Overview

The spinotectal tract (spinotectal fasciculus) is supposed to arise in the dorsal column and terminate in the inferior and superior colliculi.

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.
