Where Is the Spinotectal Tract?

aka spinotectal tract, the spinomesencephalic tract is part of the anterolateral system; it terminates in the periaqeductal gray of the midbrain. The periaqueductal grey is thought to be an area that is important to inhibiting or controlling pain sensations and so the spinomesencephalic tract contributes to that role.
