Probability distributions of EEG inter-occurrence times (500 equal logarithmic bins) and fittings with statistical models. Superimposed signal recorded on the \(P_z\) location of ten subjects performing a work memory task. Amplitude threshold = 1.0 standard deviation. Fitting within Boltzmann-Gibbs statistical mechanics for non-complex systems (i.e., \(q=1\), dashed red curve). Fitting within nonextensive statistical mechanics for complex systems (i.e., \(q\ne 1\), black continuous curve). See Methodology for details.
