METHODOLOGICAL INFORMATION 1. Description of methods used for collection/generation of data: The auditory stimuli were amplitude-modulated tones with a carrier frequency (fc) of 500 Hz and modulation frequencies (fm) of 20.48 Hz, 40.96 Hz, or 81.92 Hz. The experiment was programmed in python: https://www.python.orgÖppnas i en ny tabb and used extra functions from here: https://github.com/stamnosslin/mnÖppnas i en ny tabb The EEG data were recorded with an Active Two BioSemi system (BioSemi, Amsterdam, Netherlands; www.biosemi.comÖppnas i en ny tabb) and saved in .bdf format. For more information, see linked publication. 2. Methods for processing the data: We conducted frequency analyses and computed event-related potentials. See linked publication 3.

People involved with sample collection, processing, analysis and/or submission: - Data collection: Malina Szychowska with assistance from Jenny Arctaedius. - Data processing, analysis, and submission: Malina Szychowska and Stefan Wiens DATA-SPECIFIC INFORMATION: All relevant information can be found in the MNE-Python and R scripts (in EEG_scripts and analysis_scripts folders) that process the raw data. For example, we added notes to explain what different variables mean.
