| 摘 要： | 使用幼年大鼠视皮层脑片标本23例观察了LTP的发生比率（48%）、最大幅值（580%）、形成潜伏期（14-26min)、及达峰值时间（平均56min)。此外，对双眼视觉剥夺的4例大鼠LTP形成特征进行了初步观察。

| Abstract: | In visual cortex slice-preparation from 23 young rats,some characteristics of LTP have been observed.The results show that the percentage of induced LTP is 48%,the maximum amplitude of LTP is 580%of baseline,the latencv of LTP formation is 14-26min.and the average time reaching the LTP is 56 min.In addition,the features of LTP development of 4 visually deprived young rats have been preliminary investigated. |
