Synchrony was measured between internodal strands, varicosities, and neurochemically-identified nerve cell bodies. The A columns contain the percentage of all recorded structures such that the cross correlogram is maximized close to a time lag of 0; the B columns contain the percentage of all recorded structures such that the cross correlation function is maximized close to a time lag of 0; the C column contain the average value of the cross correlation function at time lag 0 over all sites. Block diagonal entries contain the results when both recordings in a pair belong to the same class (e.g., ChAT + ve versus ChAT + ve nerve cell bodies), the off-diagonals contain the results when the two recordings come from different classes (e.g., ChAT + ve versus NOS + ve nerve cell bodies). Note that ChAT/NOS and CGRP/NOS immunohistochemical combinations were used. Thus, there was no data (ND) for comparison of ChAT + ve and CGRP + ve nerve cell bodies.
