Freya posted a comment on a wiki page
Thanks for your reply! it has really cleared things up for me!!!
-
Dear Freya, I believe I provided a fair and balanced assessment what the method can and can not provide. Whether this is "convincing", or in other words good enough for your purpose, is not up to me to decide.
-
Thanks again for your reply! Our neurofeedback training protocol only collected EEG signals from the central zone (Fz/FC1/FC2/FCz/Cz). For this aspect, regression analysis may be more suitable for us. As you said, any method has the potential to increase noise when removing EOG artefacts. If we still use the regression approach, we report (Fig 3 [1]) and (Fig 4, [1]. ) via a pre-experiment , is this convincing enough? I meant to report only how many EOG artifacts were removed from the EEG data, not...

For most pratical purposes, the method described in [1] as good as you can get. Make sure that the EOG channel are close to the eyes so that it does not pick up to much EEG activity. If you want to improve on that, you might try some subspace methods (ICA, PCA, etc.) but you need a large number of electrodes (at least 20, probably more) in order to identify a 3rd spatial EOG component. Concering the 1/f analysis, you should take into account that this might be conflated by other artifact sources,...

Thanks so much for your suggestion – it's really helpful! We're currently using the Brain Products system to collect EEG data, and gathering EOG data through a ground electrode (AFz) and a subocular channel. Our main goal is to analyze aperiodic neural activity through real-time signal processing. However, as you anticipated, in the process of removing the ocular artifacts, we also ended up removing some of the aperiodic neural activity (the 1/f fit gave us negative values, which is unusual). We...

Hello Freya, Concering 1): I'm not using EEGLAB so I can not comment on this. do you mean "rtsBCI" [2] (no rstBCI) which is the Matlab/Simulink-based recording from Reinhard Scherer.? It that case, you might need to add simulink block that multiplies the sampling vector with a suitable, sparse, re-referencing matrix. Concering 2). Technically, you can. The question is about the resulting signal quality. (i), you will capture and reduce only 1 spatial EOG components. (ii), which reference electrode...

Hello, Alois！We are currently engaged in the process of designing a neurofeedback training protocol. We would like to process the 5 channels of the central area online, and we think that it would be better to use linear regression to remove eye movement artefacts. We found your article published in 2007 demonstrated in detail the computational process and advantages of this method (Schlögl et al., 2007) and its use in biosig (Vidaurre et al., 2011). Our questions now are: 1, we added the biosig plugin...
