   Can EEG channels be predicted as bad?

   • Precisely, channels are predicted as bad if the computed probability falls more than three standard deviations from the mean. Since developmental EEG presents severe contamination of artifacts compared to adult EEG, the authors performed the computations twice for each file. 3. Description of EEG Datasets 3.1.

   How do you detect a bad channel in EEG?

   • Within the EEG literature, the widely used bad channel detection methods employ measures such as Kurtosis [ 22 ], Pearson Correlation [ 23 ], Channel Variance, Hurst Exponent [ 24 ], and Normalized Power Amplitude [ 25 ].

   Why do we need to remove bad channels from EEG data?

   • The detection and removal of bad channels (i.e., with poor signal-to-noise ratio) is a crucial initial step. EEG data acquired from different populations require different cleaning strategies due to the inherent differences in the data quality, the artifacts’ nature, and the employed experimental paradigm.

   Is a bad EEG channel A gradiometer?

   • The bad EEG channel is not so obvious, but the bad gradiometer is easy to see. Remember, marking bad channels should be done as early as possible in the analysis pipeline.

   What is bad channel exclusion / interpolation in EEG/MEG preprocessing?

   • Bad channel exclusion or interpolation is an important step in EEG/MEG preprocessing. MNE-Python provides tools for marking and interpolating bad channels; the list of which channels are marked as “bad” is propagated automatically through later stages of processing.

   If you know which channels are bad, you may reject them using the function pop_select.m called by selecting the Edit → Select data mneu item. In the example below, we remove channel 3, 45, 55, 73, 74, and 75 identified in the previous sections. Press Ok to remove the channels.

   Apr 10, 2022 · The goal of this chapter is to teach you how visually inspect EEG data and how to identify bad channels and common artifacts. You’ll also learn how to replace bad channels with interpolated data. The subsequent chapters will cover artifact rejection and artifact correction.

   Apr 25, 2024 · Interpolating bad channels. We will now explore two different ways of dealing with noisy channels. One is to interpolate entire channels. The other way is to interpolate only segments that contain artifacts. We repair channels by interpolation, or more precisely by replacing the bad channel with the average of their neighbouring channels.
