Rapid Eye
Movements (REMs) of REM sleep can produce specific artifacts in EEG recordings.
1. Nature of REM Artifacts:
o REM artifacts are
associated with the rapid eye movements that occur during REM sleep.
o These artifacts
have a waveform that differs from lateral gaze artifacts during wakefulness due
to the specific movement features of REMs.
2. Characteristics:
o REM artifacts
appear as waves with an asymmetrically quicker rise than fall, similar to the
REM eye movement pattern.
o The location of
REM artifacts is typically the same as other artifacts produced by lateral
gaze, with specific electrode involvement.
3. Differentiation:
o Specific movement
features of REMs, such as the waveform characteristics, help differentiate REM
artifacts from other ocular artifacts and EEG patterns.
o Understanding the
unique features of REM artifacts is crucial for accurate interpretation and
differentiation from pathological brain activity or other types of artifacts in
EEG recordings.
Recognizing the
distinct characteristics of REM artifacts and their association with REM sleep
can aid in accurate EEG interpretation and the identification of normal
physiological patterns during sleep stages.
