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

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

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 …

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 …

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 …

Electrophysiological methods are the gold standard in neuroscience because they reveal
the activity of individual neurons at high temporal resolution and in arbitrary brain locations …

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

Over more than a century of research has established the fact that sleep benefits the
retention of memory. In this review we aim to comprehensively cover the field of “sleep and …

Neuronal activity in the brain gives rise to transmembrane currents that can be measured in
the extracellular medium. Although the major contributor of the extracellular signal is the …
