Electroencephalography, or EEG, is a non-invasive technique that records the brain's electrical activity through sensors placed against the surface of the head.
As it works, the brain produces extremely faint electrical changes, generated by the coordinated activity of nerve cells. The wearable device picks these signals up passively throughout the session, sending nothing back and interfering with nothing.
The signals are then processed to follow several frequency bands, among them alpha, beta, theta, delta and gamma. Forma Mentis uses the changes it finds to derive measures such as focus, calm, energy, complexity and balance, which become part of how the image is generated.
The data is never used to read thoughts, memories or particular emotions, and it offers no medical or diagnostic assessment. It is the trace of brain activity recorded in that precise moment, translated into the visual language of Forma Mentis.
We do not read what you think: we follow how your brain activity changes, and turn that into creative material.
