MATLAB Toolboxes for Reference Electrode Standardization Technique (REST) of Scalp EEG

Abstract: Reference electrode standardization technique (REST) has been increasingly acknowledged and applied as a re-reference technique to transform an actual multi-channels recordings to approximately zero reference ones in electroencephalography/event-related potentials (EEG/ERPs) community around the world in recent years. However, a more easy-to-use toolbox for re-referencing scalp EEG data to zero reference is still lacking. Here, we have therefore developed two open-source MATLAB toolboxes for REST of scalp EEG.… Show more

“…Unfortunately all such references are doomed to fail since there is no point on the scalp or body surface where the potential is actually zero or a constant [ 29 ].” An alternative approach is the reference electrode standardization technique (REST). REST standardizes a reference point at infinity in recovering temporal information in EEG [ 30 , 31 ]. As more and more studies show the choice of reference points impacts EEG spectral and connectivity analysis [ 32 35 ], the generalizability of our results is limited.…”

“…The EEG was digitized at 500 Hz using BrainAmp amplifiers and BrainVision recorder software (BrainProducts GmbH, Munich, Germany) with an initial reference at FCz. The data was then re-referenced offline using the Reference Electrode Standardization Technique to standardize the reference of scalp EEG recordings to a point at infinity that, being far from all possible neural sources, acts like a neutral virtual reference (Yao, 2001 ; Dong et al, 2017 ). To avoid corrupting the raw data, we manually extracted segments of artifact-free EEG data by visually identifying and then removing vertical eye movements, blinks, muscle activity, and other artifact sources.…”

“…Then, we determined an epoch of the EEG data analysis corresponding to each trial, containing EEG signals 1 s before the onset of the target phase to 3 s after the onset of the item phase; a single epoch spanned 7 s, consisting of 1 s of fixation, 3 s of the target phase and 3 s of the item phase. Also, we eliminated the noisy channels (FP1, FP2) and applied the standardized REST methods to avoid a potential issue of lateralized referencing (Yao, 2001 ; Yao et al, 2005 ; Dong et al, 2017 ). Only 96.06% trials were used after outlier elimination (<120 μV).…”
