Circadian modulation of learning and memory efficiency is an evolutionarily conserved
phenomenon, occurring in organisms ranging from invertebrates to higher mammalian …

Neural activity often becomes rhythmic during mental processing. But there has been no
direct proof that rhythmicity, per se, is important for mental function. We assessed this issue …

It is well established that the occurrence of theta rhythm in the hippocampus is important in a
variety of mnemonic tasks. However, in this review it will be argued that theta-rhythmic …

Human scalp electroencephalographic rhythms, indicative of cortical population synchrony,
have long been posited to reflect cognitive processing. Although numerous studies …

Large-amplitude sleep slow oscillations group faster neuronal oscillations and are of
functional relevance for memory performance. However, relatively little is known about the …

Highlights•The spatiotemporal resolution of ECoG is unmatched in the study of human
cognition.•Memory is linked to patterns of regional synchronization and desynchronization.• …

The circadian system has pronounced influence on learning and memory, manifesting as
marked changes in memory acquisition and recall across the day. From a mechanistic …

Neurons extracted from specific areas of the Central Nervous System (CNS), such as the
hippocampus, the cortex and the spinal cord, can be cultured in vitro and coupled with a …

The idea that synchronous neural activity underlies cognition has driven an extensive body
of research in human and animal neuroscience. Yet, insufficient data on intracranial …

I propose that synchronization affects communication between neuronal groups. Gamma-
band (30–90 Hz) synchronization modulates excitation rapidly enough that it escapes the …
