Untangling Brain-Wide Dynamics in Consciousness by Cross-Embedding
Fig 4
Dynamical complexity and directed interaction within awake and anesthetized brain.
Unlike anesthetized brain, awake brain exhibited clear differentiation between frontoparietal and occipital areas. This figure provides results in a single representative experiment, where subject state was changed from awake (A and B), eyes-closed condition to anesthesia by injection of propofol (C and D). Loci of bubbles correspond to electrode positions; the colors of bubbles indicate (A and C) the complexity or (B and D) the directionality averaged across forecast electrodes. (The absolute values of complexity/directionality are also indicated by sizes of bubbles, for visibility.) (E) Area-wise complexity and directionality. Thin lines correspond to the individual electrodes, and thick lines indicate averages and standard errors across electrodes within each area.
