Fig. 8.

LFP modulations during microsaccadic suppression. A and B are formatted similarly to Fig. 3, except that LFP modulations are plotted around a sample electrode track near visual (A) or visual motor neurons (B). There was no evidence of a reduced LFP-evoked response for trials with grating onset after microsaccades (faint colors). If anything, the peak evoked response and the latency to evoked response were stronger and shorter, respectively (see Fig. 9). This effect was not explained by an intrinsic perimicrosaccadic modulation of LFP (see Figs. 9A and 10), but it is consistent with an additional movement-related modulatory signal associated with saccade execution that influences stimulus-evoked spiking activity. Error bars denote SE. For the visual track (A), n ≥ 113 trials per spatial frequency on no-microsaccade trials (black), and n ≥ 25 trials per spatial frequency on microsaccade trials (gray). For the visual motor track (B), n ≥ 140 trials per spatial frequency on no-microsaccade trials (black), and n ≥ 12 trials on microsaccade trials (gray).
