ACC and OFC theta power are negatively correlated with deliberation speed during discrimination performance in eGFP rats. Theta power was filtered and extracted from ACC and OFC for each event-triggered epoch (correct choice, incorrect choice, and reward port entry). Movement speed was calculated by subtracting the time at the target event (t) from the time at the previous event (t-1) in seconds (sec). OFC theta power decreased as correct choice latencies increased after VEH administration (green) during discrimination learning. This negative correlation was not observed following CNO (purple). In reversal learning, theta power in both ACC and OFC significantly decreased as reward collection latencies increased after CNO administration (purple). This negative correlation was not observed following VEH (green). There were no significant correlations between theta power and choice of correct or incorrect stimulus in reversal learning. ^*P < 0.05.
