Fig. 3: Experimental PNS threshold curves for the Connectome 2.0 head-only gradient coil (red) and the original Connectome coil (grey).

The raised threshold curves of the Connectome 2.0 coil, together with the increased hardware performance space determined by Gmax and SRmax (red-shaded area), increase the performance space that can be safely used in humans compared with the Connectome 1.0 gradient coil. The number of human participants in this volunteer study was n = 29. Note that the thresholds shown here are population mean PNS thresholds, not those from the SAFE model. We use Gstim to reflect the smallest stimulation gradient amplitude (zero-to-peak convention).
