A collection of contemporary work in various areas of eye-movement research with an emphasis on physiological aspects is presented in this book. The contributions are divided into six sections: I. saccadic eye movements; II. smooth pursuit and motion perception; III. eye movements in pathology and clinical settings; IV. neurophysiology of eye movements; V. optokinetic nystagmus; and VI. methods. This volume provides updated information on the most recent research on eye movements carried out mainly in Europe.
