Exposure to stress during increased expression of 5-HT1B receptors in the NAc is necessary for increasing susceptibility to the acute locomotor effects of amphetamine. Data are from the increased 5-HT1B receptor expression groups following each treatment of the multiple-dose acute locomotor response test (habituation (Hab), saline (Sal), 0.5 and 2 mg/kg amphetamine (Amph)) and are plotted as the mean (± SEM) percent of crossovers of the respective GFP control groups. Grey bars represent the 1B group that did not receive exposure to stress (1B/No stress) and black bars represent the 5-HT1B group that received the stress treatment (1B/Stress). *, differs from the 1B/No stress group (p < 0.05, two-tailed t-test). N = 7–10/group.
