The arcuate fasciculus is a fibrous tract in the white matter of the brain that connects the frontal lobes with areas in the Angular Gyrus, and Temporal Lobe. It is assumed to be involved in speech. It may also allow communication between the Meta-Cognitive areas in the prefrontal cortex, and the consciousness center in the Angular Gyrus. If so it might support the Angular Gyrus Model of Consciousness (AGMC).
