Analysis of the <i>P_II</i> response.

<p>Overlaid representative scotopic waveforms of a normal subject (grey lines) and patient BCM5 (chain lines) and the extracted P_II components (B) are presented. The delay in implicit times to reach a threshold amplitude of 50 µV at each intensity level is plotted in a log-log diagram both for the NOP group and ALP group (C).
