Fig. 3: Burst duration is reduced during drawing in comparison to the rest interval.

Single trials, distributions, mean and standard deviation of the mean burst duration are plotted for the different conditions and intervals (blue = free drawing without stimulation, draw: −0.624 arbitrary units (arb. units) ±0.117 (mean ± standard deviation), n = 149, rest: −0.533 arb. units ±0.165, n = 164; red = free drawing with stimulation, draw: −0.593 arb. units ± 0.116, n = 153, rest: −0.553 arb. units ± 0.122, n = 156; green = template-guided drawing without stimulation, draw: −0.588 arb. units ±0.078, n = 157, rest: −0.525 arb. units ±0.174, n = 172; orange = template-guided drawing with stimulation, draw: −0.589 arb. units ±0.096, n = 167, rest: −0.544 arb. units ±0.163, n = 173). Two-sided linear mixed-effects model revealed a significant effect of movement interval (P < 0.001) as well as an interaction between stimulation and movement interval (P = 0.039). The top lines indicate the results from the significant post hoc tests (two-sided, bonferroni corrected), combined across the drawing conditions (free and template): a rest_off > draw_off, P < 0.001; b rest_off > draw_on, P < 0.001; c rest_on > draw_off, P < 0.001; d rest_on > draw_on, P = 0.001. *P < 0.05 (Bonferroni corrected).
