Abstract
Brief, dim flashes of light that produced on average only one response per three to six flashes were presented to dark-adapted locust photoreceptors. The amplitude, latency, and half-duration of the discrete voltage responses showed substantial variation. However all frequency distribution curves were single peaked, indicating that there is only one class of discrete voltage responses in the locust. Correlations between these parameters are low (accounting for less than 7% of the variance) but statistically significant. The low correlations suggest that different processes underlie the generation of amplitude, latency and duration of the bumps.
