A recent study using intracerebral electroencephalography (EEG) recordings in human patients has documented the electrophysiological correlates of conscious reporting of near-threshold visual targets that followed supra-threshold peripheral spatial cues. Here, we aimed to bridge these intracerebral EEG events with corresponding surface recording, differentiating between conscious and...
How do attention and consciousness interact in the human brain? Rival theories of consciousness disagree on the role of fronto-parietal attentional networks in conscious perception. We recorded neural activity from 727 intracerebral contacts in 13 epileptic patients, while they detected near-threshold targets preceded by attentional cues. Clustering revealed three neural patterns: first,...

We developed a new rodent model of reversible brain anoxia and performed continuous electrocorticographic (ECoG) and intracellular recordings of neocortical neurons to identify in real-time the cellular and network dynamics that successively emerge throughout the dying-to-recovery process. Along with a global decrease in ECoG amplitude, deprivation of oxygen supply resulted in an early surge of...
The purpose of this paper is to show through the concrete example of epileptic seizure anticipation how neuro-dynamic analysis (using new mathematical tools to detect the dynamic structure of the neuro-electric activity of the brain) and "pheno-dynamic" analysis (using new interview techniques to detect the pre-reflective dynamic micro-structure of the corresponding subjective experience) may...
