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.

Journal ArticleDOI
Heart rate-based nighttime awakening detection
Arnoud Bulckaert,Vasileios Exadaktylos,Guido De Bruyne,Bart Haex,Elke De Valck,Johan Wuyts,Johan Verbraecken,Daniel Berckmans +7 more
TL;DR: An algorithm for detection of nighttime awakenings based on heart rate was developed and it was found that heart rate is an adequate measure that allows for Detection of nighttime awakeningings and hence sleep quality.
Journal ArticleDOI
Elevated variance in heart rate during slow-wave sleep after late-night physical activity.
Arnoud Bulckaert,Vasileios Exadaktylos,Bart Haex,Elke De Valck,Johan Verbraecken,Daniel Berckmans +5 more
TL;DR: Exercise up to 1 h before bedtime seems to modify the quality of sleep, with increased mean heart rate and higher LF/HF ratio related to decreased parasympathetic dominance.
