Different EEG-vigilance stages from full alertness to sleep onset can be separated during rest. Also fMRI research recently focused on the resting condition and identified several resting state networks. In order to deepen the understanding of different levels of global brain function from relaxed wakefulness to sleep onset the association between(More)
Structural and metabolic alterations in prefrontal brain areas, including the subgenual (SGPFC), medial (MPFC) and dorsolateral prefrontal cortex (DLPFC), have been shown in major depressive disorder (MDD). Still it remains largely unknown how brain connectivity within these regions is altered at the level of neuronal oscillations. Therefore, the goal was(More)
Independent component analysis (ICA)-based muscle artefact correction has become a popular tool within electroencephalographic (EEG) research. As a comment on the article by McMenamin et al. (2010), we want to address three issues concerning the claimed lack of sensitivity and specificity of this method. The under- or overestimation of myogenic and(More)
Confronted with increased market dynamics andh ence frequently changing systemenvironments, today's decision support systems face thed emand to respect such developments. Developing and maintaining so called agile business intelligence(BI) systems is am ajor challenge for information technology and organizations , since the underlyinga ssumption of BI is to(More)
Simultaneous acquisition of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) data could offer a much deeper understanding of brain function, e.g. in the analysis of tempo-spatial dynamics of brain activity in cognitive processing. However, more sophisticated analysis methods such as single-trial coupling of EEG and fMRI are(More)
The regulation of brain activation, as assessed with the EEG, is a state modulated trait. A decline to lowered EEG-vigilance states has been found to be associated with emotional instability in older studies, but has not been systematically studied in patients with borderline personality disorder (BPD). Twenty unmedicated BPD patients were compared to 20(More)
OBJECTIVE To investigate influences of EEG-vigilance regulation patterns on perceptual processing during sustained visual attention in early visual areas. METHODS We compared a subject group with stable vigilance regulation to a group with unstable EEG-vigilance regulation. A rapid serial visual presentation stream (RSVP) elicited a 7.5 Hz steady state(More)
Major depressive disorder (MDD) has high population prevalence and is associated with substantial impact on quality of life, not least due to an unsatisfactory time span of sometimes several weeks from initiation of treatment to clinical response. Therefore extensive research focused on the identification of cost-effective and widely available(More)
