nFit

nFit is a NASA-developed biomarker of brain health (U.S. Patent 10,420,465, U.S. Trademark 87299329). It uses a multi-dimensional vector of metrics from our simple 5-minute task to quantify the signal-to-noise ratio of injury, disease, or supranormal visual tracking. Our biomarker can monitor subtle physiological changes over time, detect acute impairment, quantify the effectiveness of therapy, and can also be used for biofeedback.
