(A) Schematic drawing of Bregma −9.50 mm Paxinos and Watson Atlas. The gray area represents the summarized location in Pr5 of the FlGo injections in all cases. (B) Microphotograph of a coronal section in animal RE11 showing the injection side in Pr5 (limited by dashed line). (C) Schematic drawing of Bregma −15.7 mm showing the limits of the FB injection in Sp5C represented by gray area. (D) Microphotograph of a coronal section showing the injection site in Sp5C (limited by dashed line) in animal RE8. Calibration toolbar: B: 400 µm, D: 300 µm.
