Figure 3. Acute whisker stimulation leads to an increase in spine sGluA1 and shaft sGluA1, but has little effect on spine size.

Figure 3

a, Spine structure intensity (dsRed2 signal) at hour 0, 1, 2, and 3 in control and stimulated animals. b, Spine sGluA1 intensity (SEP-GluA1 signal) in control and stimulated animals. c, Shaft sGluA1 intensity in control and stimulated animals. d, Categorization of spine sGluA1 responses at hour 1, same (> 70% and < 130%), up (≥ 130%), and down (≤ 70%). e, Changes in spine structure intensity (left) and in spine sGluA1 intensity (right) at hour 1 in distant unstimulated barrels. f, Average sGluA1 intensity in spines belonging to the same dendrites in control and stimulated animals. g, Categorization of dendritic responses at hour 1 into the same, up, and down categories (same criterion as panel d). 585 spines, 52 dendrites in 6 stimulated animals; 493 spines, 38 dendrites in 5 control animals. 40 spines, 6 dendrites in 2 animals (distant unstimulated barrel in e). ***p < 0.001, **p < 0.01, two-way analysis of variance (ANOVA) with Bonferroni posttests. Error bars = s.e.m.
