I am a PhD student at Concordia University enroll in an Individualized program (intersection of cognitive neurosciences and digital arts/electroacoustics) My main PhD focus is on electrophysiological correlates of creativity and pareidolia, as well as how to use this knowledge in Brain-Computer Interfaces (BCI)
But...still waiting for my EEG data!
Instead... Music Imagery Information Retrieval: 10 subjects, 64 EEG Channels for a music imagery task of 12 different pieces w/ different meter, length and tempo

I chose to work with these data so it provides me with a first hands-on experience with EEG data. The produced scripts/notebooks should be reusable for the data I will be collecting in the next few months (hopefully) and for anybody interested in using MNE-Python and complexity measures on electrophysiological data. This project uses open-source EEG data collected on a Music Perception and Imagery task.
- Install MNE-Python
- Load the data into a Jupyter Notebook
- Visualize raw signal
- Independant Component Analysis (ICA)
- Artifact rejection using ICA
- Epoching (channel x condition x trial)
- Compute Power Spectral Density (PSD) averaged by condition
- Complexity measures by channel/song/condition/participant
- Topomaps of complexity measures
- Steady-state-evoked-potential (SS-EP) for each song averaged across subject
- Beat per minute (BPM) for each song
- Compare perceived vs. imagined conditions for each frequency band
- Compare PSD topomap between clustered regions
- Compare complexity measures topomap between clustered regions
- Compare complexity measures for each conditions with complexity measures of stimuli (e.g. correlations of stimuli fractality with brain signal fractality)
- Compare SS-EP for binary vs. ternary songs for each conditions

Commented Jupyter Notebook..

For preprocessing and epoching of data
-
For computation of complexity measures, PSD and related topomaps
