Research abstract
DESCRIPTION (provided by applicant): An expert software system is proposed that
will analyze digital polysomnographic data and identify EEG arousals based on
standard criteria (ASDA report: EEG Arousals: Scoring Rules and Examples,
Sleep, 1992).
The algorithm logic closely follows the scoring rules so that information from
intermediate steps leading up to the fmal decision will be made available to
the operator. Phase I research will test three innovative techniques for
marking abrupt changes of EEG frequency corresponding to arousal: techniques
based on spectrogram, "Time Frequency Distribution", and "Instantaneous
frequency". Optimal criteria will be established for discrimination of
polysomnogram sections with and without arousal. A database of sixteen manually
scored full night sleep records will be established with at least 1200 arousal
events. Six records will be used as training set for algorithm development and
optimization, and ten records as an independent test set for the assessment of
algorithm performance.
An effective software tool will be developed by this project for the sleep lab
to assess sleep fragmentation.
