Extended Data Fig. 13: Spatial distribution of newly formed and eliminated boutons.
From: Remodelling of corticostriatal axonal boutons during motor learning
a, Spatial distribution of newly-formed and eliminated boutons along M1 axons throughout training. Black vertical lines indicate boutons that persisted throughout the imaging sessions, red circles indicate newly formed boutons, and blue circles indicate eliminated boutons. b, Cumulative distribution of nearest neighbor distance for newly formed boutons in the control (black) and training (red) group (P = 2.47 × 10−6, two-sided Kolmogorov–Smirnov test). c, Average nearest neighbor distance of newly formed boutons in control (black) and training group (red) mice (P = 0.01, two-sided Wilcoxon rank sum test, control: n = 9 mice; training: n = 8 mice). d, Average nearest neighbor distance of eliminated boutons in control (black) and trained (red) mice (P = 0.17, two-sided Wilcoxon rank sum test, control: n = 9 mice; training: n = 8 mice). e, Cumulative distribution of nearest neighbor distance for newly formed boutons in shuffled (black) and training (red) group. f, Average nearest neighbor distance of newly formed boutons in shuffled (black) and training group (red) mice (P = 0.0014, two-sided paired t-Test, n = 8 mice). *p < 0.05, **p < 0.01, NS, not significant. Error bars represent SEM.
