EOG-Based Recording and Automated Detection of Sleep Rapid Eye Movements: A Critical Review, and Some Recommendations.

This paper presents a critical discussion of methods used for the recording and the automated detection of sleep rapid eye movements (REMs) via electro-oculographic (EOG) methodologies. Specifically, the paper elaborates on: 1) various FOG montages for sleep eye movement recording, 2) AC vs. DC coupling for EOG signal amplification, 3) artifact presence and elimination thereof via filtering of the EOG signal, and 4) available EOG-based automated methods for REM detection. Recommendations for the development of an "optimum" automatic sleep REM detection system based on EOG recordings are presented as well. [ABSTRACT FROM AUTHOR]
