Links to the hardware and software are provided under methodological information.<br><br><br>AAN3_experiment_scripts.zip: contains the Python files to run the experiment<br><br><br>AAN3_rawdata_EEG.zip: contains raw EEG data files for each subject in .bdf format (generated by Biosemi)<br><br><br>AAN3_rawdata_log.zip: contains log files of the EEG session (generated by Python)<br><br><br>AAN3_EEG_scripts.zip: Python-MNE scripts to process and to analyze the EEG data<br><br><br>AAN3_EEG_source_localization_scripts.zip: Python-MNE files needed for source localization. The template MRI is provided in this zip. The files are obtained from the MNE tutorial (https://mne.tools/stable/auto_tutorials/source-modeling/plot_eeg_no_mri.html?highlight=template). Note that the stc folder is empty. The source time course files are not provided because of their large size. They can quickly be generated from the analysis script. They are needed for the source localization.<br><br><br>AAN3_analysis_scripts.zip: R scripts to analyze the data. The main file is performance_correction.html. It contains the results of the main analyses.<br><br><br>AAN3_results.zip: contains summary data files, figures, and tables that are created by Python-MNE and R.<br><br><br>METHODOLOGICAL INFORMATION<br><br><br>1. Description of methods used for collection/generation of data:<br>The auditory stimuli were two 100-ms tones (f = 900 Hz and 1400 Hz, 5 ms fade-in and fade-out).<br>The experiment was programmed in Python: https://www.python.org/ and used extra functions from here: https://github.com/stamnosslin/mn <br>The EEG data were recorded with an Active Two BioSemi system (BioSemi, Amsterdam, Netherlands; www.biosemi.com) and saved in .bdf format.<br>For more information, see linked publication.<br><br><br>2. Methods for processing the data:<br>We computed event-related potentials and source localization. See linked publication<br><br><br>3.
