Effect of electrical, mechanical or combined stimulation at neurogenic spots on c-Fos expression in the vlPAG or rVLM in IMH rats. a c-Fos expression in the vlPAG following EA, MA or combined EA + MAMA at Neuro-Sps in IMH rats. b Quantification of c-Fos labeled neurons in vlPAG (shown in a) in each group. Data are expressed as the numbers of c-Fos-positive cells in vlPAG per mm2. c c-Fos expression in the rVLM following EA, MA or combined EA + MA at Neuro-Sps in IMH rats. d Quantification of c-Fos labeled neurons in rVLM in each group. Data are expressed as the numbers of c-Fos-positive cells in rVLM per mm2. Nor normal group without IMH (n = 7); Con control group, IMH only (n = 7); EA, electroacupuncture at Neuro-Sps in IMH rats (n = 8); MA mechanical acupuncture at Neuro-Sps in IMH rats (n = 7); EA + MA, electrical and mechanical acupuncture at Neuro-Sps in IMH rats (n = 7).#P < 0.05 vs. Nor; *P < 0.05 vs. Con.
