For head discriminative touch, they are located in the pontine trigeminal nucleus and the pars oralis of the  spinal  trigeminal  nucleus.  The  second-order neurons project to the contralateral VPm through the ventral trigeminothalamic tract. In addition, smaller numbers of axons, crossed and uncrossed, proceed  from  the  pontine  trigeminal  nucleus  to the VPm in the dorsal trigeminothalamic tract. The dorsal funiculus of the spinal cord transmits impulses  for  ipsilateral  discriminative  touch  and proprioception.  The  gracile  fasciculus  is  concerned  with  s...
