Upper: Example time series from a visual target and the corresponding eye movement during a smooth pursuit of this target. From \citet{Barnes_2008}, Bottom: Diagram of cerebral areas thought to be involved in the production of the smooth pursuit mechanism. Outside of each box, the name of the area is shown and the proposed associated function is written inside the box. The signal from the eyes should enter into the V1/MT box and the command to move the eyes should originate from the 'Motoneuron' box. V1: Primary visual cortex; MT: Middle Temporal cortex; MST: Middle Superior Temporal cortex; NRTP: nucleus reticularis tegmentis pontis; DLPN: dorsolateral pontine nucleus; BS: brainstem.
