The hippocampal local field potential (LFP) shows three major types of rhythms: theta, sharp wave–ripples and gamma. These rhythms are defined by their frequencies, they have behavioural correlates in several species including rats and humans, and they have been proposed to carry out distinct functions in hippocampal memory processing. However, recent findings have challenged traditional views on these behavioural functions. In this Review, I discuss our current understanding of the origins and the mnemonic functions of hippocampal theta, sharp wave–ripples and gamma rhythms on the basis of findings from rodent studies. In addition, I present an updated synthesis of their roles and interactions within the hippocampal network.

• Temporal Interference Stimulation Enhances Neural Regeneration (2026, unknown): “These stimulation parameters were selected using a biomimetic approach, replicating typical hippocampal endogenous frequencies (theta, gamma, and delta) with longer activity patterns than in development (10s ON-10s OFF stimulation blocks) [ 75 ].”
• Dynamic internal states shape memory retrieval. (2019, unknown): “Different phases of theta may be optimal for encoding and retrieval, in line with a state-based account of hippocampal function (Colgin, 2016; Kerrén, Linde-Domingo, Hanslmayr, & Wimber, 2018).”
