Extended Data Fig. 4: Observation of F-actin remodeling in living cells.

a, Kernel density estimate of the F-actin fibres and rings dendritic area distribution for after 30 minutes in a solution reducing neuronal activity (high Mg2+/low Ca2+, blue) or following a stimulation (0Mg2+/Glu/Ca2+, from t = 1-15min, red). b, Bootstrapped distributions of the results shown in a,. Shown are the regions comprising 95%, 99% and 99.9% of the data point distribution. Following the 0Mg2+/Glu/Ca2+ stimulation, we observe a small increase in the proportion of F-actin fibres and a decrease in the proportion of rings. High Mg2+ N=21, 0Mg2+/Glu/Ca2+ N=21.
