<P> The axons of the tract cells cross over ( decussate ) to the other side of the spinal cord via the anterior white commissure , and to the anterolateral corner of the spinal cord ( hence the spinothalamic tract being part of the anterolateral system ) . Decussation usually occurs 1 - 2 spinal nerve segments above the point of entry . The axons travel up the length of the spinal cord into the brainstem , specifically the rostral ventromedial medulla . </P>
where does decussation occur in the spinothalamic pathway
1 - 2 spinal nerve segments above the point of entry
