Memory reactivations and replay, widely reported in the hippocampus and cortex across
species, have been implicated in memory consolidation, planning, and spatial and skill …

There is a demand for noninvasive methods to ameliorate disease. We investigated whether
40-Hz flickering light entrains gamma oscillations and suppresses amyloid-β in the brains of …

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

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

Sleep is pivotal for memory consolidation. According to two-stage accounts, memory traces
are gradually translocated from hippocampus to neocortex during non-rapid-eye-movement …

The hippocampus is composed of various subregions: CA1, CA2, CA3, and the dentate
gyrus (DG). Despite the abundant hippocampal research literature, until recently, CA2 …

Associative memory enables the encoding and retrieval of relations between different
stimuli. To better understand its neural basis, we investigated whether associative memory …

Hippocampus–neocortex interactions during sleep are critical for memory processes:
Hippocampally initiated replay contributes to memory consolidation in the neocortex and …

The hippocampus is thought to guide navigation by forming a cognitive map of space.
Different environments differ in geometry and the availability of cues that can be used for …
