Whole-Brain Models to Explore Altered States of Consciousness from the Bottom Up
(MDPI, 2020)
The scope of human consciousness includes states departing from what most of us experience as ordinary wakefulness. These altered states of consciousness constitute a prime opportunity to study how global changes in brain ...
Whole-brain models to explore altered states of consciousness from the bottom up
(Molecular Diversity Preservation International, 2020-09)
The scope of human consciousness includes states departing from what most of us experience as ordinary wakefulness. These altered states of consciousness constitute a prime opportunity to study how global changes in brain ...
The signatures of conscious access and its phenomenology are consistent with large-scale brain communication at criticality
(Elsevier, 2017-10)
Conscious awareness refers to information processing in the brain that is accompanied by subjective, reportable experiences. Current models of conscious access propose that sufficiently strong sensory stimuli ignite a ...
The dynamical signature of conscious processing: From modality-specific percepts to complex episodes
(2017-01-01)
The search for neural correlates of human consciousness in past decades has been based on different assumptions and methods. Some researchers assume that conscious functions are localized in brain circuits, and ultimately ...
Signature of consciousness in the dynamics of resting-state brain activity
(National Academy Of Sciences, 2015-01)
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 ongoing cognitive processes as well as random ...
Loss of consciousness is associated with stabilization of cortical activity
(Society for Neuroscience, 2015-07)
What aspects of neuronal activity distinguish the conscious from the unconscious brain? This has been a subject of intense interest and debate since the early days of neurophysiology. However, as any practicing anesthesiologist ...
From brain-body function to conscious interactions
In this review, we discuss empirical results inspiring the introduction of a formal mathematical multilayer model for the biological neuroscience of conscious experience. First, we motivate the discussion through evidence ...
Large-scale signatures of unconsciousness are consistent with a departure from critical dynamics
(The Royal Society, 2016-01)
Loss of cortical integration and changes in the dynamics of electrophysiological brain signals characterize the transition from wakefulness towards unconsciousness. In this study, we arrive at a basic model explaining these ...
Spectral signatures of serotonergic psychedelics and glutamatergic dissociatives
(Elsevier, 2019-10-15)
Classic serotonergic psychedelics are remarkable for their capacity to induce reversible alterations in consciousness of the self and the surroundings, mediated by agonism at serotonin 5-HT2A receptors. The subjective ...
