The objectives of this project are to (1) modify electrophysiological techniques previously developed for dolphins to assess hearing sensitivity in California sea lions (Zalophus californianus), (2) benchmark the techniques using behavioral hearing data from the same individual, and (3) apply the techniques to measure the hearing sensitivity of all available Navy sea lions.

The primary goal of this project is to develop the technology and methods required to make quantitative, repeatable, and interpretable measurements of pinniped hearing sensitivity using averaged evoked potentials recorded from the surface of the head. This effort will advance understanding of marine mammal auditory physiology and provide the tools necessary for the study of population-level and species-level hearing so that noise impacts in marine ecosystems can be better understood. The immediate goals of this project are as follows: (1) transfer available technology from ongoing research with cetaceans to establish an appropriate system for recording auditory evoked potentials in pinnipeds, (2) develop protocols for electrode placement and stimulus presentation that result in optimal evoked potential recordings, (3) measure the hearing sensitivity of individuals from multiple pinniped species using evoked potential methodology, (4) benchmark the evoked potential measures of hearing against standard behavioral measurements obtained for the same individuals, and (5) compare both behavioral and physiological hearing measures obtained for pinnipeds with those obtained under similar conditions for dolphins. Development of standardized procedures and technologies for evoked potential audiometry that are suitable for marine mammal species are necessary to achieve the ultimate goals of understanding species-specific population level variations in hearing sensitivity and to move toward the ability to measure the hearing sensitivity of species for which behavioral methodologies are not applicable (e.g., baleen whales, beaked whales, Antarctic seals). Such information is essential to mitigating the effects of anthropogenic noise in the marine environment and furthering scientific knowledge of the role of acoustics in marine mammal biology, behavior, and ecology.

Attention has been drawn to the subject of how ocean noise affects marine mammals by a series of marine mammal strandings, lawsuits, and legislative hearings, and most recently, the report from the U.S. Commission on Ocean Policy. One way to assess the impact of ocean noise is to consider whether it causes changes in animal behavior that are "biologically significant," that is, those that affect an animal's ability to grow, survive, and reproduce. This report offers a conceptual model designed to clarify which marine mammal behaviors are biologically significant for conservation purposes. The report is intended to help scientists and policymakers interpret provisions of the federal Marine Mammal Protection Act.

Two groups of animals, bats and odontocetes (toothed whales), have independently developed the ability to orient and detect prey by biosonar (echolocation). This active mechanism of orientation allows these animals to operate under low light conditions. Biosonar is a conceptual overview of what is known about biosonar in bats and odontocetes. Chapters are written by bat and odontocetes experts, resulting in collaborations that not only examine data on both animals, but also compare and contrast mechanisms. This book provides a unique insight that will help improve our understanding of biosonar in both animal groups.

Fuctional Neurology for Practitioners of Manual Medicine takes the reader from the embryonic beginnings of the nervous system, through the biochemistry of receptor activation and on to the functional systems of the nervous system. Concepts, relationships and scientific mechanisms of the nervous system function are covered, and this aids the practitioner in developing their clinical approach to a wide variety of patient presentations. The text is fully referenced, which allows the reader to immediately apply the concepts to practice situations. New for this edition are new chapters on pain (including headache) and theoretical evidence, plus extensive electronic resources supporting the text. Utilizes our understanding of how the nervous system works in the treatment of a variety of clinical conditions Demystifies the clinical results seen in the practice of Functional Neurology and scientifically validates its clinical success Addresses function rather than pathology, allowing the reader to gain a firm understanding of the neurological processes seen in health and disease Contains clinical cases which are designed to be read and answered before starting the chapter to allow the reader to gauge their current state of knowledge ‘Quick Facts’ introduce new concepts or allow rapid review of information already presented in the text in a brief and succinct manner Contains a detailed overview of the concepts relating to our understanding of the development of emotion to demonstrate the link between physical health and the mind Contains abundant references to support controversial concepts Contains new chapters on theoretical evidence and the management of pain (including headache) Contains a wide range of additional case studies, ‘clinical conundrums’ and key questions and answers for each topic Bonus DVD contains fully searchable text, a downloadable image bank, brain dissection and video clips of the manipulative techniques and examination procedures found within the volume plus 200 multiple choice questions
