Anterior spinothalamic tract

The ventral spinothalamic fasciculus (or anterior spinothalamic tract) situated in the marginal part of the anterior funiculus and intermingled more or less with the vestibulo-spinal fasciculus, is derived from cells in the posterior column or intermediate gray matter of the opposite side. This tract is primarily associated with the conduction of soft nociceptive information to the reticular formation in the thalamus.
