Reliable local dynamics in the brain across sessions are revealed by whole-brain modeling of resting state activity
(Wiley-liss, div John Wiley & Sons Inc., 2019-03)
Resting state fMRI is a tool for studying the functional organization of the human brain. Ongoing brain activity at “rest” is highly dynamic, but procedures such as correlation or independent component analysis treat ...
Perturbation of whole-brain dynamics in silico reveals mechanistic differences between brain states
(Academic Press, 2018-04)
Human neuroimaging research has revealed that wakefulness and sleep involve very different activity patterns. Yet, it is not clear why brain states differ in their dynamical complexity, e.g. in the level of integration and ...
Sleep in brain development

Brain Organization into Resting State Networks Emerges at Criticality on a Model of the Human Connectome
(Amer Physical Soc, 2013-04-26)
The relation between large-scale brain structure and function is an outstanding open problem in neuroscience. We approach this problem by studying the dynamical regime under which realistic spatiotemporal patterns of brain ...
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 ...
Awakening: Predicting external stimulation to force transitions between different brain states
(National Academy of Sciences, 2019-09)
A fundamental problem in systems neuroscience is how to force a transition from one brain state to another by external driven stimulation in, for example, wakefulness, sleep, coma, or neuropsychiatric diseases. This requires ...
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 ...
Active neural coordination of motor behaviors with internal states
(Proceedings of the National Academy of Sciences, 2022)
Evolution and the Relationship between brain and mind states
(Human Sciences Press, Ine., 1996)
We discuss the phylogenetic basis of states of consciousness,
and present the central theses of monism and dualism, in which near-death
experiences (NDEs) enjoy very different ontological statuses. Next, we summarize
the ...
