Extended Data Fig. 7. Power of 4–6 Hz during reward anticipation and receipt periods in two different tasks with different contrasts in the dlHPC hippocampal area.

(A) 4–6 Hz power time traces for sweet-fat and taste-neutral items in the sweet-fat incentive paradigm. Note, this is a repeat of Extended Data Fig. 2, left included here as a reference. (B) 4–6 Hz power time traces for monetary-gain and monetary-loss trials in the MID paradigm. (C) 4–6 Hz power time traces for the gain and loss cues contrasted with their corresponding 0-gain (magenta) and 0-loss cues (cyan), respectively. The time interval displayed for the MID task includes the pre-cue period (−1.5 to 0 s), cue presentation (0–2 s), fixation cross (2–4 s), button-press target (~0.350 s within a 4–6 s interval), and a portion of feedback delivery (6–7.5 s). Note that increased 4–6 Hz power is specific to the sweet-fat vs. taste-neutral contrast.
