Summary Gamma oscillations (∼ 30–150 Hz) are widespread correlates of neural circuit
functions. These network activity patterns have been described across multiple animal …

INTRODUCTION Learning induces a dynamic reorganization of brain circuits but the
neuronal mechanisms underlying this process are not well understood. Interregional gamma …

The consolidation of spatial memory depends on the reactivation ('replay') of hippocampal
place cells that were active during recent behaviour. Such reactivation is observed during …

GABAergic inhibitory circuits play an essential role in coordinating various hippocampal
functions. Several decades of work dedicated to a thorough characterization of hippocampal …

Episodic memory involves learning and recalling associations between items and their
spatiotemporal context. Those memories can be further used to generate internal models of …

Hippocampal sharp wave ripples (SPW-Rs) have been hypothesized as a mechanism for
memory consolidation and action planning. The duration of ripples shows a skewed …

The incorporation of new information into the hippocampal network is likely to be
constrained by its innate architecture and internally generated activity patterns. However, the …

The relationship between mesoscopic local field potentials (LFPs) and single-neuron firing
in the multi-layered neocortex is poorly understood. Simultaneous recordings from all layers …

Traditionally considered a homogeneous cell type, hippocampal pyramidal cells have been
recently shown to be highly diverse. However, how this cellular diversity relates to the …
