This research has adapted the phase-lock technique in recording of Continuous Evoked Potentials (CEPs, also referred to as 'steady-state' potentials) for monitoring of the auditory and visual sensory channel engagement and for stimulus parameter-space characterization of the Auditory-Visual Interaction effect (AxV). Sensory interaction was concluded whenever response variations of one sensory channel could be attributed to parameter changes of an additional stimulus, simultaneously presented to another sensory channel. Keywords: Auditory perception, Visual perception, Man machine systems, Evoked potentials, Sensory integration, Audio-Visual interaction, Lock-In Amplifier application, Human steady-state EP. (kt).

This book reviews how we can record the human brain's response to sounds, and how we can use these recordings to assess hearing. These recordings are used in many different clinical situations--the identification of hearing impairment in newborn infants, the detection of tumors on the auditory nerve, the diagnosis of multiple sclerosis. As well they are used to investigate how the brain is able to hear--how we can attend to particular conversations at a cocktail party and ignore others, how we learn to understand the language we are exposed to, why we have difficulty hearing when we grow old. This book is written by a single author with wide experience in all aspects of these recordings. The content is complete in terms of the essentials. The style is clear; equations are absent and figures are multiple. The intent of the book is to make learning enjoyable and meaningful. Allusions are made to fields beyond the ear, and the clinical importance of the phenomena is always considered.

From August 25 - 28, 1978 a conference on averaged evoked po tentials was held at Konstanz, West Germany. Research on human evoked potentials has progressed rapidly in the past decade, and a series of international conferences have served to maintain com munication between active workers in the field. Among the organiza tions that have a tradition of supporting such mUlti-national com munication are the North Atlantic Treaty Organization Scientific Affairs Division, the u.s. Office of Naval Research and the German Research Society (Deutsche Forschungsgemeinschaft). We have been fortunate to have the support of all three. In the early stages of planning, a committee was formed composed of Professors Rudolph Cohen (Konstanz), Otto Creutzfeldt (Goettingen), John Desmedt (Brussels), A.M. Halliday (London), Anthony Remond (Paris) and Herbert Vaughan (New York). A call for papers was circulated as widely as possible, and this committee carried out the difficult task of selecting a limited number of participants from a large number of excellent abstracts. At the same time Professor Cohen of the University of Konstanz was generous enough to shoulder the task of playing host to the conference. His thoughtful arrangements contributed enormously to the comfort of the participants. He and his colleagues also engi neered an ideal ambience for sharing of ideas and observations, while the University of Konstanz generously provided audio-visual support.

The Human Auditory System: Fundamental Organization and Clinical Disorders provides a comprehensive and focused reference on the neuroscience of hearing and the associated neurological diagnosis and treatment of auditory disorders. This reference looks at this dynamic area of basic research, a multidisciplinary endeavor with contributions from neuroscience, clinical neurology, cognitive neuroscience, cognitive science communications disorders, and psychology, and its dramatic clinical application. - A focused reference on the neuroscience of hearing and clinical disorders - Covers both basic brain science, key methodologies and clinical diagnosis and treatment of audiology disorders - Coverage of audiology across the lifespan from birth to elderly topics
