N1 peak latency. Left panel. Anatomical distribution of the peak latency of the N1 potential. The colour scale indicates the CCEP peak latency. Black dots indicate the contacts whose HF-ES induced laughter and whose SPES was used for the CCEP study. Both left and right contacts are plotted on the right hemisphere of the inflated surface of the FS_LR brain template. Right panel. Representative CCEP for each of four temporal windows (CCEPs with latency greater than 40 ms not shown). (Online version in colour.)
