Chronic ropinirole (Rop) and D‐512 increased spontaneous movement in motion chambers (n = 10 per group). Rats were treated for 22 days with ropinirole, D‐512 or vehicle (all doses were increased on day 8). Movement data were analysed for total distance travelled (in mm) and the number of discrete movements (defined as the number of start–stop motions separated by at least 1 s) on (A, B) day 3 (C, D) day 10 and (E, F) day 17. Tukey's HSD was used for between‐group comparisons at each time point: bars that share the same letter are considered statistically comparable, while bars with different letters are considered statistically different.
