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.)
