Your brain is constantly generating electrical signals when you’re thinking, sleeping or even relaxing. These signals can be detected from outside your head, using a technology called Electroencephalogy (EEG).
This is 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.
The Muse headband has 7 finely calibrated sensors – 2 on the forehead, 2 behind the ears and 3 reference sensors – which detect and measure the activity of your brain.
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.
