Experimental paradigm. (A) ROIs and recording probe orientation. Circles on the cortical surface reconstruction indicate the positions of the epidural surgical implants. The call-out circles show a magnified view of each ROI. To ensure accurate resampling over successive sessions, two perpendicular axes (fine lines) are defined across each ROI, with which the recording probes are aligned. Recording channels designated as F1–F7 and P2–P8 refer to sampling positions in pFC and PPC, respectively. Yellow circle, light emitter; orange circle, detector; black dot, electrode. (B) Behavioral tasks. The task panel contains a horizontal array of three touch responsive display buttons that register the animal’s manual selections by photocells. Each row in the diagram depicts the possible stimulus presentation sequences in each of the respective tasks. c = correct choice.
