Brains at rest generate dynamical activity that is highly structured in space and time. We
suggest that spontaneous activity, as in rest or dreaming, underlies top-down dynamics of …

We often assume that the variables of functional and structural brain parameters—such as
synaptic weights, the firing rates of individual neurons, the synchronous discharge of neural …

INTRODUCTION In the absence of sensory inputs, the brain produces structured patterns of
activity, which can be as large as or larger than sensory-driven activity. Ongoing activity …

The alpha rhythm is the longest-studied brain oscillation and has been theorized to play a
key role in cognition. Still, its physiology is poorly understood. In this study, we used …

Sensory areas are spontaneously active in the absence of sensory stimuli. This
spontaneous activity has long been studied; however, its functional role remains largely …

Synchronous rhythms represent a core mechanism for sculpting temporal coordination of
neural activity in the brain-wide network. This review focuses on oscillations in the cerebral …

The brain continuously adapts its processing machinery to behavioural demands. To
achieve this, it rapidly modulates the operating mode of cortical circuits, controlling the way …

Switches between different behavioral states of the animal are associated with prominent
changes in global brain activity, between sleep and wakefulness or from inattentive to …

A central feature of human brain activity is the alpha rhythm: a 7–13 Hz oscillation observed
most notably over occipitoparietal brain regions during periods of eyes‐closed rest. Alpha …

Anatomical studies demonstrate that excitatory connections in cortex are not uniformly
distributed across a network but instead exhibit clustering into groups of highly connected …
