The Brain Gauge is a tool used to measure brain function. This laboratory-grade research tool has merged state-of-the-art technology with a wealth of neuroscience research. The Brain Gauge is a neurosensory assessment tool that tests brain functions through the sense of touch in the fingers. The test is easy to comprehend; however, answering the queries is quite difficult with diminished brain functioning. The Brain Gauge measures various points of interest in brain functioning. This includes speed, accuracy, plasticity, connectivity, time perception, focus, fatigue, and sequencing. These come together to result in a composite score, or cortical metric.
