BACKGROUND: Disorders of consciousness (DoC) present significant therapeutic challenges with limited effective interventions. The choice of anesthetic agent during procedures such as spinal cord stimulation may influence long-term neurological outcomes, yet comparative evidence is scarce. This prospective, non-randomized, comparative effectiveness trial investigated the neurophysiological and...
Global signal regression (GSR) is widely used in functional magnetic resonance imaging (fMRI) analysis, yet its effects on anesthetic-related brain activity are not well understood. Using fMRI data from patients under general anesthesia, we analyzed temporal variability indices, amplitude of low-frequency fluctuations, functional connectivity, and graph theoretical measures with and without...
