CAP metrics as a function of stimulus intensity. With increasing intensity, peak-to-baseline amplitude increased (became more negative) (A), peak and onset latencies decreased (B and C), and half-width increased (E), as expected. Although not significant, area increased with increasing intensity (D). PLVs increased with increasing intensity (F), indicating increased synchrony of N1. Individual data points were randomly jittered around each intensity for clarity in display. Each dot represents data from a single participant, and solid line represents the regression of the variables by intensity.
