Zero-lag synchronization between distant cortical areas has been observed in a diversity of
experimental data sets and between many different regions of the brain. Several …

Understanding the mechanistic bases of neuronal synchronization is a current challenge in
quantitative neuroscience. We studied this problem in two putative cellular pacemakers of …

The electroencephalogram (EEG) bears the possibility to investigate oscillatory processes in
the human brain. In the animal brain it has been shown that the phase of cortical oscillations …

High-frequency oscillations in cortical networks have been linked to a variety of cognitive
and perceptual processes. They have also been recorded in small cortical slices in vitro …

Neuronal oscillations have been hypothesized to play an important role in cognition and its
ensuing behavior, but evidence that links a specific neuronal oscillation to a discrete …

Memory formation is hypothesized to involve the generation of event-specific neural activity
patterns during learning and the subsequent spontaneous reactivation of these patterns …

Synchronized firing among neurons in the working brain is inferred to reflect coding by cell
assemblies, which dynamically change their sizes and functional connections to encode …

Inter-areal synchronization of neuronal oscillations at frequencies below~ 100 Hz is a
pervasive feature of neuronal activity and is thought to regulate communication in neuronal …

Brain processing depends on the interactions between neuronal groups. Those interactions
are governed by the pattern of anatomical connections and by yet unknown mechanisms …

Spatial attention amplifies the neural response, ie spike rates, brain metabolism, and
oscillatory activity at gamma frequency (beyond 30 Hz). In this study we show that when a …
