We review the central tenets and neuroanatomical basis of the global neuronal workspace
(GNW) hypothesis, which attempts to account for the main scientific observations regarding …

The brain must dynamically integrate, coordinate, and respond to internal and external
stimuli across multiple time scales. Non-invasive measurements of brain activity with fMRI …

At rest, the brain is traversed by spontaneous functional connectivity patterns. Two
hypotheses have been proposed for their origins: they may reflect a continuous stream of …

The experiences induced by psychedelics share a wide variety of subjective features,
related to the complex changes in perception and cognition induced by this class of drugs. A …

Human imaging studies have shown that spontaneous brain activity exhibits stereotypic
spatiotemporal reorganization in awake, conscious conditions with respect to minimally …

Despite advances in resting state functional magnetic resonance imaging investigations,
clinicians remain with the challenge of how to implement this paradigm on an individualized …

Resting-state (RS) functional magnetic resonance (MR) imaging constitutes a novel
paradigm that examines spontaneous brain function by using blood oxygen level …

Introduction Directional connectivity from anterior to posterior brain regions (or “feedback”
connectivity) has been shown to be inhibited by the gamma-aminobutyric acid agonists …

To understand how pharmacological interventions can exert their powerful effects on brain
function, we need to understand how they engage the brain's rich neurotransmitter …

This review focuses on resting-state functional connectivity, a functional MRI technique
which allows the study of spontaneous brain activity generated under resting conditions …
