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).
