According to this theory, the brain operates with a "global workspace" that serves as a kind of central information processing and broadcasting system. It suggests that information processing in the brain occurs in a distributed and specialized manner, but only a small fraction of this information becomes conscious and enters the global workspace. Once information reaches the global workspace, it can be accessed and shared across different parts of the brain, making it available for conscious awareness.
The Global Neuronal Workspace theory posits that conscious experiences are a result of the competition among various neural processes to gain access to this global workspace. When specific information or representations are broadcast to this global workspace, they become part of our conscious experience. This theory has been influential in the field of cognitive neuroscience and has contributed to our understanding of the neural basis of consciousness and how different brain regions contribute to our subjective experience.
