Muse detects a full range of brainwave activity. Brainwaves are typically broken up into five bands and the Muse headband is capable of detecting all five bands. The five bands are:
- Delta waves which are most present during deep sleep.
- Theta waves which are associated with drowsiness, light sleep, and visualization.
- Alpha waves which occur during wakeful relaxation.
- Beta waves which occur when alert, actively thinking or problem-solving.
- Gamma waves which occur when involved in higher mental activity and consolidation of information.
In creating the Muse app, we started from these brainwaves and then spent years doing intensive research on higher-order combinations of primary, secondary and tertiary characteristics of raw EEG data and how they interact with focused-attention meditation.
Your brain is constantly generating electrical signals when you’re thinking, sleeping or even relaxing. These signals can be detected from outside your head, via sensors.
Muse uses the same brain sensing technology that doctors and scientists have employed for more than a century to detect your brain signals, similar to how a heart monitor measures your pulse. Muse then sends that feedback to your smartphone or tablet using Bluetooth connectivity.
The headband has 7 finely calibrated sensors – 2 on the forehead, 2 behind the ears plus 3 reference sensors – which detect and measure the activity of your brain.
