Figure 1 with 1 supplement
Grand-average traces of the contribution of external stimulus displacements (larger and smaller) and saccades to high-frequency broadband activity in seven regions of interest.
Shading around the grand average waveforms denotes ±1 standard error (between-subjects error variability). ne denotes the number of electrodes per trace and np denotes the number of subjects per …
Figure 1—figure supplement 1
Latencies and magnitudes of external stimulus displacements and saccades.
Each pair of histograms presents data from an individual patient. (a) The latencies of external Displacements (purple) and saccades (green), relative to trial onset. For saccades, the moment of …
Figure 2 with 3 supplements
Significant differences between positive high-frequency broadband (HFB) activity increase following external stimulus displacements (either 1.3° or 3.7°) and positive HFB activity increase following saccades (1.3° to 3.7°).
See Figure 2—figure supplement 1 for the same analysis using only saccades whose onsets were in the range of 300–700 ms post trial-onset. See Figure 2—figure supplements 2 and 3 for a comparison of …

Figure 2—source data 1
Individual electrode data for Figure 2.
Each row describes an electrode, with its SUMA standardized mesh nearest vertex (index, hemisphere and MNI coordinates), region of interest (if assigned), FDR-corrected p value for external displacements greater than saccades, and FDR-corrected p value for saccades greater than external displacements.

Figure 2—figure supplement 1
Significant differences between positive high-frequency broadband (HFB) activity increase following external stimulus displacements (either 1.3° or 3.7°) and positive HFB activity increase following saccades (1.3° to 3.7°), using only saccades whose onsets were in the range of 300–700 ms post trial-onset.

Figure 2—figure supplement 2
Significant differences between positive high-frequency broadband (HFB) activity increase following small external stimulus displacements (1.3°) and positive HFB activity increase following saccades (1.3° to 3.7°).

Figure 2—figure supplement 3
Significant differences between positive high-frequency broadband (HFB) activity increase following large external stimulus displacements (3.7°) and positive HFB activity increase following saccades (1.3° to 3.7°).

Figure 3
Individual electrode traces of the contribution of external stimulus displacements and saccades to the High-Frequency Broadband activity in low vs. high-level sites, sampled in two individual subjects.
Shading around the waveforms denotes ±1 standard error of the regression coefficients (between-trials error variability). Horizontal bars mark response timepoints significantly different from zero …
Figure 4
Blink suppression index versus saccade suppression index across seven visual regions of interest.
The circles depict the ROIs' means and the error bars depict the standard errors of the means. Values greater than 1 were possible since some electrodes registered negative blink- (or saccade-) …

Figure 4—source data 1
Individual electrode data for Figure 4.
Each row describes an electrode, with its SUMA standardized mesh nearest vertex (index, hemisphere and MNI coordinates), region of interest (only electrodes with assigned ROIs participated in this analysis), blink suppression index and saccade suppression index.
