NeuroFit is structured around development of products by which to make objective, eye-movement based measurements of neural health and function to deliver objective, quantitative metrics of brain health and performance. Among the fastest, most frequent, and most precise voluntary movements made by humans, eye movements offer a useful motor system for exploring the functional performance of neural systems with many assessments - by law enforcement and medical practioners - using grossly-observable oculomotor signs to support quick decisions about neural health and function. Using patent-pending NASA technology, neuroFit is using eye-movement-based oculometrics to provide more specific, objective indicators of neural health and function. The tools being developed can be used across the spectrum of health and disease, from severe impairments in brain injury, disease, and encephalopathy to above-average levels of brain health and to documents visomotor performance in athletes. neuroFit's tools can also be used to identify individuals with above-average visual capabilities, to screen for performance changes, and even to identify the factors that keep athletes from performing at the top of their game, and the factors that keep them there.
