Development of a method to compensate for signal quality variations in repeated auditory event-related potential recordings.

Reliable measurements are mandatory in clinically relevant auditory event-related potential (AERP)-based tools and applications. The comparability of the results gets worse as a result of variations in the remaining measurement error. A potential method is studied that allows optimization of the length of the recording session according to the concurrent quality of the recorded data.

Automatic blink detection: a method for differentiation of wake and sleep of intellectually disabled and healthy subjects in long-term ambulatory monitoring.

Objectives: To develop a method for automatic detection of blinks in electrooculograms and to evaluate reliability of blink rate as an indicator of wake and sleep in subjects with developmental brain disorders.

Design: Categorization of wake and sleep by blink rate was compared with visual sleep scoring of the polysomnograms.

Setting: Ambulatory polysomnographic recordings at home or in the sleep laboratory.
