Abstract: Highlights•Insufficient and excessive preprocessing synthesized with quasi-stationary assumption.•PaLOSi proposed as a novel quality metric for objective large scale EEG preprocessing.•Postprocessing deviations of spectral and spatial aspects well-associated with PaLOSi.•PaLOSi validated on large real EEG datasets and [0.3, 0.6] recommended as valid range.
