Suppression of the jaw-opening reflex by conditioning A-delta fiber stimulation and electroacupuncture in the rat

Selective conditioning stimulation of A-delta fibers in the peripheral nerve with triangular pulses as well as electroacupuncture to the hind leg (5 Hz, 15 min) strongly suppressed the jaw-opening reflex in a lightly anesthetized rat, whereas maximal A-beta fiber stimulation with rectangular pulses...

Summary:Selective conditioning stimulation of A-delta fibers in the peripheral nerve with triangular pulses as well as electroacupuncture to the hind leg (5 Hz, 15 min) strongly suppressed the jaw-opening reflex in a lightly anesthetized rat, whereas maximal A-beta fiber stimulation with rectangular pulses was almost ineffective. Hence, the participation of A-delta fibers in electroacupuncture analgesia is suggested.
