Research Areas

Self-calibration of the oculomotor system

The visual system is highly specialized to provide far reaching three-dimensional information with high definition. For an active exploration of the ambient scene, subjects make rapid eye movements, called saccades, which shift the direction of gaze and the retinal area of highest resolution from one target of interest to another. Saccades are so brief that the visual feedback is not completely processed until the saccade is already finished and furthermore, the sensory input is actively suppressed by the visual system during saccades. Thus the saccadic motor command has to be prepared reliably in advance to accurately aim the fovea at a new target. Over time, the mechanical properties of the oculomotor plant are subject to alterations that evoke erroneous saccades based on the obsolete motor command. For this reason the oculomotor system is undergoing a continuous process of self-calibration to adapt the new requirements. Experimentally, I investigate this process using the paradigm of saccadic adaptation. The main focus of my research is the employed reference frame in adaptation and the system's learning parameter.
