This volume contains the proceedings of a work­ shop entitled "Physiological and Pathological Aspects of Eye Movements" held at the Pont d'Oye Castle, Habay-Ia-Neuve, Belgium, March 27-30 1982. The meeting was sponsored by the European Communi­ ties. It brought together specialists of oculomotricity mainly from Europe but also from North-America. With such actions, the Communities want to encourage inter­ national and multidisciplinary contacts between re­ searchers of a particular field. Oculomotor neuroscien­ tists, for quite a long time, have developed such con­ tacts. This cooperation - this is not so common in biological research - embodies various approaches, from basic mechanisms to behavioral studies, but also this applied science that medicine is or should be. Many basic discoveries about eye movement mechanisms, made with the help of human of animal subjects, have found rapid medical applications in neurology, neuro­ ophthalmology or otolaryngology. This is illustrated in this book by the fact that results obtained on rats or cats are interspersed with reports of clinical in­ vestigations. The workshop was mainly focused onto three themes: (a) eye and head movements in man, (b) visuo-vestibular interaction and (c) eye-head coordination. In each theme, one or more "review" papers were included. In addition, most of the oral presentations or posters on display mainly contained unpublished material.
