Traumatic Brain Injury (TBI) has been featured prominently in the news for the past few years. Public awareness of brain injuries has led to a growing number of people asking us about treatments for TBI, and in particular, mTBI. For those of you unfamiliar with the nomenclature, mTBI stands for “mild” TBI and this is often used synonymously with concussion. Moderate and severe TBI are much worse conditions of brain trauma, and the dividing line between mild and moderate is (usually) how long someone was in a coma post-traumatic injury

Reaction time is one of the most frequently collected and depended upon metrics for cognitive assessment – but most methods are extremely inaccurate. The Brain Gauge is the world’s most accurate commercially available device that can deliver the reaction time test.

It seems like there is a constant and steady improvement in technology and computing power. The cell phones that we carry now have exponentially more computational power than computers that we (I speak for the people in my generation) were programming in the late 1970s and early 1980s. However,

Exercise can give your brain an immediate boost – we conducted a simple study and report results.
Reaction time (RT) is one of the most common ways to measure brain activity. Simple reaction time - the time elapsed between a stimulus and corresponding response - has been used to assess cognitive function in both healthy and impaired individuals. Reaction time variability (RTvar) - a measure of the standard deviation of reaction time scores - can be used to quantify attention span, and tends to be higher in people with ADHD and
