Fig. 7: Sub-threshold micro-stimulation applied during the late fixation period biased choice.
a The proportion of choices directed toward the stimulation site target in stimulation condition vs. non-stimulation control condition across the 3 menus. Purple, green, and blue denote when 1st, 2nd, and 3rd value ranking targets were located at the stimulation site, respectively. The dashed line represents the line of unity. b Difference in the proportion of saccades directed toward the stimulation site under stimulation condition minus non-stimulation condition. All the 72 blocks in stimulation experiments were included. Wilcoxon signed-rank test, two-sided, from left to right, P = 3.2 × 10−10, 8.7 × 10−8, 0.90, 1.2 × 10−6, 0.28, and 1.3 × 10−4, respectively. Source data are provided as a Source data file. For the boxplots, on each box, the central mark is the median, the edges of the box are the 25th and 75th percentiles, and the whiskers extend to the most extreme data points that the algorithm considers not to be outliers. Outliers are data points that are larger than Q3 + 1.5 × (Q3 – Q1) or smaller than Q1 – 1.5 × (Q3 – Q1), where Q1 and Q3 are the 25th and 75th percentiles, respectively.
