This page contains the data and analysis of a brain wave recording session I did using a Muse EEG Headband.
Session Characteristics
- 30/09/2023, 22:18
- I had slept a long nap and was feeling very calm and relaxed.
- I was lying down in bed with my eyes open.
- This session was immediately followed by Session 2, which was similar in everything except it was done with closed eyes. For a more complete comparison between the two sessions, visit the Session 2 page.
All Sensors
- Given that I had my eyes open, the large oscillations led byDeltaare most likely from blinking. These are signal artifacts and shouldn’t be taken into consideration.

- Zooming into a more stable portion (the green rectangles), where no oscillations occur, we can see thatAlphawas the most prominent frequency range during the session.
- This relationship between frequencies looks more like what’s expected from a relaxed state (withAlpha,typically representing a more idling state, leading in dominance, while the fasterBetaandGammafrequencies having the lowest dominance).
Individual Sensors
- Looking into each individual sensor, the same frequency relationship can be found in the Back sensors (TP10 and TP9).
- In the Front sensors (AF7, AF8),Deltadominates instead. This might be an overrepresentation caused by blinking.
- Below is the smoothed-out data from each of the sensors:

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