Dropsites for ventral tegmental area (VTA) and nucleus accumbens septi (NAcc) Injector Cannula. Placement of injector cannula into the NAcc and VTA. Dots represent the deepest portion of the injector cannula tip. Some dots represent more than one dropsite. (A) NAcc injector cannula placement in rats tested for reinstatement; n = 31. Plates = +2.20, +1.70 mm. (B) VTA injector cannula placement in rats tested for reinstatement; n = 32. Plates = −3.40 and −3.60 mm. Example photographs of injector placement are shown in the (C) NAcc and (D) VTA. Tip = bottom of injector tip, SN = substantia nigra, AC = anterior commissure.
