我们以往的工作表明,电针“足三里”可以激活中缝大核(NRM)神经元的放电和抑制伤害性反应;这种效应在电解损毁尾核头部或导水管周围灰质(PAG)后明显减弱。而刺激这两个区域也能激活大多数NRM神经元的自发放电和抑制伤害性反应。表明
Our previous work showed that electroacupuncture “Zusanli” can activate the discharge of NRM neurons and inhibit the nociceptive response; this effect is evident after electrolytic destruction of the caudate nucleus or periaqueductal gray (PAG) Weakened. However, stimulation of these two regions also activated spontaneous firing of most NRM neurons and inhibited nociceptive responses. show
