配对脉冲刺激具有两种相反的反应类型:双脉冲易化(paired-pulse facilitation;PPF)和双脉冲抑制(paired pulse depression;PPD)(如图2)。Bryan Krause认为在这两种反应中,第二次脉冲后的钙浓度都高于第一次脉冲后的钙浓度。 图2 来源:参考资料[1] paired-pulse facilitation,PPF,双脉冲易化 当施加两个连续脉冲时,第二...

Participants were instructed to press as quickly and accurately as possible on the key associated with the color of the word, while ignoring the word's meaning. Stroop bias scores were computed as the difference in mean reaction times (RT) between incongruent and congruent conditions, excluding ...
采用双脉冲刺激比率(paired-pulse ratio,PPR,一个用于验证突触前递质释放概率变化的电生理指标)的实验证实,SNL小鼠NAc壳区MSNs记录到的EPSCs的PPR值显著增加,IPSC的PPR值减小。 前期研究显示,SNL引起的神经病理性疼痛同时也导致NAc区趋化因子CCL2及受体CCR2表达和活动增加,并且参与MSN兴奋性突触传递效率的调节。为了...
