Figure 6. High-frequency stimulation does not alter overlap between evoked and spontaneous transmission.

Figure 6

(A) Merged activity map showing the probability that synapses distributed throughout a wild-type NMJ participate in evoked transmission triggered either by one nerve stimulation (green), five stimulations (magenta), or both (white). Maximal observed values for this NMJ were Pr(1) = 0.7 and Pr(5) = 0.94. The correlation coefficient between these activity patterns was 0.84.

(B) Plot of Pr(5) versus Pr(1) for all synapses in the NMJ of (A). Solid line indicates no change in probability (i.e. Pr(5) = Pr(1)).

(C) Merged activity maps for the NMJ of (A), showing the probability that synapses participate in either evoked (green) or spontaneous (magenta) transmission or both (white). Right and left panels correspond to one and five nerve stimulations, respectively. For this NMJ, correlation values between the evoked and spontaneous activity maps were 0.36 and 0.24 for one and five nerve stimulations, respectively.

Scale bar in (A), 5 µm.
