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 …

Network dynamics have been proposed as a mechanistic substrate for the information
transfer across cortical and hippocampal circuits. However, little is known about the …

The coupled interaction between slow-wave oscillations and sleep spindles during non-
rapid-eye-movement (NREM) sleep has been proposed to support memory consolidation …

While the interaction of the cardinal rhythms of non-rapid-eye-movement (NREM) sleep—the
thalamo-cortical spindles, hippocampal ripples, and the cortical slow oscillations—is thought …

Summary Gamma oscillations (∼ 30–150 Hz) are widespread correlates of neural circuit
functions. These network activity patterns have been described across multiple animal …

During systems-level consolidation, mnemonic representations initially reliant on the
hippocampus are thought to migrate to neocortical sites for more permanent storage, with an …

Sleep is universal, tightly regulated, and its loss impairs cognition. But why does the brain
need to disconnect from the environment for hours every day? The synaptic homeostasis …

Consolidation of declarative memories requires hippocampal-neocortical communication.
Although experimental evidence supports the role of sharp-wave ripples in transferring …

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 …
