Let me quote a line from the Kaplan USMLE-
"Central processes from cells in the trigeminal ganglion conveying pain and temperature sensations from the face enter the brain stem in the rostral pons but descend in the spinal tract of CN V and synapse on cells in the spinal nucleus."
Well I guess the answer to this would be loss of sensation of pain on same side.
Any comments??
