The ventral spinothalamic fasciculus (or anterior spinothalamic tract) situated in the marginal part of the 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.

Their axons cross in the anterior commissure.

This is a somewhat doubtful fasciculus and its fibers are supposed to end in the thalamus and to conduct certain of the touch impulses.
