Trochlear nerve

The trochlear nerve was a motor nerve that innervated one of the muscles of the eye.
In 2374, a Borg implant was pressing against Seven of Nine's trochlear nerve, causing her to go into neural shock when treated by The Doctor. Kes was able to eliminate the implant with her burgeoning psychokinetic powers without damaging the nerve. ()
