The lateral spinothalamic tract (or lateral spinothalamic fasciculus) which is a part of the Anterolateral system is a bundle of sensory axons ascending through the white matter of the spinal cord carrying sensory information to the brain. It carries pain and temperature sensory information (protopathic sensation) to the thalamus of the brain. It is composed primarily of fast-conducting sparsely-myelinated Aδ axons and slow-conducting unmyelinated C axons.
