Fiber pathways that lie within the cerebrum that connect one part of the cerebral cortex with another within the same hemisphere. Association pathways are thus contrasted with commissures that generally interconnect homologous areas of the two halves of the brain, and projection pathways that are fiber tracts interconnecting cortical and subcortical structures. They may be very long (typically termed fasciculi) or very short. The latter may consist of “U”-shaped fibers connecting one gyrus with an adjacent one or horizontal connections within a gyrus itself (e.g., bands of Baillarger). These various pathways allow different areas of the brain to communicate with one another. Some of the major association pathways are shown in Fig. 1.
