The NUROCHEK™ system is a world-first portable brain assessment device set to revolutionize the assessment of brain health. The Nurochek system uses Visual Evoked Potential (VEP) to measure aspects of the brain’s electrical activity using EEG. This form of testing is usually confined to ophthalmology clinics and hospitals. In this design, the Visual Evoked Potential (VEP) technology is integrated into a portable device for on-demand scanning and immediate analysis. One test takes just two minutes, thus improving the efficiency of testing in different environments including the sports field and in an emergency services context.
