The anterior (or ventral) white commissure, also known as the "alba anterior medullae spinalis", is a bundle of nerve fibers which cross the midline of the spinal cord just anterior to the gray commissure (Rexed lamina X). A δ fibers and C fibers carrying pain sensation in the spinothalamic tract contribute to this commissure, as do fibers of the anterior corticospinal tract, which carry motor signals from the primary motor cortex.
