MyND: My Neuro Detector

My Neuro Detector (MyND) is a project that attempts to characterize focus and predict distraction states through scalp EEG.

EEG, EyeTracker, and PsychoPy Marker streams --> XDF

Project Tools

1. PsychoPy
2. Webgazer.js
   
   • A decorated version was used to collect data for this project. See webgazerListener.js
3. OpenBCI Cyton Board V3

Project Versions

• V2.0.1 : Added marker bounds for calibration period.
• V2.0.0 : Reorganized data analysis pipeline. Updated calibration period strings and meme frequency. Short experiment is now similar length as long.
• V1.0.0 : Updated distractor, added memorization aid, and implemented 3 experiment sections. Usable Markers implemented.
• V0.1.2 : Includes Psychopy, Calibration, OpenBCI, and EyeTracker
• V0.1.1 : Includes Psychopy, OpenBCI, and EyeTracker
• V0.1.0 : Includes Psychopy and OpenBCI
• V0.0.1 : NeuroSky data collection, data analysis

Data Analysis

• 00 notebook: Data Check and Filtering -> filtered_cleaned_data
• 01 notebook: Create Data Frame -> df
• 02 notebooks: ERPs, Power Bins, PSD Analysis, FOOOF Analysis, Power By Time
• 03 notebooks: Focus Modeling

Usage

• PsychoPy + OpenBCI Recording
  • python3 recordEEG.py
  • python3 PsychoRun.py
  • Run LabRecorder
  • Select the EEG and Markers stream to record. Edit the save-as file name or change the filename later as desired.
• Eye tracker
  • python3 eyeTrackerSocket_Server.py
  • node app.js
  • go to localhost:3000/index.html
