From: Sustained spatial attention accounts for the direction bias of human microsaccades
Overall microsaccade-directional modulation (see “Material and Methods”). (A) The microsaccade-directional modulations by attended location (abscissae) plotted against microsaccade-directional modulations by saccade goal (ordinates). Each dot represents one subject. For both attended location and saccade goal, a positive modulation indicates a microsaccade-directional bias towards the respective location. Dotted vertical and horizontal lines indicate the zero line of abscissa and ordinates, respectively. Dashed line shows the unity line. Arrows on horizontal and vertical axes indicate the median of abscissa and ordinates among all subjects, respectively. Filled symbols indicate the median is significantly different from zero; while open symbols, not. (B) The microsaccade-directional modulation by attention for congruent-cue trials (abscissa) plotted against that for incongruent-cue trials (ordinates). Lines and symbols are similarly defined as in A).
