Fig 2. Models of human cortical microcircuits reproduce key features of resting-state EEG.

(a) Power spectral density plot of circuit simulations (n = 60 randomized microcircuits, bootstrapped mean and 95% confidence intervals), exhibiting peak power in theta and alpha frequency bands. Inset–same power spectral density plot shown on log-log scale, illustrating the 1/f relationship between power and log frequency, inversely linear between 3–30 Hz with slope -1.17 ± 0.09. Frequency bands are delimited by dotted lines. (b) Example spectrogram of simulated microcircuit EEG, exhibiting theta and alpha events.
