global neuronal workspace theory of consciousness

E910003

The global neuronal workspace theory of consciousness is a cognitive neuroscience model proposing that conscious experience arises when information is globally broadcast across widely distributed, interconnected brain networks, particularly involving fronto-parietal circuits.
