Fig. 7

Data are plotted as percent change (± SEM) from the baseline number of infusions obtained by the short- and extended-access groups following systemic treatment as a function of dose (mg/kg)/treatment (0/Vehicle, 0.05 and 0.1 eticlopride, 0.5 and 1.0 SCH-23390, and 1.5 mg/kg CNQX; short-access, n=10, 9 and 11, 10 and 9, and 12, respectively; extended-access, n=8, 9 and 12, 12 and 11, and 11, respectively). A (#) indicates a significant difference between the extended- versus short-access groups following treatment with the high dose of eticlopride (1 mg/kg) and CNQX. An (*) indicates a significant difference from baseline/0 (no change).
