For our PROBLEM SOLVING, you must know that a lesion of spinal tract V along its entire course (the pain information never gets to the caudal spinal nucleus) results in IPSILATERAL deficits in pain and temperature from the face etc. Interruption of the trigeminothalamic tract, which is comprised of axons that have crossed the midline, results in deficits in pain and temperature on the contralateral side of the face etc. |
