Brain waves while listening to Beta Audiovisual Entrainment (NEX30)

This page contains the data and analysis of a brain wave recording session I did using a Muse EEG Headband.

Session Characteristics

• 19/11/2023, 16:30
• During this session, I was testing aBetaAudiovisual Brainwave Entrainment track I created.
• I was listening to the track with my eyes open.

Key Insights

• + 26%Betadominance
• + 128%Gammadominance
• Beta+Gammabrain wave phase coherence

All Sensors

• As usual,Alphadominates, but not as much as when my eyes are closed. Therefore,Alphaappears less separated from the frequencies below.
• Similar to Session 24, there is a clear gradual increase ofGammaenergy over time.
• Betadominance is down in fourth place (instead of second place). Based on my experience with otherBetatracks, I have higher expectations in this regard. So, should I classify this track as a failure? Let’s inspect a few more things first.

Right-Back Sensor (TP10)

• Looking at the Right-Back quadrant, some signs of entrainment can be found ✅
• First, theGammafrequency range oscillates in a predictable sinusoidal, orderly pattern, in a way that hasn’t been observed outside any brainwave entrainment session.

• Secondly, BetaandGammaare phase-locked, with their peaks and valleys aligned.

Front Sensors (AF7, AF8, Smoothed Out)

• Looking at the Front-Left (AF7) and Front-Right (AF8) sensors, more interesting data can be found.
• In both places,BetaandGamma show an upward trend while other frequency ranges decrease, are stable, or increase only slightly.
• In the Front-Left (AF7) quadrant,Betaincreased 26% in dominance andGammaincreased 24% in dominance.
• In the Front-Right (AF8) quadrant,Betaincreased 12.5% in dominance andGammaincreased 128% in dominance.
• This, plus the previous section, scores points in favor and restores this track as a properBetaandGammaentrainment tool.

Quadrant Energy Levels (Overview)

Centers of Gravity (Overview)

For reference: the circle with the black circumference marks the central area of the brain. Activity inside it is more central and symmetrical; outside is more asymmetrical.

Centers of Gravity (More Specific)

The section above provides an overview of the centers of gravity for each brainwave frequency. Occasionally, we find that certain centers of gravity develop a trend over time, and that’s always interesting to investigate further with additional graphs. For this session, we have:

• In the right hemisphere specifically, Gamma’scenter of gravity shifted from the back towards the front.
  • Comment: this seems particularly interesting, because frequencies tend to have more energy in the back. I would attribute this the entrainment track. This behavior has been observed in other entrainment tracks as well.
• In the front part of the brain specifically, Gamma’scenter of gravity shifted slightly from the left towards the right.
  • Comment: This behavior has been observed in other entrainment tracks. However I have no specific interpretation or comment about the practical implications of this change.
