Sleep misperception, EEG characteristics and Autonomic Nervous System activity in primary insomnia: A retrospective study on polysomnographic data

TLDR
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.

The neurobiology, investigation, and treatment of chronic insomnia

TL;DR: Family and twin studies confirm that chronic insomnia can have a genetic component (heritability coefficients between 42% and 57%), whereas the investigation of autonomous and central nervous system parameters has identified hyperarousal as a final common pathway of the pathophysiology.
Journal ArticleDOI

Heart rate variability in insomnia patients: A critical review of the literature

TL;DR: It is unable to confirm that HRV is reliably impaired in insomnia patients nor determine the HRV response to interventions, due to considerable differences in patient (and control) selection, study protocols, measurement and processing techniques and outcome reporting.
Journal ArticleDOI

Regional homogeneity changes in patients with primary insomnia

TL;DR: The authors' study found abnormal spontaneous activities in multiple brain regions, especially in emotion-related areas in PI patients, which might contribute to an understanding the intrinsic functional architecture of insomnia and its clinical features.

Regional Patterns of Elevated Alpha and High-Frequency Electroencephalographic Activity during Nonrapid Eye Movement Sleep in Chronic Insomnia: A Pilot Study

TL;DR: These results suggest that even during the deepest stage of sleep, sensory and sensorimotor areas in insomnia subjects may still be relatively active compared to control subjects and to the rest of the sleeping brain.
Journal ArticleDOI

Combining electroencephalographic activity and instantaneous heart rate for assessing brain-heart dynamics during visual emotional elicitation in healthy subjects.

TL;DR: Electroencephalographic dynamics and instantaneous heart rate estimates combined to study emotional processing in healthy subjects found high arousing elicitations seem to mitigate changes in brain–heart dynamics in response to pleasant/unpleasant visual elicitation.
