Different aspects of EEG Data are shared in different formats: Raw EEG: continuous EEG recordings alongside behavioural data in BIDS format. Note that raw anaesthesia data can be downloaded here: https://zenodo.org/record/806176#.YURO9dMzZR4 Preprocessed EEG: Epoched EEG recordings alongside behavioural data in .mat (fieldtrip) format. ERPs: Condition-wise average ERPs per participant in .mat (fieldtrip) format. Spectra: Trial-wise power spectral densities per participant in .mat format. Spectral parameterization results: Results of trial-wise spectral parameterization (including goodness of fit) per participant in .mat format.
