Diagrammatic representation of the experimental procedure. First, participants were comfortably seated in an experimental chair, and neuronavigation setup as well as EMG electrode placements were done. This was followed by motor hotspot determination—via the manual (MHS) or the cobot (CHS) methods using the B60 and the AP65 coils, respectively. Finally, measurements of RMT, SI1mV were made, and MEP measurements with 120% RMT (20 MEPs), and SI1mV (25 MEPs) were recorded at CHS, and MHS locations. All recordings of MEPs at both hotspot locations were made with the AP 65 coil to avoid any differences in measurement due to coil characteristics. MHS, manual hotspot search; CHS, cobot hotspot search.
