Hearing – From Sensory Processing to Perception presents the papers of the latest “International Symposium on Hearing”, a meeting held every three years focusing on psychoacoustics and the research of the physiological mechanisms underlying auditory perception. The proceedings provide an up-to-date report on the status of the field of research into hearing and auditory functions. The 59 chapters treat topics such as: the physiological representation of temporal and spectral stimulus properties as a basis for the perception of modulation patterns, pitch and signal intensity; spatial hearing and the physiological mechanisms of binaural processing in mammals; integration of the different stimulus features into auditory scene analysis; physiological mechanisms related to the formation of auditory objects; speech perception; and limitations of auditory perception resulting from hearing disorders.
The auditory processing of complex signals is not yet fully understood making a clearer insight into auditory system processes worth aspiring to. One approach for this purpose is to gain a better understanding of the relations between physical parameters and hearing sensations by means of psychoacoustics. Suitable measures such as loudness help to characterize the perception of sound leading to more sophisticated loudness models which could be useful in optimizing hearing devices such as cochlear implants. The scope of this thesis therefore is the suprathreshold perception of sounds with different spectral, temporal and spatial content in normal-hearing listeners and cochlear implant users. Among others, this covers the applicability of categorical loudness scaling as a fast procedure to assess partial loudness as well as binaural and spatial hearing in cochlear implant users in a free-field measurement setup providing realistic spatial cues.
The International Symposium on Hearing is a prestigious, triennial gathering where world-class scientists present and discuss the most recent advances in the field of human and animal hearing research. The 2015 edition will particularly focus on integrative approaches linking physiological, psychophysical and cognitive aspects of normal and impaired hearing. Like previous editions, the proceedings will contain about 50 chapters ranging from basic to applied research, and of interest to neuroscientists, psychologists, audiologists, engineers, otolaryngologists, and artificial intelligence researchers.
Rapidly growing interest in the role of organic cation transporters (OCTs) and plasma membrane monoamine transporter (PMAT) in central monoamine homeostasis makes this book especially timely, given its thematic alignment with the role of OCTs and PMAT in CNS. This book discusses latest insights into the field laying an emphasis on health, disease and therapeutics. The chapter, “General Overview of Organic Cation Transporters in Brain”, of this book is available open access under a CC BY 4.0 license at link.springer.com
Advances in Lipid Research, Volume 6 provides information pertinent to brain cholesterol and myelin lipids. This book reviews the various aspects of the physiology, chemistry, and biochemistry of lipids. Organized into seven chapters, this volume begins with an overview of the separation of lipoproteins and discusses lipid metabolism in microorganisms. This text then provides a discussion of lipid metabolism in mycoplasmas. Other chapters consider the various aspects of metabolism of the lipid quinones and explore the relationship between lipids and atherosclerosis as a continuing source of biochemical, medical, and nutritional interest. This book discusses as well a comparative aspect of the development of atherosclerosis and explains the chemistry of bile acids. The final chapter deals with the aspects of steroid separations as well as with regard to separation of other metabolites that may influence lipid metabolism. This book is a valuable resource for biologists, biochemists, scientists, and research workers.
Most animal communication has evolved and now takes place in the context of a communication network, i.e. several signallers and receivers within communication range of each other. This idea follows naturally from the observation that many signals travel further than the average spacing between animals. This is self evidently true for long-range signals, but at a high density the same is true for short-range signals (e.g. begging calls of nestling birds). This book provides a current summary of research on communication networks and appraises future prospects. It combines information from studies of several taxonomic groups (insects to people via fiddler crabs, fish, frogs, birds and mammals) and several signalling modalities (visual, acoustic and chemical signals). It also specifically addresses the many areas of interface between communication networks and other disciplines (from the evolution of human charitable behaviour to the psychophysics of signal perception, via social behaviour, physiology and mathematical models).

Could we understand, in biological terms, the unique and fantastic capabilities of the human brain to both create and enjoy art? In the past decade neuroscience has made a huge leap in developing experimental techniques as well as theoretical frameworks for studying emergent properties following the activity of large neuronal networks. These methods, including MEG, fMRI, sophisticated data analysis approaches and behavioral methods, are increasingly being used in many labs worldwide, with the goal to explore brain mechanisms corresponding to the artistic experience. The 37 articles composing this unique Frontiers Research Topic bring together experimental and theoretical research, linking st...
The major reference work for a rapidly advancing field synthesizes central themes, reports on current findings, and offers a blueprint for future research. Scientists' attempts to understand the physiology underlying our apprehension of the physical world was long dominated by a focus on the individual senses. The 1980s saw the beginning of systematic efforts to examine interactions among different sensory modalities at the level of the single neuron. And by the end of the 1990s, a recognizable and multidisciplinary field of "multisensory processes" had emerged. More recently, studies involving both human and nonhuman subjects have focused on relationships among multisensory neuronal ensembl...
