Pain and temperature are carried by:

VENTROLATERAL SPINOTHALAMIC TRACT Fibers from nociceptors and thermoreceptors synapse on neurons in the dorsal horn of the spinal cord. The axons from these dorsal horn neurons cross the midline and ascend in the ventrolateral quadrant of the spinal cord, where they form the ventrolateral spinothalamic pathway. Fibers within this tract synapse in the VPL.
