The lateral spinothalamic tract (lateral spinothalamic fasciculus) is supposed to come from cells in the dorsal column and the intermediate gray matter whose axons cross in the anterior commissure to the opposite lateral funiculus where they pass upward on the medial side of the ventral spinocerebellar fasciculus; on reaching the medulla oblongata they continue in the formatio reticularis near the median fillet and probably terminate in the ventro-lateral region of the thalamus.

It is supposed to conduct impulses of pain and temperature.

The lateral and ventral spinothalamic fasciculi are sometimes termed the secondary sensory fasciculus or spinal lemniscus.
