Our perceptual system tends to associate higher-pitched sounds with upper spatial positions and smaller visual sizes, and lower pitched-sounds with lower positions and bigger visual sizes. This processes, known as crossmodal correspondences or crossmodal associations, emerges consistently and almost universally. The cognitive, developmental and neural mechanisms underlying these crossmodal correspondences were investigated in the present doctoral dissertation. In the present work, I studied how the crossmodal associations between auditory and visuospatial stimuli modulates cognitive processes in infancy and maturity. In addition, I investigated the impairments in auditory processing in population with visuospatial disorders. The presence of crossmodal associations between pitch and spatial elevation are solid in adults (see Spence, 2011), and can be observed in the ability of certain auditory stimuli to modulate visuospatial attention (e.g., rising sounds facilitate the detection of a visual stimuli in upper areas in the external space). However, it seems that higher- pitched sounds or sounds with rising frequencies have higher inherent spatial properties than lower-pitched or falling frequency sounds. These spatial properties of the sound could modulate the perceptual system and facilitate the detection of visual objects in superior positions of the visual field. We found evidence of the existence of crossmodal correspondences between auditory and visuospatial dimensions also in prelinguistic infants, at the age of 6 months. We observed that 4-month-old infants have not developed yet the mechanisms that facilitate audiovisual associations. This pattern of results suggests that the experience with the physical world and/or further maturation is needed to fully develop certain audiovisual crossmodal associations. Finally, in Study 3, I observed that patients with NLD, that show impairments in visuospatial skills, show a deficit in pitch-related tasks. These evidences could suggest that auditory and visuospatial processes share common mechanisms in some stages of the perceptual processing, that is, for example, that the impairment in visuospatial skills could disrupt the auditory processing.

Harmony is an integral part of our auditory environment. Resonances characterised by harmonic frequency relationships are found throughout the natural world and harmonic sounds are essential elements of speech, communication and, of course, music. Providing neurophysiological data and theories that are suitable to explain the neural code of pitch and harmony, the author demonstrates that musical pitch is a temporal phenomenon and musical harmony is a mathematical necessity based on neuronal mechanisms. Moreover, he offers new evidence for the role of an auditory time constant for speech and music perception as well as for similar neuronal processing mechanisms of auditory and brain waves. Successfully relating current neurophysiological results to the ancient ideas of Pythagoras, this unique title will appeal to specialists in the fields of neurophysiology, neuroacoustics, linguistics, behavioural biology and musicology as well as to a broader audience interested in the neural basis of music perception.

Research in music is a multidisciplinary matter. Experts from very different fields in science report the most recent data from their own research and thereby show today's knowledge concerning music and neuropsychological sciences. This includes the developing and adult brain, neurological and psychiatric diseases as well as the battery of the most recent development in brain imaging techniques. This book offers an excellent introduction to new scientific efforts in understanding both neuronal and psychic mechanisms when listening to or performing music.

Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Ion channels generate bioelectricity. Recent findings have documented the biophysical properties, the structure, assembly and regulation, and function and dysfunction of nonclassical nervous system ion channels. This book reviews nonclassical ion channel research, ranging from the basic biology, structure, regulations to their functions not only in normal physiology but also neurological disorders, using a variety of cutting-edge techniques and novel animal models.
