Detection of Fractal Behavior in Temporal Series of Synaptic Quantal Release Events: A Feasibility Study

Figure 2

The three methods used for the quantification of the fractal exponent 𝛼 on simulated release series (simulations with 𝛼=1 and 𝑎_𝑓=15%). (a) Periodogram (PG), (b) Allan factor (AF), and (d) detrended fluctuation analysis (DFA). Pale-blue lines represent single realizations (𝑛=20); thick blue lines represent the average of measures; red dashed lines are fittings in the selected range. Notice how the variation between different trials is quite limited.
