Information Processing Underlying Gaze Control book cover

Information Processing Underlying Gaze Control

This volume summarizes recent advances in the fast growing field of information processing underlying gaze control. Gaze control is a valuable model for addressing basic questions on the functional properties of the central nervous system using the latest anatomical and electrophysiological techniques and is therefore an important area of research across the disciplines.

The book is based on a workshop which drew together leading researchers to exchange information on the computational properties of neuronal circuits underlying gaze control. The relative ease with which the appropriate sensory stimuli and the resulting behavioral responses can be defined and measured has resulted in a great amount of information on the neuronal networks which generate and control eye and head movements. However, although clear definitions for the different steps in this computational processing have emerged, the neuronal and molecular mechanisms at play are far from being elucidated. Furthermore, the relatively recent discovery that neurons have complex intrinsic membrane mechanisms which endow them with non-linear integrative properties has opened a new branch of gaze physiology, but has also further complicated the issue.

This volume, therefore, provides a state-of-the-art picture of the situation, giving special emphasis to the relatively new research areas. The seven sections each include a comprehensive overview from anatomical, electrophysiological, behavioral and modelling aspects.

Audience
For neuroscientists, neurologists, physiologists and others with an interest in gaze control.
