Mechanisms of Saccadic Adaptation
The mechanism of saccadic adaptation constitutes a role model for learning in motor systems. The close interconnection between sensory and motor information in eye movements is unique in the human brain. Therefore, control mechanisms of the brain can be studied in detail by determining oculomotor learning. Whereas in the past, the saccadic system has been considered being a stand-alone system fed only by retinal errors of preceding saccades, my research interest focusses on the numerous additional sources of information, which the visuomotor system uses to empower visuomotor learning. These additional sources include temporal and spacial properties of the learning signal as well as inputs from other eye movement systems, e.g. the pursuit system.
