Figure 3.

Modulation of microsaccade rate and direction. A, Transient variations of the potential due to perceptual input change (black line) and attention (green) and resulting threshold variation (red dashed line). B, Microsaccadic directions computed from 2000 runs of the model (raster plot). C, Corresponding rate modulation (blue line) computed from raster plot (where each line represents a single model run). D, Rate difference between cue-congruent and cue-incongruent microsaccades (red line) and bootstrap-based confidence region around the zero difference.
