Regression statistics are reported from amplitudes of coincident events plotted against one another. Events were considered coincident if the start of the rod event occurred within 10 ms of the peak of horizontal cell (HC) mEPSC. Six out of eight pairs show a slope that deviated significantly from zero (F-test). Rod and HC quantal amplitudes (QA) are reported, along with a coefficient of variance (CV).
