In a pioneering study, a team of researchers from Massachusetts General Hospital and Boston Children’s Hospital have identified a brain network essential for human consciousness. Aided by advances in ultrahigh-resolution magnetic resonance imaging (MRI) technology, researchers discovered previously unknown pathways connecting various brain regions, forming what they termed the “default ascending arousal network” (DAAN). In findings published in Science Translational Medicine, researchers propose that this brain network plays a pivotal role in maintaining wakefulness and integrating arousal with awareness in the resting human brain. The discovery could be a significant breakthrough in understanding a range of neurological disorders while shedding...
