Energy: a useful criterion in analysis of human visual evoked response.
Visual evoked responses from a diffuse Xenon flash were studied for seven normal and 14 abnormal subjects. Amplitude and latency measurements of the waveforms were compared with an energy function calculated from the area beneath a curve of the VER voltage squared and summed over the interval from 0 to 125 msec. This energy function proved superior to latency in detecting asymmetrical responses and similar to latency in detecting symmetrically reduced waveforms.
