context_page_description: The spinotectal tract arises in the spinothalamic tract and terminates in the inferior and superior colliculi.
  It is situated ventral to the lateral spinothalamic tract, but its fibers are more or less intermingled with it.
  In the brainstem 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.
