From: Dynamic modulation of the perceptual load on microsaccades during a selective spatial attention task
The temporal dynamics of the microsaccade directional congruency and the modulations of perceptual load on the microsaccade directional congruency during different time periods. (A–C,E–G) Temporal comparison of the directional congruency ratios between the easy (blue) and hard (pink) tasks for monkeys G and N. The horizontal black dashed lines represent a y-axis value of 0.5 and indicate no microsaccade directional bias toward the indicated location. The black lines at the bottom of each plot denote the periods in which the directional congruency from the easy and hard tasks differed significantly (p < 0.05, Student t test). The gray rectangles are defined as in earlier figures. (D,H) Measures of the perceptual load modulation on the overall congruency of the microsaccade direction during the four periods. The top panels depict the average directional congruency in the easy (blue) and hard (pink) tasks during the four periods. The bottom panels demonstrate the DMI ratios of the direction congruency within the four time periods. The figure conventions are the same as the previous figures.
