Figure 3From: Place preference induced by nucleus accumbens amphetamine is impaired by local blockade of Group II metabotropic glutamate receptors in ratsMean (+SEM) activity counts (per 30 min) during conditioning sessions. Activity counts on the drug- (left panel) and vehicle-paired (right panel) sides are shown. Groups were treated with 0.0 – 0.8 μg EGLU followed by amphetamine (20 μg) immediately before placement on the corresponding side of the conditioning apparatus. One group received 0.1 μg EGLU alone, i.e. no amphetamine was administered before conditioning sessions. See Table 1 for number of animals per group.Back to article page
