A collection of contemporary work in various areas of eye-movement research, with an emphasis on physiological aspects, emerging from the Sixth European Conference on Eye Movements, organized at the Laboratory of Experimental Psychology of the U. of Leuven, Belgium, September 1991. The contribution are divided into six sections: saccadic eye movements; smooth pursuit and motion perception; eye movements in pathology and clinical settings; neurophysiology of eye movements; optokinetic nystagmus; and methods.
