Brief Summary
Sleep slow waves (SSW) and the pathophysiological mechanisms of spike generation in patients with epilepsy are tightly linked. SSW are cortically generated oscillations (\~1 Hz) alternating between a hyperpolarized down-state (neuronal silence) and a depolarized up-state (neuronal firing). It has been shown experimentally that with increasing synchrony of slow neuronal oscillations, spike wave occurrence is facilitated. Auditory stimulation applied in correspondence to the SSW "up-phase" may increase the amplitude of the following SSW. Contrarywise, tones applied at the SSW "down-phase" may have a disruptive effect on SSW. Participants: Patients with epilepsy with epileptic discharges in their sleep EEG, as well as healthy controls Objective: Characterizing the effects of down-phase-targeted auditory stimulation on behavior and sleep EEG characteristics and determine whether the changes in sleep EEG characteristics are associated with the changes in behavior and wake EEG characteristics.

Outcome Measures
Primary Outcomes (2)
CLAS on EEG characteristics & behavior
CLAS changes sleep EEG characteristics (slow-wave and spindle activity) and the measured behavior (e.g. cognitive, memory and motor performance).
Up to 4 years

The changes in sleep EEG characteristics (slow-wave and spindle activity) correlate with the changes in measured behavior (attention \[TAP battery\], reaction time \[TAP battery\], and declarative \[word-pair memory task\] \& spatial memory \[object-location task\]) and wake EEG characteristics (frequencies up to 40 Hz).
Up to 4 years

- Access Criteria
- Ideally, the investigators would like to publish the data through the University of Zurich, which is currently in the process of developing and contributing to the SWISSUbase. Unfortunately, at this time, the repository for neural, biological or psychology data has not yet been created. If, by the time of publication, this is still unavailable, the investigators will choose a repository that is compliant with the FAIR principles such as OpenNeuro. At the end of the project the investigators will evaluate the infrastructures available; it is conceivable that a Swiss university resource, or more suitable repository, will be established by then.
Voluntary approval of the participant or legal guardian of the participant is given by signed informed consent. Personal data will be collected and immediately coded to provide strict confidentiality. The participant code will only be available to the principal investigator and research coordinators. The EEG data, completely anonymized, will be made publicly available to be used in other studies, for which the participant must provide separate consent. The investigators comply with all legal provisions of the Data Protection Act. The data, fully anonymized, will be published in a dedicated online repository. The data includes * PSG data + CLAS triggers * Basic demographic information: gender, age, socioeconomic status, handedness * Chronotype score * Responses to behavioral tests * Actigraphy * Sleep quality and sleepiness scores
