATURES: Provides examples of brain maps (quantitative EEGs) related to issues with Signal Flow Features illustrations of biomechanical principles of nervous system mechanisms for signal transmission and detection A map for using neurophysiology-based language to describe current concepts in psychology, therapy, and mental health.

Available in PDF, EPUB and Kindle. Book excerpt: Bat detector surveys are carried out by ecological consultants, researchers, conservationists and hobbyists. Understanding and categorising non-bat sounds in surveys offers the potential of knock-on benefits for informing development projects (e.g. other important records discovered within a site), as well as the possibility of associated conservation benefits. In recent years the number of people carrying out these surveys and recording calls with bat detectors has grown considerably. These surveys often generate vast amounts of audio recordings, resulting in the heavy workload associated with completing the sound analysis and reporting process. Those carrying out analysis can be distracted, intrigued or delayed owing to the occurrence of recordings that are unfamiliar and not identifiable to them. These recordings can relate to ‘difficult to ID’ bat species, but also, often, sounds not related to bats. This can be especially true when noise triggers such as insects, small mammals or birds look like bat-related noise. Therefore, only knowing what bats sound like is not enough. It is extremely useful to know what other sources of noise look and sound like within the same soundscape. This resource will help bat workers, in whatever environment they are in, to be more confident in recognising, categorising and dismissing other sounds. The book includes a substantial downloadable sound library (.wav format) that readers can listen to by ear or process through sound analysis software. Is That a Bat? also caters for sounds that are also heard by ear alone, in the field, during the hours of darkness. These scenarios often have bat surveyors intrigued or confused as to what they are listening to. Occasionally, knowing what these sounds are could be important, or at the very least, of interest. The first chapter caters for the subject overall, including suggestions from the author as to why the subject matter is of value. It also discusses bat-related calls (including social calls) with a view to offering comparisons against the other sources of sound discussed in separate chapters. Continuing through the book, there are chapters covering the following: small mammals; amphibians; insects; birds; electrical/mechanical noise; and other noise/nuisances. Within each chapter there are sub-sections about bat detector recorded sound, sound by ear, as well as advice on techniques and methods to reduce or increase the likelihood of recording other sounds. The book concludes with associated appendices, including a ‘Problem Solving Key’ to help those encountering an unfamiliar sound to narrow it down to the likely source. With technology advancing at pace, the technical ability of the analyst is of huge importance. With a wider perspective and more knowledge, those responsible for interpreting field encounters can be more confident when making decisions about sources of sound. Apart from that, ‘knowing stuff’ makes the job far more interesting and gives the bat worker a greater appreciation of the natural world within which they are working.
