Estimation of event timing in control brain regions outside the learning-related regions of interest. To compare feedback responses across conditions in ROI analyses, time courses were extracted from independent, anatomically defined “control” regions and the critical time points associated with the Immediate versus Delay feedback conditions were estimated. Time courses extracted from regions demonstrating stimulus and feedback task events are plotted. A, Time points illustrating the STIMULUS plus RESPONSE event of the task were extracted from the left post-central gyrus. B, Time points illustrating immediate and delayed FEEDBACK events were extracted from the right parahippocampal gyrus, widely known to respond to images of scenes (Epstein and Kanwisher, 1998). The percentage signal change across time bins at 6 and 8 s were averaged for the Immediate feedback condition and time bins at 12 and 14 s for the Delayed feedback condition. Error bars represent ±1 SEM.
