Effect of electro-acupuncture of "Neiguan" on spontaneous discharges of single unit in amygdaloid nucleus in rabbits.
In this paper, the regularity on spontaneous discharges of the single unit in amygdaloid nucleus (AMYG) in rabbits were analyzed and whether the signal of Electro-acupuncture (EA) at Neiguan (P 6) can reach the AMYG was further observed with the technique of glass microelectrode. It was found that the signals of EA at Neiguan can reach AMYG and activate or inhibit the electrical activity of some neurons, manifesting two response patterns: frequency-increasing and frequency-decreasing. Additionally, the same neuron had a different response to the signals of EA at Neiguan and Zusanli (St 36), suggesting that a relative specificity of acupoints is present.
