Task rule selective theta activity in macaque anterior cingulate cortex just before a “decision point.” (A) Time-frequency distribution of statistical reliable task selectivity of LFP power. Time zero marks the onset of a peripheral stimulus on either right/left side and requiring either a pro-, or an anti-saccade response. (B) Task selective theta activity emerged early in those correct trials, where the task representation had to be re-established following an error response (bottom left, and red line), compared to correct trials following other correct trials (top left and blue line).
