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:
1. Delta waves which are most present during deep sleep.
2. Theta waves which are associated with drowsiness, light sleep, and visualization.
3. Alpha waves which occur during wakeful relaxation.
4. Beta waves which occur when alert, actively thinking or problem-solving.
5. Gamma waves which occur when involved in higher mental activity and consolidation of information.
