EEG preprocessing/processing using MNE-Python

Background

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.

Preprocessing

• [x] Install MNE-Python
• [x] Load the data into a Jupyter Notebook
• [x] Visualize raw signal
• [x] Independant Component Analysis (ICA)
• [x] Artifact rejection using ICA
• [x] Epoching (channel x condition x trial)

Processing/Feature extraction

• [x] 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

Analyses

• [ ] 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
• [ ]

Deliverables

Commented Jupyter Notebook..

• [ ] For preprocessing and epoching of data

• [ ] For computation of complexity measures, PSD and related topomaps

• [ ] Draft of a paper if any promising results!

• [ ] Requirements.txt

• [ ] Wrap-up on Binder
