Long-term monitoring of neural potential and high-gamma power responses to median nerve stimulation. (a,b) represent Monkey C, and (c,d) show analogous data for Monkey B. In each panel, the top-left subpanel displays a trial-averaged SEP waveform (z scored) aligned to stimulus onset (red vertical line), with the red horizontal line showing the baseline period. The ~23 ms peak, indicated by a black arrow, is a hallmark of early cortical activation following median nerve stimulation. The bottom-left subpanel presents a topographic map of the SEP amplitude (of z scores) at that peak latency. The orientation is as shown in Fig. 1c; black- and red-outlined electrodes denote task-relevant and exemplar channels, respectively. On the right, a heatmap depicts the temporal evolution of the SEP peak response (z score) across multiple recording days (horizontal axis) for all channels (vertical axis). Warmer colours denote higher z scores, indicating stronger SEP amplitudes.
