Extended Data Fig. 5: Anti-GluA1 signal increases with spine size.
From: Filopodia are a structural substrate for silent synapses in adult neocortex
a, Anti-GluA1 signal intensity as a function of head diameter for spines (red) and filopodia (yellow). b, Correlation between head diameter and anti-GluA1 signal intensity for spines. The data are fitted with a line of slope 421+/−22 using linear regression. c, Correlation between diameter of filopodium head and anti-GluaA1 signal intensity. The data are fitted with a line of slope 95+/−39 using linear regression. Correlation coefficients (r) and p-values were obtained from a two-tailed, non-parametric Spearman correlation.
