一种不太常见的心脏伪影是心弹伪影,其中脑电图电极放置在动脉上方,动脉的每次搏动都会在脑电图上作为运动伪影被拾取。 4)电和电极伪影(Electrical&Electrode artifacts): 电伪影最常见的原因是通过电线传输的 60 Hz (如美国)电活动(某些地区为 50 Hz,如欧洲等)的干扰。当然,电伪影是一种非常快速、非常单调的活...
The best results of the spatial filtration method are obtained for eye movement artifacts. The procedure starts with defining an EEG epoch. This epoch will be used as a template for constructing the filters for artifacts. After defining the EEG epoch the procedure is initiated by pressing the ...
the MNE-Python toolbox then auto-identified components that were extremely correlated with eye-related activities in electrooculography (i.e., EOG from HEO and VEO channels). After removing these eye movement artifacts, we reconstructed the eye-unrelated EEG signals with the remaining independent com...
The VEOG was used in the detection of blink artifacts, and the HEOG was used in the detection of horizontal eye movement artifacts. Electrophysiological signals were digitized at 512 Hz. Data analysis Behavior Error scores on the memory test were calculated as the difference between the ...
Moreover, the frequencies of EEG artifacts (such as blink artifacts, eye movement artifacts, electrocardio artifacts, etc., except for power–frequency artifacts and myoelectricity artifacts) mainly coincide with the delta frequency band. The removal of the artifacts is highly subjective, and the ...
In REM sleep, the EEG consists of diffusely distributed, moderate to low-amplitude mixed frequencies with rapid eye movement artifacts seen in the anterolateral head regions. The features of NREM sleep are absent during REM sleep (i.e., vertex sharp waves, sleep spindles, and K complexes). ...
the sparse generalized eye artifact subspace subtraction (SGEYESUB) algorithm presented in [1]. 4 other eye artifact correction algorithms presented in [2-5]. After the algorithm parameters are fitted to calibration data, eye movement and blink-related eye artifacts can be corrected offline and on...

(e.g., coughing, sneezing, verbal movement, and questions), enabling us to check and exclude disrupted sections of the recording whenever necessary. After visual inspection, we excluded any samples that were overall very unstable and noisy. Most of the eye movement artifacts have slow ...
