Supplementary Figure 2

a, Blow-up of a field of view showing two varicosities connected by an axonal shaft. b, Fluorescence signals from varicosities shown in a. Grey bars, visual stimuli. c, RFs from the same two varicosities. d, Matrix of correlation coefficients (Pearson’s R) for fluorescent traces from varicosities recorded in the same imaging session. e, Distribution of correlation coefficients (Pearson’s R, 9 fields of view). Black, pairs of varicosities belonging to the same axon (71 varicosities, 27 axons, 67 pairs); grey, all pairs (1317 varicosities, 119827 pairs). f, Distance between RF centers. g, Correlation coefficient (Pearson’s R) vs distance between RF centers. Black dots, pairs of varicosities belonging to the same axon (n = 67 pairs); grey, all pairs (n = 119827 pairs).
