Vision and Cerebellum: Evaluating the Influence of Motor Control on Cognitive Execution through Multiscale Wavelet Entropy

Active vision integrates the information coming, through the retina, from the outside world with that generated internally by the brain, especially by eye movements (saccades). We investigate the influence that the eyes motor control 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.
