Abstract

Active vision integrates the information coming, through the retina, from the outside world with that gener- ated internally by the brain, especially by eye movements (saccades). We investigate the influence that the eyes motor con- trol might play on visual search. Thirteen cerebellar patients and twenty-five healthy subjects performed a high cognitively demanding task (Trail Making Test), we correlated the performance of eye motor control with the abilities to perform the task efficiently, and we found a strict correlation between the two factors on patients. The experimental evidence supports an indirect role of the cerebellum on cognitive performance due to noise feedback.
