EEG data can be recorded and analyzed in a lot of different ways, and not only the processing steps themselves but also their sequence matters (One example of the significance of pre-processing steps’ sequence is described in Bigdely-Shamlo et al., 2015). All signal processing techniques alter the data to some … Visa mer EEG experiments require careful preparation. You need to prepare the participants, spend some time on setting up the equipment and run initial tests. You certainly do not want your EEG experiment to fail mid … Visa mer Wise words of Prof. Steve Luck(UC Irvine) that you should keep in mind whenever you record and pre-process EEG data in order to extract metrics of interest.

WebbThe EEG signal, a recording of the brain activity using multiple electrodes placed on the scalp, can be hardly contaminated by a lot of noises called artifacts. The artifacts are generated by the action of the skeletal muscles such as: eye movements, jaw clenching, etc. Indeed, the signals recorded are mixture of phenomenon from multiple generators. …
