ICV oxytocin reduces effort-based consumption of sucrose over freely available chow in a PROG/Chow choice task. (A) Schematic of the PROG/Chow choice task. (B) Ratio of sucrose intake over total intake (kCal) over the course of five days training in the choice task. (C–F) Highest PROG ratio achieved, PROG sucrose earned, free chow intake, and ratio of PROG sucrose intake over total intake in the PROG/Chow choice task following ICV oxytocin administration. (G–I) Free sucrose intake, free chow intake, and ratio of free sucrose intake over total intake in free sucrose/free chow choice task following ICV oxytocin administration. Data are mean ± SEM; *p < 0.05.
