Breakdown in cortical effective connectivity during midazolam-induced loss of consciousness
By employing transcranial magnetic stimulation (TMS) in combination with high-density
electroencephalography (EEG), we recently reported that cortical effective connectivity is …

[HTML][HTML] Level of consciousness is dissociable from electroencephalographic measures of cortical connectivity, slow oscillations, and complexity
Leading neuroscientific theories posit a central role for the functional integration of cortical
areas in conscious states. Considerable evidence supporting this hypothesis is based on …

Hierarchical clustering of brain activity during human nonrapid eye movement sleep
M Boly, V Perlbarg, G Marrelec… - Proceedings of the …, 2012 - National Acad Sciences
Consciousness is reduced during nonrapid eye movement (NREM) sleep due to changes in
brain function that are still poorly understood. Here, we tested the hypothesis that impaired …
