Coherence distribution during working memory performance. A Schematic display of OB coordination on the vHPC–mPFC circuit. B Schematic illustration showing examples of correct and wrong working memory performance. The correct trials are defined when the animal enters the other two arms without redoing its steps (i.e., Arm A–B–C and ABA is considered a wrong trial). C Representative of coherence value when the animal is spontaneously alternating in the Y-maze. LFPs are binned into the positional frame, and the mean pixel coherence is color-coded to generate the coherence on the Y-maze map. Graphs show that the corresponding coherence between OB and mPFC increases when the rat explores the maze center to enter the correct arm (left panel).
