Reil's Ribbon

The Reil's ribbon, alson known as medial lemniscus, is a bundle of myelinated nerve fibers located in the medulla oblongata. Arising from the cuneate and gracile nuclei, they run up and decussate (cross) before going up into the pons where they fan out laterally. The Reil's ribbon fibers end up in the thalamus's ventral posterior nucleus. Function: the transmit sensitive impulses involving tactile discrimination.
