Combine EEG/MRI/Behavioral data-sets to learn more about Music/Auditory system

Summary

I'm currently a PhD student of the IPN at McGill University.

In this project I aim to combine data from different modalities (fMRI, EEG, and behavioral) to understand more about sound and music processing.

My main focus in this project was to try to reproduce some of the results from a published paper starting form raw data.

The overall goal of the current project is to be able to organize, pre-process and do some basic analyses form a fMRI study.

Project definition

Background

In my current PhD project one of the end results should be a open multimodal behavioural and neuroimaging dataset characterizing healthy human auditory processing. It aims to allow researchers address individual differences in auditory cognitive skills across brain functions and structures, and it will serve as a baseline for comparison with clinical populations. To achieve that, our core objectives are to create a standardized framework with which to administer a battery of curated tasks. After acquiring the data from 70 young adults and we intend to share our framework, analysis pipelines, stimuli with linked descriptors, and metadata with the community through open data repositories. The dataset contains cognitive and psychophysical tasks, as well as questionnaires designed to assess musical abilities, speech, and general auditory perception. It also includes EEG and fMRI recorded during resting state, as well as naturalistic listening to musical stimuli and speech.

During this BrainHanks School project I wanted to understand what are the needs as a researcher to easily make use of public available data and learn the basics of pre-processing raw fMRI data.

Learning Goals

I have good experience analyzing highly process data... but how you get there?

(but it is a 2 and a half week project...)

Estimating Time

Tools

The project will rely on the following technologies:

Data

The first step was to search for candidates open datasets. I prioritized music/auditory related, as it is closer to my PhD project.

Next there is a list of interesting datasets I found, which I choose 2 to work during this course:

Chosen

Other Options

Interesting but not related

NOT Accessible

I also find some very interesting datsets that I was not able to access directly and in the period of 3 weeks I was still waiting for them.

I was a little frustrated with the process, making me realize how important is real Open Data.

Deliverables

At the end of this project, we have:

Project plan / Objectives

Installation instructions

  1. Clone the repo to your computer:

    git clone https://github.com/brainhack-school2020/BHS-AuditoryMultimodal.git

  2. Install fMRI prep using this instructions

  3. Download and preprocess the data using these scripts (you can grab a coffee or two... these may take a while).

  4. Create a virtual-env python3 -m venv bhs-auditory

  5. Install requirements pip install -r requirements.txt

  6. Open the notebook jupyter lab BHS_AuditoryMultimodal-ds000171.ipynb

Conclusion and acknowledgement

After the multiple problems I found trying to process the data, reproduce the analyses, and limitations imposed by the missing of information form the dataset I am more aware of what I will need to do to efficiency share my data/analyses in the near future.

Don't be that researcher...
