Increased coherence between OB and EC during correct trials. a, d Representative samples of filtered LFP signals in OB and EC at low (0–12 Hz) and high frequencies (30–80 Hz), respectively, during correct (blue) and wrong (red) trials. b, e OB–EC coherence across the delta (< 4 Hz), theta (4–12 Hz), gamma-1 (30–50 Hz), and gamma-2 (50–80 Hz) frequency bands. c, f Coherence between OB and EC was significantly higher within correct than wrong trials (data averaged for either correct and wrong trials of each animal completed the task 2 s pre and 1 s post the RP). Plots show the comparisons between the coherence mean of correct (blue dots) and wrong (red dots) trials of each animal (connected with lines). Data were analyzed by paired t test, n = 6. * p < 0.05, ** p < 0.01 and *** p < 0.001. RP, reference point; LFP, local field potential; OB, olfactory bulb; EC, entorhinal cortex
