一篇新文章指出: 海马区的 长时程增强(long-term potentiation;LTP;一种学习和记忆的形式)可以诱导“ 起 陡峭波复合体”(sharp wave-ripple complex); 起 陡峭波复合体被认为是对皮层 记忆痕迹(memory trace)的稳定有重要贡献的。
(Figure 1. Self-organized burst of activity in the hippocampal CA3 region produces a field potential in the dendritic layer of CA1 and a short-lived fast-frequency field oscillation (200-Hz ripple) within stratum pyramidale, as well as a phase-related discharge of the neurons. )
