Fig. 5: SBI of SGM parameters over the developmental period.
From: Simulation-based inference of developmental EEG maturation with the spectral graph model
The evolution of inferred spectral graph model (SGM) parameters is visualized over time. Each colored circle represents the peak value of the respective SGM parameter distribution (y-axis) for a respective subject, as inferred by simulation-based inference (SBI), plotted over respective age of the subject (x-axis). The linear regression model fit is represented by the solid line and the shaded area represents 95% confidence interval. α demonstrated Pearson r = 0.284 (p = 3.88e−5). Axonal conduction speed demonstrated r = 0.350 (p = 2.97e−7). Excitatory Gain demonstrated r = −0.430 (p = 1.40e−10). Inhibitory Gain demonstrated r = 0.388 (p = 1.01e−5). Graph time constant did not demonstrate a linear correlation with age (Supplementary Fig. 17). The x-axis tick labels are log-scaled for visualization purposes. Symbols and abbreviations: Excitatory time constant, τe (blue); Inhibitory time constant, τi (orange); Long-range coupling constant, α (green); Axonal conduction speed, S (red); Excitatory gain, GEI (purple); Inhibitory gain, GII (brown).
