Task-Aware Information Routing from Common Representation Space in Lifelong Learning (2023, background): “To this end, Global Neuronal Workspace (GNW) hypothesis (Dehaene et al., 1998) posits that brain entails a second computational space composed of widely distributed excitatory neurons that selectively mobilize or suppress, through descending connections, the contribution of specific processor…”
Coordination Among Neural Modules Through a Shared Global Workspace (2021, methodology): “Inspired by the Global Workspace Theory (Baars, 1993; Dehaene et al., 1998; Shanahan and Baars, 2005; Shanahan, 2006; 2010; 2012; Dehaene et al., 2017) from cognitive neuroscience, we argue that more ﬂexibility and generalization emerge through an architecture of specialists if their training encour”
Psychosocial stress reversibly disrupts prefrontal processing and attentional control (2009, unknown): “These dendrites are the target of long-range corticocortical projections and are assumed to play an important computational role in cognitive functions mediated by a distributed network of structures (24).”
EEG and MEG: relevance to neuroscience. (2013, unknown): “proposed by Dehaene et al. (1998). The brain has to integrate distributed sets of neuronal assemblies spread over multiple cortical domains to achieve coherent representation of events and to effectuate coordinated actions. This means that the information processed by any neuronal population has to ”
Affective neuroscience of pleasure: reward in humans and animals (2008, unknown): “Some have even suggested that the orbitofrontal and anterior cingulate cortices could be viewed as part of a global workspace for access to consciousness with the specific role of evaluating the affective valence of stimuli (Dehaene et al. 1998; Kringelbach 2008).”
Brain Dynamics Underlying the Nonlinear Threshold for Access to Consciousness (2007, result): “Our observations are most consistent with the theory of a global workspace formed by multiple distant associative areas including prefrontal, parietal, and temporal cortices [16,19,20].”
Global connectivity of prefrontal cortex predicts cognitive control and intelligence (2012, background): “This would allow for a mechanism by which specific control regions can access and influence other relevant networks (such as sensory-motor networks involved in task-relevant processing) to adaptively monitor and regulate ongoing behavior (Dehaene et al., 1998; Miller and Cohen, 2001).”
Scaling Brain Size, Keeping Timing: Evolutionary Preservation of Brain Rhythms (2013, unknown): “The latter pertains to the ability to integrate a large number of distributed local processes into globally ordered states (Tononi et al., 1998; Dehaene et al., 1998) whereby the results of local computations are broadcast to widespread brain areas so that multiple structures are simultaneously…”
Robot Cognitive Control with a Neurophysiologically Inspired Reinforcement Learning Model (2011, background): “Such a mechanism was inspired by the concept of vigilance employed by Dehaene and Changeux (1998) to modulate the activity ofworkspace neurons whose role is to determine the degree of effort in decision-making.”
On the link between conscious function and general intelligence in humans and machines (2022, background): “In its various formulations, this workspace has been associated with the frontal and parietal cortex and functionally connected to both attentional control and working memory (Dehaene et al., 1998; 2006).”
Global Workspace Theory (GWT) and Prefrontal Cortex: Recent Developments (2021, background): “Stanislas Dehaene and Jean-Pierre Changeux in Paris have developed experimentally testable models and made further testable claims about the brain basis of visual consciousness (Dehaene et al., 1998; Dehaene and Changeux, 2011).”
