a Validation of turbulence measure in a ring of Stuart-Landau (SL) oscillators with non-local coupling (first panel), where, crucially, there is a known analytical solution to where the turbulent regime is found. b The panel shows how we constructed the spatially coarse observations by averaging over 100 neighbouring oscillators. c The panel shows an example of the phases of these coarse measurements for simulations in the turbulent regime. d The panel shows the bifurcation diagram for the analytical analysis and the performance of the different measures of turbulence. e The pipeline of pre-processing MEG data shows the sensor signals. f These signales are beamformed and a coarse DK68 parcellation was used to extract the MEG signals. g The panel shows examples from each coarse parcel in the five classical bands (delta 1-3 Hz, theta 3.5-7 Hz, alpha 7.5-13.5 Hz, beta 14–30.5 Hz, gamma 31–40 Hz). h The panel shows examples of the measures of empirical turbulence on representative successive timepoints are rendered on sideways, midline and flat map renderings of the whole brain.
