Figure 1.
A typical individual subject's eye movement responses (displacement and velocity) from the lab to each of the 3 main tasks displayed with 3 difference delays (i) Active task with 2 second delay (upper graph), (ii) Passive Task with 4 second delay (middle graph) and (iii) Random Task with 6 second delay (lower graph).
Displacement of the eye uses the left-hand scale and is shown by either the darkest (horizontal) or lightest (vertical) grey. Velocity is shown by the mid-greys (horizontal = darker and vertical = lighter) with the velocity scale depicted on the right-hand side of the graphs.
Figure 2.
The mean (± std) eye velocity 50 ms after target onset (V50) (i.e. prior to visual feedback) (graph A), and mean (± std) latency of the eye movement from target onset (graph B) for all subjects is shown.
Data is displayed according to task (Active, Passive and Random) and delay (2, 4 and 6 seconds).
Figure 3.
a, b and c: The figures display the mean % BOLD signal change for each of the 3 tasks (Active, Passive and Random) for each delay (2, 4 and 6 s) in the ROI.
Figure 3a: shows the medial temporal cortex (V5), the supramarginal gyrus (SMG), and superior parietal lobe (SPL); Figure 3b: presents data for the cerebellum (CBM), and primary visual cortex (V1); Figure 3c: shows data for frontal eye fields (FEF), supplementary eye fields (mid SEF), and dorsolateral prefrontal cortex (DLPFC). The centre of mass for the regions of interest used in the analysis are highlighted within a template brain on either side of the % signal change graph for all figures and brain coordinates are presented using the Montreal Neurological Institute (MNI). T values and significance corrected cluster level P values are also displayed for each ROI.

Figure 4.
A summary diagram to show the areas involved in short-term memory maintenance during predictive smooth pursuit eye movements.
Light grey areas are areas more involved in the reactive tasks, and the darker grey areas are important in both Active and Passive predictable tasks.
