It is situated ventral to the lateral spinothalamic fasciculus, but its fibers are more or less intermingled with it.
It is also known as the spino-quadrigeminal system of Mott.
In the brain-stem the fibers run lateral from the inferior olive, ventro-lateral from the superior olive, then ventro-medial from the spinal tract of the trigeminal; the fibers come to lie in the medial portion of the lateral lemniscus.
