Quantitative Estimation of the Nonstationary Behavior of Neural Spontaneous Activity
Figure 2
Hypothetical illustration of a second-derivative generic plot, associated with a function . Vertical axis depicts the amplitude of , as defined in (6); whereas, horizontal axis presents the values of . Signal rupture points take place exactly at times , for which function attains a peak of amplitude 1. The stationarity intervals are used to estimate the final ST of a single MEA channel, based on (7).
