Journal ArticleDOI
Simultaneous Electroencephalographic and Functional Magnetic Resonance Imaging Indicate Impaired Cortical Top–Down Processing in Association with Anesthetic-induced Unconsciousness
Denis Jordan,Rüdiger Ilg,Valentin Riedl,Anna Schorer,Sabine Grimberg,Susanne Neufang,Adem Omerovic,Sebastian Berger,Gisela Untergehrer,Christine Preibisch,Enrico Schulz,Tibor Schuster,Manuel Schröter,Victor I. Spoormaker,Claus Zimmer,Bernhard Hemmer,Afra M. Wohlschläger,Eberhard Kochs,Gerhard Schneider +18 more
TL;DR: The simultaneous propofol-induced suppression of frontal feedback connectivity in the electroencephalogram and of frontoparietal FC in the fMRI indicates a fundamental role of top–down processing for consciousness.
Journal ArticleDOI
Spatiotemporal Reconfiguration of Large-Scale Brain Functional Networks during Propofol-Induced Loss of Consciousness
Manuel Schröter,Victor I. Spoormaker,Anna Schorer,Afra M. Wohlschläger,Michael Czisch,Eberhard Kochs,Claus Zimmer,Bernhard Hemmer,Gerhard Schneider,Denis Jordan,Rüdiger Ilg +10 more
TL;DR: A profound decline in long-range connections and a reduction in whole-brain spatiotemporal integration are observed, supporting a topological reconfiguration during PI-LOC and shed light on the functional significance of intrinsic brain activity as measured by spontaneous BOLD signal fluctuations.
Journal ArticleDOI
Neural Correlates of Sevoflurane-induced Unconsciousness Identified by Simultaneous Functional Magnetic Resonance Imaging and Electroencephalography.
Andreas Ranft,Daniel Golkowski,Tobias Kiel,Valentin Riedl,Philipp Kohl,Guido Rohrer,Joachim Pientka,Sebastian Berger,Alexander Thul,Max Maurer,Christine Preibisch,Claus Zimmer,George A. Mashour,Eberhard Kochs,Denis Jordan,Rüdiger Ilg +15 more
TL;DR: Understanding of sevoflurane-induced unconsciousness is advanced and the changes in blood oxygenation level dependent connectivity were consistent with reduced anterior-to-posterior directed connectivity and reduced cortical information processing.
Journal ArticleDOI
Electroencephalographic Order Pattern Analysis for the Separation of Consciousness and Unconsciousness : An Analysis of Approximate Entropy, Permutation Entropy, Recurrence Rate, and Phase Coupling of Order Recurrence Plots
TL;DR: In this article, the hypnotic component of anesthesia was measured by permutation entropy, recurrence rate, and phase coupling of order recurrence plots, which are suitable for any type of time series, whether deterministic or noisy.
Journal ArticleDOI
EEG entropy measures indicate decrease of cortical information processing in Disorders of Consciousness.
Alexander Thul,Julia Lechinger,Johann Donis,Gabriele Michitsch,Gerald Pichler,Eberhard Kochs,Denis Jordan,Rüdiger Ilg,Manuel Schabus +8 more
TL;DR: Local EEG information content and information flow are affected in Disorders of Consciousness, which suggests local cortical information capacity and feedback information transfer as neural correlates of consciousness.
