Action potential threshold of wide dynamic range neurons in rat spinal dorsal horn evoked by manual acupuncture at ST36
ST36 of six rats is acupunctured with three different frequencies. Evoked spikes in wide dynamic range neurons in spinal dorsal horn are recorded. The threshold voltage of the action potentials is dynamic. The broad variations in spike threshold are robust to acupuncture frequency. The spike threshold is inversely related to the rate of rise of membrane potential.
