Influence of intra-accumbens 2-AG (0.25μg/0.5μl) and DAMGO (0.0025μg or 0.025μg/0.5μl) on total food hopper entry duration (* = p <.05; compared to Vehicle – 0μg DAMGO co-administration). The inset graph depicts the same data across 30 min intervals; the x-axis represents 30-min time intervals across the 2hr testing period (30, 60, 90, and 120 min) and the y-axis represents the total duration of food hopper entries.
