The spinotectal tract (spinomesencephalic tract, spinotectal fasciculus, spino-quadrigeminal system of Mott) arises in the
spinothalamic tract
The spinothalamic tract is a part of the anterolateral system or the ventrolateral system, a sensory pathway to the thalamus. From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory ...

In neuroanatomy, the superior colliculus () is a structure lying on the roof of the mammalian midbrain. In non-mammalian vertebrates, the homologous structure is known as the optic tectum, or optic lobe. The adjective form ''tectal'' is commonly ...
.
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.
