伤害性刺激诱发体感皮层单位放电的时锁反应和非时锁反应

NON-TIME-LOCK AND TIME-LOCK RESPONSES OF UNIT DISCHARGES IN SOMATOSENSORY CORTEX EVOKED BY NOXIOUS STIMULATION

应用微机对刺激外周神经诱发体感皮层单位放电(P-ED)的时锁反应(TLR)和非时锁反应(N-TLR)进行定量分析,互相比较。结果表明TLR和N-TLR的关系比较复杂,两者反映不同信息,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-time-lock response ( N-TLR ) and time-lock response ( TLR ) of 73 unit discharges in somatosensory cortex evoked by nociceptive stimulation of peripheral nerve (P-ED) were analysed quantitatively with micro-computer and compared each other. The results showed that the relationship between the N-TLR and TLR of P-ED was rather complicated. N-TLR and TLR contained different information, but TLR might has more. It was suggested that when studying the responses to peripheral stimulation not only N-TLR but also TLR should be analysed, and the latter one might be more important.
