Disorders of consciousness illustrate the complexity of brain mechanisms underlying awareness from "summary" of The Cognitive Neuroscience of Consciousness by Stanislas Dehaene
Disorders of consciousness, such as coma, vegetative state, and minimally conscious state, present profound challenges to understanding the neural correlates of awareness. These conditions highlight the intricate interplay between various brain regions and networks that contribute to conscious experience. Different levels of consciousness can emerge from distinct neural configurations, underscoring the brain's remarkable adaptability and complexity. For instance, the distinction between a vegetative state and a minimally conscious state reveals how subtle variations in brain function can lead to significant differences in awareness. In a vegetative state, patients may exhibit sleep-wake cycles and reflexive responses but lack purposeful behavior or conscious awareness. In contrast, those in a minimally conscious state display intermittent signs of awareness, suggesting that certain neural pathways remain intact and capable of supporting conscious processing. Neuroimaging studies have shown that specific brain networks, such as the default mode network and the frontoparietal network, are crucial f...
