Fig. 5. Modulation of inhibitory gain by empirical GABA-A receptor density improves model fit to DOC brain dynamics.

Fig. 5

Box-plots show the KS-distance (lower is better) to the empirical brain activity of DOC patients, for n = 100 simulations of a model that (a) is informed by empirical GABA-A regional density, using the value of gain for inhibitory scaling sI derived from calibrating the model with respect to healthy controls’ empirical brain activity (blue); (b) is informed by empirical GABA-A regional density, using the value of gain for inhibitory scaling sI that provides the best fit to the DOC patients’ empirical brain activity (red); (c) same as (b), but the regional receptor densities are randomly reshuffled across the cortex; (d) same as (b), but the receptor densities are all set to a uniform value (the mean of the empirical distribution). Middle line: median; box limits, upper and lower quartiles; whiskers, 1.5x inter-quartile range; “+” symbol indicates outliers; ***p < 0.001. n.s. Not significant (p > 0.05) from t-test.
