Various cognitive functions have long been known to require the hippocampus. Recently,
progress has been made in identifying the hippocampal neural activity patterns that …

Modern optogenetics can be tuned to evoke activity that corresponds to naturally occurring
local or global activity in timing, magnitude or individual-cell patterning. This outcome has …

Sharp wave ripples (SPW‐Rs) represent the most synchronous population pattern in the
mammalian brain. Their excitatory output affects a wide area of the cortex and several …

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 …

Acetylcholine (AC h) plays an important role in memory function and has been implicated in
aging‐related dementia, in which the impairment of hippocampus‐dependent learning …

In the hippocampus GABAergic local circuit inhibitory interneurons represent only~ 10–15%
of the total neuronal population; however, their remarkable anatomical and physiological …

The mammalian hippocampus is important for normal memory function, particularly memory
for places and events. Place cells, neurons within the hippocampus that have spatial …

This review focuses on the neuronal and circuit mechanisms involved in the generation of
the theta (θ) rhythm and of its participation in behavior. Data have accumulated indicating …

Brain activity during sleep is characterized by circuit-specific oscillations, including slow
waves, spindles and theta waves, which are nested in thalamocortical or hippocampal …

The hippocampus is crucial for episodic memory, but it is also involved in online prediction.
Evidence suggests that a unitary hippocampal code underlies both episodic memory and …
