Ambulatory (top panels), non-ambulatory (middle panels) and vertical (bottom panels) activity measured over the two-hour test period during the training phase after the first (left panels) and the third (right panels) VM microinjections of vehicle (VEH, n = 22), 1.5 nmol of D-Tyr[11]Neurotensin (NT, n = 23), 200 pmol of Ro04-5595 + NT (Ro200 + NT, n = 5), 1200 pmol of Ro04-5595 + NT (Ro1200 + NT, n = 14), 200 pmol (Ro200, n = 5) or 120 of Ro04-5595 (Ro1200, n = 13) alone. Each bar represents the group mean ± s.e.m. Symbols indicate a statistically significant difference with respective VEH (*p < 0.05; ***p < 0.001) with respective NT group (+p < 0.05; +++p < 0.001) or between the first ant the third injections for the corresponding treatment group (##p < 0.01; ###p < 0.001). See method section for details.
