Although long-term memory consolidation is supported by sleep, it is unclear how it differs
from that during wakefulness. Our review, focusing on recent advances in the field, identifies …

The spontaneous replay of patterns of activity related to past experiences and memories is a
striking feature of brain activity, as is the coherent activation of sets of brain areas …

Episodic memory reflects the ability to recollect the temporal and spatial context of past
experiences. Episodic memories depend on the hippocampus but have been proposed to …

Resting-state functional magnetic resonance imaging (fMRI) has highlighted the rich
structure of brain activity in absence of a task or stimulus. A great effort has been dedicated …

Conscious memory for a new experience is initially dependent on information stored in both
the hippocampus and neocortex. Systems consolidation is the process by which the …

Many attempts have been made to localize the physical trace of a memory, or engram, in the
brain. However, until recently, engrams have remained largely elusive. In this Review, we …

Experiences need to be tagged during learning for further consolidation. However,
neurophysiological mechanisms that select experiences for lasting memory are not known …

INTRODUCTION The hippocampus plays an important role in memory and spatial
navigation. When rodents navigate a spatial maze, hippocampal neurons called place cells …

Our daily lives unfold continuously, yet when we reflect on the past, we remember those
experiences as distinct and cohesive events. To understand this phenomenon, early …

The last decade has seen dramatic technological and conceptual changes in research on
episodic memory and the brain. New technologies, and increased use of more naturalistic …
