During September 10-14, 1984, we held a study Workshop on the Lake Arrowhead convention middle, California, bringing togeth­ er leaders within the box of digital spatial sensors for the blind from the psychology, engineering, and rehabilitation components. Our aim used to be to interact those teams in dialogue with each other approximately clients for the way forward for digital spatial sensing, within the gentle of rising applied sciences and the expanding sophistica­ tion of behavioral learn concerning this box. The papers during this ebook supply an replace on a number of of the major learn traditions in thi s fi e 1 d. Broader overvi ews are provi ded within the paper via Brabyn, and in our historic review, ultimate remark and the Introductions to every part. In a box as advanced as this, a few overlap of dialogue is fascinating and the reader with a major curiosity during this box is suggested to pattern a number of reviews. This quantity, and the convention on which it truly is established, got the help of many folks and agencies. The medical Affai rs Divi sion of the North Atl antic Treaty association sup­ ported the convention as a part of their software of complex examine Workshops, and the technological know-how and know-how to assist the Handicapped application of the nationwide technology origin supplied extra significant monetary help. the guts for Social and Behavioral Sciences learn of the collage of California, Riverside supplied monetary in addition to significant logistical support.

Cerebral Cortex: Neurodegenerative and Age-Related Changes in Structure and Function of Cerebral Cortex

This quantity of Cerebral Cortex is devoted to Sir John Eccles, who was once an energetic member of the advisory board for the sequence until eventually his demise in might 1997. His enter as to what themes can be lined in destiny volumes of this sequence might be sorely overlooked. the current quantity is anxious with neurodegenerative problems and age­ comparable adjustments within the constitution and serve as of the cerebral cortex, a subject matter that has attracted expanding curiosity as durability and the variety of elderly members within the inhabitants bring up.

Alcoholism and Drug Dependence: A Multidisciplinary Approach

It truly is for me, as President of the Merseyside Lancashire & Cheshire Council on Alcoholism, a sign privilege to put in writing a short foreword to those court cases of the 3rd foreign convention on Alcoholism and Drug Dependence. in the course of the week specialists, from internationally, in all these disciplines that have a contribution to make to the answer of the issues of alcoholism and drug dependence, surveyed contemporary advances in our wisdom of the aetiology, epidemiology, early reputation, administration, and the social and commercial implications of those dual scourges of the modern scene.

Relatively little knowledge exists regarding the basic mechanisms of human mobility. The mechanical process of locomotion has been studied by those interested in limb prostheses, but that research does not address the more complex sensory and cognitive-related aspects of the problem. As a result, researchers have little basic knowledge to use as a starting point when designing and evaluating mobility aids for the blind. What are the essential components of information needed for mobility? What spatial cues does a sighted person rely on for maintaining a safe course through the environment?
