Differential EEG effects of increased sensorimotor demands (object slant) as a function of TMS site. Left, aIPS versus control. Right, sPOS versus control. A, Differential topographies of alpha power representing significant modulation of the effect of slant (grasping horizontal > vertical objects) as a function of stimulation site. The enhanced alpha-suppression after control stimulation for horizontal objects is disrupted both by aIPS and sPOS stimulation, but in a different time-window (aIPS: [−40 380] ms; sPOS: [300 580] ms relative to movement onset). B, C, The differential effects of slant are plotted separately following control (left and right panels; gray), aIPS (left panels; magenta), and sPOS stimulation (right panels; cyan) for electrode Fz (B) and the average of electrodes POz and Pz (C). Significant time windows are indicated with gray boxes.
