Abstract

EOG marker for EEG processing: Eye movements during EEG could cause artifacts or in case of sleep are used for scoring of the REM sleep stage. Automatic detection could help with preprocessing and automatic sleep scoring. This project propose analog and digital methodology of eye movement detection. There were construct simple electronic circuit for demonstrating of eye blinking detection. In the future, the analog output can be converted to a binary logic output and save a time-synchronized record of the markers together with the EEG signals. Digital detection is related to eye movements during REM sleep stage. It aims to detect eye movement samples in signal which is measured by polysomnography. Ground truth was set by physicians. We propose eye movements detector based on threshold, amplitude and local maximum detection. Results were described by ROC analysis.EOG marker for EEG processing: Eye movements during EEG could cause artifacts or in case of sleep are used for scoring of the REM sleep stage.
