一篇新文章指出：海馬區的長時程增強（long-term potentiation；LTP；一種學習和記憶的形式）可以誘導“起陡峭波復合體”（sharp wave-ripple complex）；起陡峭波復合體被認為是對皮層記憶痕跡（memory trace）的穩定有重要貢獻的。
(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.)
