EEG-Notebooks

Democratizing the cognitive neuroscience experiment

EEG-Notebooks is a collection of classic EEG experiments, implemented in Python 3 and Jupyter notebooks. The experimental protocols and analyses are quite generic, but are primarily taylored for low-budget / consumer EEG hardware such as the InteraXon MUSE and OpenBCI Cyton. The goal is to make cognitive neuroscience and neurotechnology more accessible, affordable, and scalable.

Note: eeg-notebooks underwent major changes to the API in v0.2. The old v0.1 is still available if you need it, in this repo.

Overview

Conventional lab-based EEG research typically uses research-grade (often high-density) EEG devices, dedicated stimulus delivery software and hardware, and dedicated technicians responsible for operating this equipment. The price tag for these items can easily extend into hundreds of thousands of dollars, which naturally places major limits on their acquisition and usage.

In recent years, however, developments in hardware and software technologies are making it possible for many classic EEG cognitive neuroscience experiments to be conducted using a standard laptop/personal computer and a relatively cheap consumer-grade EEG device, with a combined minimum cost of less than 1000 dollars. This opens dramatic new possibilities for neurotechnology and cognitive neuroscience education (at both University and High School levels), as well as more ambitious and larger-scale research and clinical applications using large numbers of devices, and/or in more naturalistic (i.e. out-of-the-lab) settings. We like to think of this as contributing to the democratization of the cognitive neuroscience experiment.

The core aim of the EEG-Notebooks project is to provide the critical 'glue' that pulls together the various enabling technologies necessary for running these experiments and analyzing the data. This includes functionality for

• streaming data from various relatively new wireless consumer-grade EEG devices
• visual and auditory stimulus presentation, concurrent with and time-locked to the EEG recordings
• a growing library of well-documented, ready-to-use, and ready-to-modify experiments
• signal processing, statistical, and machine learning data analysis functionalities

Documentation

The current version of eeg-notebooks is the 0.2.X series. The code-base and API are under major development and subject to change.

Check the changelog for notes on changes from previous versions.

Installation instructions, steps for getting started, common troubleshooting solutions and more can be found in the documentation for eeg-notebooks, available on the documentation site.

Acknowledgments

EEG-Notebooks was created by the NeurotechX hacker/developer/neuroscience community. The ininitial idea and majority of the groundwork was due to Alexandre Barachant - including the muse-lsl library, which is core dependency. Lead developer on the project is now John Griffiths .

Key contributors include: Alexandre Barachant, Hubert Banville, Dano Morrison, Ben Shapiro, John Griffiths, Amanda Easson, Kyle Mathewson, Jadin Tredup, Erik Bjäreholt.

Thanks also to Andrey Parfenov for the excellent brainflow library, which has allowed us to dramatically expand the range of supporte devices; as well as the developers of PsychoPy and MNE, which together make up the central scaffolding of eeg-notebooks.
