Coupling Between Adaptation of Saccadic Eye Movements and Visuo-spatial Perception and Attention Processes: a Behavioural Study in Humans.
This research aims to highlight the key roles of the cerebellar and cortical fronto-parietal networks in the coupling of eye movements with visual perception and visuo-spatial attention.
