Global Neuronal Workspace Theory posits that consciousness occurs when localized sensory signals cross an attentional threshold and “ignite” a central, long-distance frontoparietal network. Once inside this workspace, the information is globally broadcast back to otherwise isolated brain modules. This widespread broadcasting synchronizes the neural network, making the data simultaneously available to multiple systems—such as working memory, emotional evaluation, motor planning, and verbal report—creating a unified conscious experience.
