A: manipulandum with force sensors. Different objects can be placed in the basket to change object weight. B: example of trial with force traces of grip (GF) and load (LF) force (top) and force rates (GFR and LFR; bottom). Transcranial magnetic stimulation (TMS) was applied as a burst of 3 pulses at 10 Hz at contact (TMSdynamic) or 500 ms after liftoff (TMSstatic). Force parameters were calculated as peak force rates (peak LFR, peak GFR) and grip force during static holding (GFstatic; average between 600 and 800 ms after liftoff, red circles). Dashed vertical line indicates liftoff; dashed horizontal line indicates object weight.
