Journal ArticleDOI
An Evaluation of Cardiorespiratory and Movement Features With Respect to Sleep-Stage Classification
Tim Willemen,D. Van Deun,Vincent Verhaert,M. Vandekerckhove,Vasileios Exadaktylos,Johan Verbraecken,S. Van Huffel,Bart Haex,Jos Vander Sloten +8 more
TL;DR: Evaluating cardiorespiratory and movement signals in discriminating between wake, rapid-eye-movement (REM), light (N1N2), and deep (N3) sleep demonstrated the possibility of making long-term sleep monitoring more widely available.
Journal ArticleDOI
The role of presleep negative emotion in sleep physiology
Marie Vandekerckhove,Rolf Weiss,Christiaan Schotte,Vasileios Exadaktylos,Bart Haex,Johan Verbraecken,Raymond Cluydts +6 more
TL;DR: It is demonstrated that negative emotion correlates with enhanced sleep fragmentation helping to understand why sleep patterns change and how sleep disturbances may develop.
Journal ArticleDOI
Sleep misperception, EEG characteristics and Autonomic Nervous System activity in primary insomnia: A retrospective study on polysomnographic data
Jana Maes,Johan Verbraecken,M. Willemen,I. De Volder,A. Van Gastel,N. Michiels,I Verbeek,Marie Vandekerckhove,Jan Wuyts,Bart Haex,Tim Willemen,Vasileios Exadaktylos,Arnoud Bulckaert,R Cluydts +13 more
TL;DR: The Primary Insomnia-group overestimated Sleep Onset Latency and this overestimation was correlated with elevated EEG activity, and the strong association found between K-alpha (K-complex within one second followed by 8-12 Hz EEG activity) in Stage2 sleep and a lower parasympathetic Autonomic Nervous System dominance (less high frequency HR) in Slow-wave sleep, further assumes a state of hyperarousal continuing through sleep in Primary Ins insomnia.
Journal ArticleDOI
The influence of pre-sleep cognitive arousal on sleep onset processes
Johan Wuyts,Elke De Valck,Marie Vandekerckhove,Nathalie Pattyn,Nathalie Pattyn,Arnoud Bulckaert,Daniel Berckmans,Bart Haex,Johan Verbraecken,Raymond Cluydts +9 more
TL;DR: Pre-sleep cognitive activation successfully induced a significant cognitive load and activation in subjects to influence subsequent sleep (onset) processes and significantly prolonged sleep onset latency in healthy volunteers.
