            Abstract

            Despite their relevance for locomotion and social interaction in everyday situations, little is known about the cortical control of vertical saccades in humans. Results from mi-crostimulation studies indicate that both frontal eye fields (FEF) contribute to these eye movements. Here we present a patient with a damaged right FEF, who hardly made ver-tical saccades during visual exploration. This finding suggests that for the cortical control of exploratory vertical saccades, integrity of both FEF is indeed important.
