Figure Lengend Snippet: A, Coronal sections of the rat brain illustrating MD and mPFC electrode placements. The coordinates are based on a standard rat brain atlas . The numbers indicate distance in mm from Bregma. MDC, mediodorsal thalamic nucleus, central part; MDM, mediodorsal thalamic nucleus, medial part; Cg1, cingulate cortex, area1; PrL; prelimbic cortex. B, Outcome devaluation test. Devalued, rats received 1 h of unlimited food pellets, same as earned by lever pressing. Non-devalued, rats did not receive any food for 1 h before test. Normalized rate of presses were the ratio of presses under each condition. Error bars indicate SEM.

Figure Lengend Snippet: Representative LFP traces recorded from the four electrodes during the final session. LFPs in the MD exhibit prominent theta band (∼7–8 Hz) oscillations, whereas LFPs in the mPFC show prominent gamma band (∼50 Hz) oscillations.

Figure Lengend Snippet: A, Left, Overall coherence from two representative electrodes during the first (green) and last (red) session in MD and mPFC. Right, dynamic changes of theta and gamma coherence during 4 sessions of instrumental learning (n = 33 pairs in each session). Error bars represent SEM. B, Left, coherence upon reward delivery measured from activity from two representative electrodes. Right, dynamic modulation of theta and gamma coherence by the reward delivery. Error bars indicate SEM.
