Long-term memory formation is a major function of sleep. Based on evidence from
neurophysiological and behavioral studies mainly in humans and rodents, we consider the …

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 …

Learning and plasticity rely on fine-tuned regulation of neuronal circuits during offline
periods. An unresolved puzzle is how the sleeping brain, in the absence of external …

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

Memory consolidation during sleep is thought to depend on the coordinated interplay
between cortical slow waves, thalamocortical sleep spindles and hippocampal ripples, but …

Sleep spindles are burstlike signals in the electroencephalogram (EEG) of the sleeping
mammalian brain and electrical surface correlates of neuronal oscillations in thalamus. As …

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 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 …

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 …
