【摘要】 在32只大鼠的中缝大核内共记录到225个神经元自发放电。其中,痛相关神经元占58％。观察了剌激红核对160个中缝大核神经元自发放电频率的影响,其中,起兴奋作用的占59％。特别是对痛兴奋神经元起兴奋作用的就占68％。刺激红核对中缝大核神经元的兴奋作用在一定范围内与剌激强度、频率和持续时间呈正变关系。结果表明,红核除有调节躯体运动的机能外,还可能通过中缝大核对感觉传入起调制作用。更多还原

【Abstract】 The spontaneous discharges of 225 neurons in NRM were recorded in 32 rats and the majority(58%) of them were pain-relative neurons.It was observed in 160 neurons that stimulation of RN could excite 59% of NRM neurons,especially the pain-excitatory neurons (49/72, 68%). The excitatory effect could be influenced by different stimulation parameters applied to RN.更多还原
