In reading EEGs, one should recognize artifacts which obscure the EEG and may confuse the interpreting physician. Artifacts are signals recorded by EEG but not generated by brain. Some artifact may mimic true epileptiform abnormalities or seizures. Awareness of logical topographic field of distribution...

已知生理因素将伪迹引入EEG的数据记录中。这些包括但不限于: Cardiac signal (Electrocardiogram, ECG or EKG) 心脏信号(心电图、ECG或EKG) Artifacts caused by muscle contraction (Electromyogram, EMG) 肌肉收缩引起的伪影(肌电图,EMG) Ocular signal caused by eyeball movement (Electrooculogram, EOG) 眼球运动...
To avoid the reduction in temporal precision of events that comes with resampling aRawobject, and also avoid the edge artifacts that come with filtering anEpochsorEvokedobject, the best practice is to: low-pass filter theRawdata at or below 1/3 of the desired sample rate, then decimate(抽1...
