|Latin||tractus spinothalamicus anterior|
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.
This is a somewhat doubtful fasciculus and its fibers are supposed to end in the thalamus and to conduct certain of the touch impulses. More specifically, its fibers convey crude touch information to the VPL (ventral posterolateral nucleus) part of the thalamus. Iqbal's physiology notes this tract acts via slow neuronal communications.
