Gamma oscillations are thought to temporally link the activity of distributed cells. We discuss mechanisms of gamma oscillations in the hippocampus and review evidence supporting a functional role for such oscillations in several key hippocampal operations, including cell grouping, dynamic routing, and memory. We propose that memory encoding and retrieval are coordinated by different frequencies of hippocampal gamma oscillations and suggest how transitions between slow and fast gamma may occur.
伽马振荡被认为是时间上链接分布式细胞活动的。我们讨论了海马体中伽马振荡的机制，并回顾了支持这种振荡在几个关键海马体操作中的功能作用的证据，包括细胞分组、动态路由和记忆。我们提出记忆的编码和检索是由不同频率的海马体伽马振荡协调的，并提出了慢伽马和快伽马之间如何转换的建议。
