Neuronal ensembles, defined as groups of neurons displaying recurring patterns of
coordinated activity, represent an intermediate functional level between individual neurons …

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

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 …

Before the onset of locomotion, the hippocampus undergoes a transition into an activity-state
specialized for the processing of spatially related input. This brain-state transition is …

Granule cells in the dentate gyrus of the hippocampus are thought to be essential to memory
function by decorrelating overlap** input patterns (pattern separation). A second …

In mammals, the selective transformation of transient experience into stored memory occurs
in the hippocampus, which develops representations of specific events in the context in …

Following learning, increased coupling between spindle oscillations in the medial prefrontal
cortex (mPFC) and ripple oscillations in the hippocampus is thought to underlie memory …

Sharp-wave ripples (SPW-Rs) in the hippocampus are implied in memory consolidation, as
shown by observational and interventional experiments. However, the mechanism of their …

Spatial memories that can last a lifetime are thought to be encoded during 'online'periods of
exploration and subsequently consolidated into stable cognitive maps through their …
