Blink Artifact Removing

Discussions

Hi all

my question is about blink artifact removing using SSP.
After finding the blinks by detect eye blink and remove using SSP, unfortunately, It seems the blinks didn't remove.
because after the Time-Frequency analysis when I use Time series plot I can see some peaks that related to the blinks and I'm afraid this contamination effect on my results.
I've tried to do blink removing twice but the problem didn't solve.
Would you please let me know how can I remove blinks better than now. I know we can't remove blink completely.

Hi Hamed,

For EEG cleaning, we do not recommend using SSP. Please follow completely this tutorial about EEG processing before trying to analyze your own recordings:

For additional information and other user comments, search this forum with keywords like “EEG ICA”.
