Images of My Brainwaves and Progress Graphs Over Time.
The observations in this section are all based on my personal experience.
I’m not saying ‘THIS IS HOW IT IS FOR EVERYONE’. I am saying this is my experience. This is my truth. And these are MY BELIEFS – at this point in time.
I hope you find the frequency game as fascinating as I do.
What I use to measure my brainwaves
I use the Muse 2 to record my brainwaves, and I extract the raw data using Mind Monitor. The Muse 2 only has 4 electrodes – it’s a baby, compared to more sophisticated (and expensive) EEGs. I’m aware that some researchers might snigger at the concept of portable EEGs – I get it. But it’s all that many researchers like myself can access. It’s far from perfect, but in saying that, it’s accurate enough that NASA, MIT, Harvard, The Mayo Clinic and many other highly-regarded research institutions use Muse.
Dr Olav Krigolsen, a professor and researcher at The University of Victoria, has written a research paper which compares Muse to a gold standard EEG that costs over $100,000, and the results were comparatively the same (though far less detailed obviously). You can check out an interview with Dr Krigolsen explaining his findings here.
I dream of the day I can get my hands on some serious EEG equipment along with the expertise of someone who can interpret it for me. But for now? I use what is available to me.
In my nerd-zone.
EEGs of My Brainwaves While Mindful Drawing
TP9 - Temporal Left Side (above my ear)
The first image is an example of low gamma (the orange line), the second image is of high gamma.
TP10 - Temporal Right Side (above my ear)
The first image is of low gamma, and the second image is high gamma.
AF7 - Left Frontal Lobe
First image is low gamma, second image is high.
AF8 - Right Frontal Lobe
I actually can’t pull up high gamma in this part of my brain very often…(I never used to be able to budge it at all). I talk about this more a little further down the page.

Progress Graphs of my Mindful Drawing Sessions -
from May 2020
Raising frequency is often not straightforward. Every session I record is not simply higher frequency than the last. Out of say, 10 sessions – 6 or 7 will result in high gamma – even if you’re doing all the ‘right’ things and it feels high. The others won’t –with no clear reason why.
Factors that can raise gamma brainwaves one day, repeated the next day may not. There are many factors I cannot see, or control (like EMF interference, hormonal cycles, even planetary influences perhaps), and there are things that are beyond my current states of awareness.
When you zoom in and scrutinize every session, looking for repeated examples of cause and effect sometimes you won’t find it (and it can be a little frustrating!). But zoom out. NOW view your progress. Now you can see you’re definitely doing it. It’s just not always straightforward, predictable or linear.
