Scientific Background of Mind Tracker

To get more information on electroencephalography and brain alpha activity, we recommend reading the following articles:

1. Electroencephalogram alpha activity: modern interpretations, O. Bazanova
2. EEG-alpha rhythms and memory processes, W. Klimesch
3. EEG alpha and theta oscillations reflect cognitive and memory performance: a review and analysis, W. Klimesch
4. Alpha-band oscillations, attention, and controlled access to stored information, W. Klimesch

In the Mind Tracker app, users can determine their intrinsic inclination to various activities (based on individual Alpha Wave Frequency, iAF, and individual Alpha Peak Frequency, iAPF). The algorithm for this function is based on the research by Olga Bazanova, moreover, it was developed with her direct participation.
