I am currently working on preprocessing of EEG signals which recorded from newborn children in a resting-state while they were sleeping. I tried to follow the preprocessing methods in chapter 7 and 8 in your book. I did them in the following order: Common average reference (CAR), second-order butterworth bandpass filters, epoching with 2-second length and normalization. After that, I am planning to do epoch removal and bad channel rejection.
1- Do you think these methods are suitable for our case?
2- Do you think I also need to apply the artefacts removal methods even if the data recording while the infant were sleeping? and if so, can you please suggest any automatic removal methods?
Also, I am facing some difficulties in judging the quality of the signal. So, can you please help me in this matter?
In the following, I upload each snapshot before and after the preprocessing method.
Do you think the signal looking good after each step?
