Figure 3. Feature weight similarity predicts synaptic selectivity better than receptive field center distance.

a, Axon-dendrite co-travel distance increases with feature weight similarity and decreasing RF center distance for within-area (V1→V1, HVA→HVA), feedforward (V1→ HVA), and feedback (HVA→V1) connectivity. b,, Synapse density increases with feature weight similarity, but not with RF distance, except for HVAtoV1 projections. c, Multiple synapses are associated with increasing feature similarity, but not receptive field center distance, after regressing out $L_d$. d,, Only feature similarity (not receptive field center distance) is associated with an increase in cleft volume, after regressing out $L_d$. (For all panels, * = p-value < 0.05, ** = p-value < 0.01, *** = p-value < 0.001, p-values are corrected for multiple comparisons using BH procedure, for details, see Supplemental Tab. 11, 13, 15, 17, 12, 14, 16, 18,)
