Extended Data Fig. 3: Spine-soma functional similarity is uncorrelated with synaptic strength.
From: Cortical response selectivity derives from strength in numbers of synapses
Relationships between the difference in direction preference (top), ocular dominance (middle), and tuning correlation (bottom) with synapse spine head volume (blue), PSD area (red), and simulated spine-soma voltage attenuation (grey). Above each plot, correlation magnitude and p-value is shown. For direction preference difference, Circular-Linear correlation coefficient was calculated. For ocular dominance and tuning correlation, Spearman’s correlation coefficient was calculated. All significance tests are one-sided.
