Abstract (English)

Saccadic eye movements are responsible for bringing relevant parts of the visual field onto the fovea for detailed analysis. Since the retina is physiologically unable to deliver sharp images at very high transsaccadic speeds, the visual system minimizes the repercussion of the blurry images we would otherwise perceive during transsaccadic vision by reducing general visual sensitivity and ...


Translation of the abstract (German)

Bereits 75 ms vor Beginn einer sakkadischen Augenbewegung reduziert sich die visuelle Sensitivität deutlich, obwohl die Stimuli zur dieser Zeit auf eine stabile Retina projiziert werden (sakkadische Suppression). In einer event-related fMRI-Studie wird die BOLD-Antwort auf vier periphere Gabor-Reize untersucht. Die Reize wurden kurz vor Beginn einer Sakkade für 8 ms präsentiert. Die BOLD-Antwort ...
