The band of nerve fibers which cross the midline of the spinal cord ventral to the central canal and posterior grey commissure[MP]. 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. A N4 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[WP].
