Table 1. Comparison of LM-based and EM measurements.

Bouton IDs match those in Figures 3 and 4. The probability that a putative bouton belongs to the category of LM boutons, $P (b o u t o n | w)$ was calculated according to Equation (9) with $w_{t h r e s h o l d}$ = 2.0. Bouton #8 (grey) was excluded from the analyses as it is a terminal bouton. Hyphens indicate that boutons, mitochondria, or PSDs were not detected in EM.
