摘　　要：刺激腓浅神经诱发皮层单位放电的非时锁反应(N-TLR)可分为兴奋、抑制、无关型,时锁反应(TLR)可分为Ⅰ、Ⅱ、Ⅲ型。N-TLR的兴奋型单位可有Ⅰ、Ⅱ或Ⅲ型TLR,无关型单位也可有Ⅰ、Ⅱ或Ⅲ型TLR,抑制型单位有Ⅰ或Ⅲ型TLR。表明TLR和N-TLR各型的关系比较复杂,两者可能反映不同信息,TLR可能反映更多信息。提示研究体感皮层单位放电对外周刺激的反应时,不仅要分析N-TLR,还要分析TLR,后者可能更为重要。只分析一种就会遗漏许多信息。The non-timc-lock response (N-TLR) and time-lock response (TLR) of 67 unit discharges in somatosensory cortex evoked by nociceptive stimulation of superficial peroneal nerve (P-ED) were analysed quantitatively with microcomputer and compared each other. The results showed that the relationship between N-TLR and TLR of P-ED was rather complicated. N-TLR and TLR contained different informations,but TLR might have more. It is suggested that when the responses to peripheral stimulation are studied not on'ry N-TLR but also TLR should be analysed, and the latter might be more important.
