Role of the rostral superior colliculus in gaze anchoring during reach movements (original) (raw)

This research investigates the role of the rostral superior colliculus (rSC) in gaze anchoring during reach movements in primates. Findings indicate that rSC neurons exhibit significant activity increases during reaching, particularly when these movements are preceded by saccades, thus demonstrating a link between visual fixation and reach execution. Despite examining various parameters related to movement kinematics, none showed a strong correlation with neuronal activity increases, highlighting the rSC's role as a crucial neural substrate for eye-hand coordination.
