Interactions between saccades and smooth pursuit eye movements in marmosets
Animals use a combination of eye-movements to track moving objects in the visual world. The different movement types need to coordinate for successful tracking, requiring interaction between the systems involved. Here, we study such interaction between the saccades and smooth pursuit eye movement system in marmosets. Using single target pursuit, we show that saccades cause an enhancement in pursuit following the saccades. Using two-target task, we show that this enhancement in pursuit is selective towards target motion of the target selected by the saccade, irrespective of any biases in pursuit prior to the saccade. Together, our experiments highlight the similarities in the functioning of saccade and smooth pursuit eye movement systems across primates.
