EEG Dataset on the Effects of Interoception in Music Listening and Recall

EEG Dataset on the Effects of Interoception in Music Listening and Recall

This repository contains EEG data (in .fif format) and corresponding musical stimuli (in .wav format) used in an experiment studying brain responses during music recall. The dataset is intended to enable others to replicate or extend the analyses presented in our manuscript.

Contents

EEG Data

Format: MNE-Python .fif 

Participants: 22 in total (mk1p–mk17p & mk18–mk22)

Each participant’s file includes multiple epochs (20 s each) that cover baseline, cue, music presentation, and a short post-music period.

Metadata (stimulus name, presentation order, and familiarity rating) is embedded in each .fif file.

Musical Stimuli

Format: .wav (44.1 kHz sampling rate)

Each file corresponds to a single music excerpt of 12.8 s, which aligns with the music portion in the EEG data.

Additional JSON Metadata

Format: .json 

Contents:

Per-participant keys (e.g., "mk1p", "mk2p", etc.)

Gender, Age, IAcc Score (interoceptive accuracy), and a metadata field containing epoch-level information (familiarity, trial number, etc.)

The structure is designed to complement the .fif files, providing additional context about each participant (e.g., demographic info, interoceptive accuracy scores) not contained in the EEG files.

Experiment and Data Description

EEG Recording

Original Sampling Rate: 2048 Hz

Preprocessing:

Notch filter at 50 Hz

FIR bandpass filter (0.5–40 Hz)

Downsample to 256 Hz

Re-reference to the average of M1 and M2

ICA removal of ocular components (Pearson correlation > 0.9 with EOG signals)

Epoch extraction (20 s total per epoch):

4 s baseline

1 s standby

12.8 s music

2.2 s post-music standby

Musical Stimuli

Each .wav file is 12.8 s long and sampled at 44.1 kHz.

The music onset in the EEG data begins at approximately 5 s into each epoch.
