At any one moment, many neuronal groups in our brain are active. Microelectrode
recordings have characterized the activation of single neurons and fMRI has unveiled brain-wide …

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

Neuronal gamma-band synchronization is found in many cortical areas, is induced by different
stimuli or tasks, and is related to several cognitive capacities. Thus, it appears as if many …

This Perspective considers the influential notion of a canonical (cortical) microcircuit in light
of recent theories about neuronal processing. Specifically, we conciliate quantitative studies …

Classical theories of sensory processing view the brain as a passive, stimulus-driven device.
By contrast, more recent approaches emphasize the constructive nature of perception, …

In crowded visual scenes, attention is needed to select relevant stimuli. To study the underlying
mechanisms, we recorded neurons in cortical area V4 while macaque monkeys attended …

Activated neuronal groups typically engage in rhythmic synchronization in the gamma-frequency
range (30–100Hz). Experimental and modeling studies demonstrate that each gamma …

This paper describes FieldTrip, an open source software package that we developed for the
analysis of MEG, EEG, and other electrophysiological data. The software is implemented as …

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

In this review, we consider the potential functional role of beta-band oscillations, which at
present is not yet well understood. We discuss evidence from recent studies on top-down …
