How Do I Analyze My Graphs?

[devpatel17]

Hey!

I am very new to the Mind Monitor app and the MUSE EEG. I am conducting research with the MUSE EEG and your app, Mind Monitor. I wanted to run a trial test first before I started conducting research on other participants. I did it for a couple of minutes, and graphed in Excel using the Macro and code. I am very confused on how to analyze it.

I researched and found that once the brain is scanned using the EEG, the raw data must be processed. Some programs include EEGLAB and Brainstorm, which are very complicated. I saw that Excel graphs, so I took that route instead. Is the graph processed data or is it still considered raw data? If it is raw, how should I process the data?

This is the graph that I got from a couple of minutes:

Could you help me analyze this?

Other Questions:
1. What do each of the waves mean in general?
2. What do rising waves mean?
3. What do sinking waves mean?
4. Which brain waves do I look at for stress levels?
5. Which brain waves do I look at for cravings (urge) levels?
6. Which brain waves do I look at for calm state?

#1 - https://choosemuse.com/blog/a-deep-dive ... plained-2/
#2,3 - Higher/Lower power spectral density.
#4,5 - I'm not sure.
#6 - High relative Alpha - If you want a deep dive in this theory, check out the research paper "My Virtual Dream: Collective Neurofeedback in an Immersive Art Environment" by Natasha Kovacevic, Petra Ritter, William Tays, Sylvain Moreno, Anthony Randal McIntosh: http://journals.plos.org/plosone/articl ... ne.0130129

The brainwaves are the processed result (FFT) of the RAW EEG data.

I am a researcher and using MUSE as a tool for my Perception research. Can I use the data that we get in Mindmonitor Website and use it as a data for the research? For eg:, as seen in the image below, the Absolute brainwaves ar shown for a period of 1 min, which also shows GoodFit, BadFit and Jawclench. Also in the initial 30-35 seconds, it is showing where exactly Beta is at its peak and where exactly THeta or alpha is having a peak. Can we use this along with other tools for conclusive results? Can some one pls advice. THank you in advance

This recording looks bad. I would check your RAW EEG to see if you have a good connection. High Delta usually means the headband is not fitted correctly and the J, BF markers are also very bad.

Greetings,

A stupid question, so I do apologise in advance. Why are the values displayed in dB instead of Hz?

Looking forward to your feedback. Cheers, Josh

[James]

The frequency ranges (Hz) are what define which wave is which. The power of the wave (Bels/dB) is how strong each wave is.
