Time- and task-dependent effect of TMS on reaction times.
For both tasks, reaction times were improved at pre-stimulus TMS time windows and impaired at post-stimulus TMS time windows. This effect was more pronounced at pre-stimulus TMS time windows during the detection task compared to the angle task but no significant difference between tasks was observed at post-stimulus TMS time windows. Data points are slightly shifted sideways for clarity. Error bars show the standard error of the mean.
