Transient Off-cells were defined by transient (<500 ms) inward currents in response to the offset of optimally sized light stimuli. Cells were identified according to previously published morphological criteria (Amthor et al. 1989; Rockhill et al. 2002). Each of the 3 transient Off-cells included in this study had different morphologies and displayed different responses to mAChR blockade. The average changes in peak currents of transient Off-cells with light responses that were significantly affected by pharmacological blockade are shown for each cell.
