Information Processing Underlying Gaze Control

Information Processing Underlying Gaze Control covers the proceedings of the Satellite Workshop to the 16th European Neuroscience Association. The book presents materials concerning the computational properties of neuronal circuits underlying gaze control. The book contains 44 papers, which are organized into seven sections. The first section deals with the morphology and physiology of extraocular motor nuclei. Section II tackles the anatomo-functional organization of the saccadic system, and Section III covers the vestibular and otolithic systems. Section IV discusses the optokinetic and smooth pursuit systems, while Section V talks about other sensory systems involved in the control of oculomotor function. Section VI covers the role of cerebellum in the genesis and control of eye movements, and Section VII tackles the coordination of eye, head, and body movements. The text will be of great use to researchers who have an interest in gaze control.
