F0: fluorescence intensity of synapses before stimulation
ΔF: the peak change in fluorescence intensity upon stimulation
ΔF/F0: the signal-background ratio
ΔF/F01/2: the signal-noise ratio
Data are obtained from a stimulation with 40 action potentials at 20Hz, normalized to the corresponding value of Synaptophluorin, presented as mean ± SEM
