This axonal process is a member of those that make up the spinothalamic tract, one of the major routes of nociceptive signaling[GO][GO:0021963]. NLXANAT:1010017 A tract that originates from neurons in the spinal central gray and projects to various somatosensory nuclei of the thalamus. It is formed in the medulla by merger of the anterior spinothalamic tract and lateral spinothalamic tract (adapted from Braininfo.org).
