I have a dataset that I imported to Brainstorm a while ago. This dataset was already preprocessed: filtering, ICA, and thresholded (removing the most noisy epochs).
Now, I have realised that I have a lot of ocular artifacts in my recordings, and I would like to pose some issues before assessing this problem:
- Is it metodologically correct to remove eye blinks using SSP after the preprocessing that I have mentioned? (https://neuroimage.usc.edu/brainstorm/Tutorials/ArtifactsSsp#SSP:_Eye_blinks)
- Is there any way to add, for each subject in the database, the EOG channels? Because I discarded the EOG channels before importing them... (my fault )
Thank you very much in advance!
