(a) Down-phase-stimulated animals attempt significantly less than control animals during the last bin (two-way repeated measures analysis of variance [RM-ANOVA], condition * bin interaction, F(2, 18) = 4.03, *p=0.036; down * mock, *p=0.037). (b) In relation to the proportion of attempts per bin to the total number of attempts, down-phase-stimulated animals again show a sharp decrease towards the end of the session (RM-ANOVA, condition * bin interaction, F(2, 18) = 5.24, *p=0.016; first-bin * last-bin, **p=0.004). (c) Attempting speed shows a non-significant decline from the first to the fifth bin in the down-phase-stimulated subjects (RM-ANOVA, condition * bin interaction, F(2, 18) = 1.33, p=0.291). (d) Up-phase-stimulated animals show a consistent increase in successful attempts from the first to the fifth bin, in all motor-training (M-T) days. Conversely, down-phase-stimulated animals were always slightly less successful towards the end of each session, although this might be due to the drop in attempts within the last testing window (plotted as the log2 of the fold-change of the number of successes of the last bin to the first bin of a session: –1 represents a 50% drop in successes, while 1 represents twice more successes from first bin).
