Quantitative Estimation of the Nonstationary Behavior of Neural Spontaneous Activity

Figure 1

Example of the classical methodology for ST estimation through DFA [19]. The lower plot shows log(𝐹(𝐿))×log(𝐿); 𝛼(𝐿) is presented in the upper plot. The vertical dashed line in the middle of the figure represents the signal rupture detected by the technique in [19].
