TABLE 2. Number of Terminals Containing Multiple Synapses.

| 2 synapses: | 5 | 7 | 2 | 1 | ||
| 3 synapses: | 3 | |||||
| 4 synapses: | 1 | |||||

| Total: | 15 | 12 | 9 | 2 | 1 | |
| Avg. synapses/ terminal: |
2.73 | 1.58 | 1.22 | 1.5 | 1 | |
| SE: | 0.39 | 0.16 | 0.16 |
Data are from terminals in which 10 or more serial sections were examined. The average synapses/terminal was significantly different in a comparison of Lg Rnd, Sm Rnd, and Pleo types (Kruskal-Wallis, P=0.004). Although most terminals extended beyond our sections, two terminals containing Lg Rnd vesicles were completely sectioned and one formed five synapses and the other formed one synapse. One terminal containing Sm Rnd vesicles was completely sectioned and it formed two synapses. Three terminals containing Pleo vesicles were completely sectioned and each formed one synapse.
