Table 1.

Number of vesicles at motor nerve terminals

	Crayfish	Mouse
Control
Vesicles/μm2	123.00 (±25.00)	35.54 (±5.36)
Avg. cluster area, μm2	0.20
Avg. terminal area, μm2		4.25
T-588
Vesicles/μm2	70.51 (±15.00)	24.28 (±5.15)
Avg. cluster area, μm2	0.21
Avg. terminal area, μm2		4.40

For crayfish, n = 89 for control and n = 52 for T-588. For mouse, n = 28 for both control and T-588.
