Plots of calcium transient amplitude (L) and half-duration (M) evoked by spine or shaft input stimulation corresponding to low- and high-amplitude somatic eEPSCs (low vs. high: 7 vs. 7 spines, 11 vs. 12 shafts, 15 cells, 14 mice; amplitude:*p = 0.01; half duration:*p < 0.03, Wilcoxon signed-rank test).
