The recorded P_RC and P_nRCI and predicted, P_RC(d) = P_E(d)P_I(d) and P_nRCI(d) = P_I(d)(1 − P_E(d)), did not differ at any distance (values of p > 0.05, two-tailed, Fisher's exact test). Recorded and predicted values also did not differ when connections <50 μm were pooled (values of p > 0.05, two-tailed, Fisher's exact test).
