Fig. 3From: Effect of Electroacupuncture on the NTS is modulated primarily by acupuncture point selection and stimulation frequency in normal ratsThe distribution of three types of neurons and the rate of change for spike frequency in NTS neurons after same EA frequency stimulated at ST 36 or ST 25. The population of three type neuron in NTS at 10 min after 2 Hz (a), 100 Hz (c) or 2/100 Hz (e) EA administrated. The change rates of spike frequency of NTS neurons at 9 min after 2 Hz (b), 100 Hz (d) or 2/100 Hz (f) EA administrated. Results of the counts of three types of neurons are real numbers and the rates of change of spike frequency are mean, quartile and standard deviation. n = 5. *P < 0.05, **P < 0.01 versus control group, △P < 0.05, △△P < 0.01 versus ST 36 groupBack to article page
