Fig. 7: Schematic illustration of the common and specific gradient features of various states of consciousness.
From: Functional geometry of the cortex encodes dimensions of consciousness

The three cortical gradients (G1, G2, and G3) putatively represent three dimensions of consciousness, i.e., awareness, sensory organization, and arousability. Reduced network distance between ventral attention network (VAN) and default-mode network (DMN) in the 3D gradient space is associated with behavioral unresponsiveness. Dashed lines indicate the major changes during depressed states of consciousness or psychiatric diagnoses as compared to baseline conditions or healthy controls.
