Neural Circuit Mechanisms of Disorders of Consciousness and Potential Therapeutic Targets of Brain Stimulation

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
This review integrates three hierarchical frameworks—ascending reticular activating system (ARAS), mesocircuit hypothesis, and intrinsic connectivity networks (ICNs)—to update the neural mechanisms of disorders of consciousness (DoC). We highlight emerging evidence for glutamatergic ARAS pathways, a bidirectional GPi–GPe mesocircuit regulating ...
