  1. Effect of Acoustic fMRI-Scanner Noise on the Human Resting State

    Our knowledge about the human resting state is predominantly based on either electroencephalographic (EEG) or functional magnetic resonance imaging...

    Matthias Grieder, Thomas Koenig in Brain Topography
    Article Open access 19 December 2022

  2. EEG Microstate Dynamics Associated with Dream-Like Experiences During the Transition to Sleep

    Consciousness always requires some representational content; that is, one can only be conscious about something. However, the presence of conscious...

    Sarah Diezig, Simone Denzer, ... Thomas Koenig in Brain Topography
    Article Open access 19 November 2022

  3. Impact of brain arousal and time-on-task on autonomic nervous system activity in the wake-sleep transition

    Background

    Autonomic nervous system (ANS) activity has been shown to vary with the state of brain arousal. In a previous study, this association of...

    Jue Huang, Christine Ulke, ... Tilman Hensch in BMC Neuroscience
    Article Open access 11 April 2018

  4. Brain arousal regulation and depressive symptomatology in adults with attention-deficit/hyperactivity disorder (ADHD)

    Background

    The aim of the present study was to evaluate the stability of brain arousal in adult attention-deficit/hyperactivity disorder (ADHD)...

    Jue Huang, Christine Ulke, Maria Strauss in BMC Neuroscience
    Article Open access 20 August 2019

  5. Evoked potentials and behavioral performance during different states of brain arousal

    Background

    Previous studies compared evoked potentials (EPs) between several sleep stages but only one uniform wake state. However, using...

    Jue Huang, Tilman Hensch, ... Ulrich Hegerl in BMC Neuroscience
    Article Open access 25 January 2017

  6. Tobacco use is associated with reduced amplitude and intensity dependence of the cortical auditory evoked N1-P2 component

    Rationale

    Tobacco use is linked to cerebral atrophy and reduced cognitive performance in later life. However, smoking-related long-term effects on...

    Philippe Jawinski, Nicole Mauche, ... Tilman Hensch in Psychopharmacology
    Article 17 March 2016

  7. Time perception at different EEG-vigilance levels

    Background

    Human time perception is influenced by various factors such as attention and drowsiness. Nevertheless, the impact of cerebral vigilance...

    Juliane Minkwitz, Maja U Trenner, ... Hubertus Himmerich in Behavioral and Brain Functions
    Article Open access 21 September 2012

  8. Separation of Low-Voltage EEG-Activity During Mental Activation from that During Transition to Drowsiness

    When dealing with electroencephalograms (EEGs) recorded under resting conditions, periods of low-voltage activity might indicate drowsiness, but...

    Johannes Jödicke, Sebastian Olbrich, ... Ulrich Hegerl in Brain Topography
    Article 06 April 2013

  9. Prestimulus vigilance predicts response speed in an easy visual discrimination task

    Background

    Healthy adults show considerable within-subject variation of reaction time (RT) when performing cognitive tests. So far, the...

    Juliane Minkwitz, Maja U Trenner, ... Hubertus Himmerich in Behavioral and Brain Functions
    Article Open access 05 August 2011
