What does the Brain Gauge measure?

The Brain Gauge is a cognitive assessment tool that can be used to measure brain function. During each test, the Brain Gauge will deliver a stimulus to your fingertips, and you'll be asked a variety of questions about your sensory perceptions. 

Different tests correspond to different components of cognitive function. For example, the Simple Reaction Time test is used to calculate your Speed score - a reflection of your brain's ability to react to changes in your environment.

For more information on scores, see the Checking your results section of the support page.
