摘要

基于抗痛觉性治疗(如全身阿片或导水管周围灰质刺激)不能调节5 -羟色胺能神经元的放电速率,有人提出5 -羟色胺能神经元不介导阿片镇痛。然而,关于支持这一假设的数据,有几点需要澄清。这些包括确定麻醉是否影响了这些实验的结果,记录的血清素能神经元是否投射到背角,以及突触前效应是否允许阿片类药物改变血清素的释放而不改变神经元的放电速率

The role of serotonergic neurons in nucleus raphe magnus in opioid antinociception

It has been proposed that serotonergic neurons do not mediate opioid analgesia, based on the observation that the firing rates of serotonergic neurons are not modulated by antinociceptive treatments such as systemic opioids or periaqueductal gray (PAG) stimulation. However, several points need to be clarified regarding the data supporting this hypothesis. These include establishing whether anesthesia has influenced the results of these experiments, whether the serotonergic neurons recorded project to the dorsal horn, and whether presynaptic effects might allow opioids to change serotonin release without changing neuronal firing rate
