Our aim with this research program is to understand (1) cognitive processes during sleep onset, (2) (advanced, functional) EEG-correlates of sleep onset, (3) their interaction and (4) how these relate to the resting state.

Outcome measures
Primary outcome
Characterize and relate EEG, RSQ50 scores and their interaction during sleep
onset and resting wakefulness.
Secondary outcome
Extract relevant EEG and cognitive parameters that can be used to successfully
predict sleep onset and/or provide feedback on.
Background summary
Insomnia is a prevalent disorder that is frequently pharmacologically treated.
Hallmark of the disorder is the inability to fall and/or stay asleep, which is
often accompanied by cognitive hyperarousal. Knowing more about the cognitive
and EEG predictors of the sleep onset period may help characterize the disorder
further and also derive more effective strategies to guide subjects towards
more efficient sleep. Furthermore, mapping EEG and cognitive correlates will
potentially guide the development of alternative treatment methods such as
EEG-based biofeedback.
Study objective
Our aim with this research program is to understand (1) cognitive processes
during sleep onset, (2) (advanced, functional) EEG-correlates of sleep onset,
(3) their interaction and (4) how these relate to the resting state.
Study design
Nine sessions of sleep onset matched to nine sessions of wakefulness, simialr
to the protocol employed by Raymann et al. (2005). Each session is recorded
using high-density EEG and followed by the RSQ50 (Linkenkaer-Hansen, 2011).
Study burden and risks
Subjects will visit the lab on two consecutive days. Each day nine measurements
will be made, which will alltogether last a maximum of 8 hours. During each
measurement the subject will be lying in a comfortable bed for a maximum of 30
minutes. Afterwards a computerized version of the questionnaire will be
administered. Mounting of the EEG-cap will take 45 minutes in total, the cap
itself consist of 256 sensors, distributing the weight of the head comfortably.
Preparation of the subject only entails washing the hair * no other possibly
discomforting actions (e.g. skin scrubbing etc.) are necessary. We judge
subject discomfort to be minimal.
