WebWhen looking at a visual stimulus, the eyes make continuous and rapid movements known as saccades. With durations of roughly 150–200 milliseconds for planning and execution (Muir & Richardson, 2005), a saccade directs attention to the visual target and during which information processing is restrained (Pan et al., 2004; Rayner, 1998). WebApr 1, 2002 · As shown in Fig.2 D, the cell's peri-saccadic activity during the initial saccade of this rapid two-saccade sequence is no different from its activity for a single saccade to the same goal (P = 0.44). Thus the …

WebSaccades are rapid shifts of gaze that normally place the line of sight on a desired target with a single smooth movement.
