Covariation of excitatory inputs to cells that share little known circuitry. a. Simultaneous recordings of excitatory synaptic inputs to an ON and an OFF parasol ganglion cell during modulated and constant light (top trace; 50% contrast, mean 4000 R*/cone/sec). Holding potentials were ~−70 mV. b. Crosscorrelation functions for the excitatory synaptic inputs measured during constant light (excluding 500 ms following the end of modulate light period; see Methods) from the same cell pair as a (left) and averaged across 9 cell pairs (right; mean ± SEM). c, d. Correlations in excitatory synaptic inputs to ON midget and ON parasol ganglion cells as in a and b (n = 18). e, f. Correlations in excitatory synaptic inputs to horizontal cells and ON parasol ganglion cells as in a and b (n = 5). Recordings for a–d were in flat mount preparations, and those in e and f were in slice preparations.
