The Safest and Most Effective Nootropic

How short bursts of exercise can boost cognition
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 other attention disorders.

We conducted a study which


Brain Gauge Concussion Scoring

The results are in! With over 2000 subjects in the concussion study, we have some pretty solid results for you to compare with.
**The Fatigue metric is computed and correlates well with standardized clinical assessments of fatigue that rely on questionnaires.

*TOJ and DD are dependent on location of trauma. TOJ is more likely to deviate from the norm with front of head injury and DD is more likely to deviate with back of head injury. In other words, insult to the front of the head may result in a


CAP Corporation has partnered with Cortical Metrics to integrate their award-winning Brain Gauge Technology


CAP (Concussion Active Prevention) Corporation and Cortical Metrics announced today that they have signed a long-term strategic alliance to realize market opportunities that will utilize their joint assets.

Cortical Metrics has been dedicated to developing objective, quantitative, reliable and efficient assessments of brain performance by merging state-of-the-art engineering and neuroscience. Originally spun out of the University of North Carolina following decades of neuroscientific research, Cortical Metrics works with a large consortium of researchers specializing in neurological disorders.

The integration of Brain Gauge into the CAP program allows CAP to cross-communicate

Concussion Study Update

Summary of previous report: Our brain health assessment system is composed of a test device (the Brain Gauge; above) and a number of tests that task different mechanisms of information processing (e.g., lateral inhibition, adaptation, feed-forward inhibition, neuron-glial interactions). The results of these tests are then used to generate an overall performance score (or cortical metric). Sports concussion studies using this technology and protocols have established efficacy for detecting mTBI and tracking its recovery, demonstrating a 99% confidence level (p<0.01) for differentiating individuals

Large Changes to ProTools coming this week

Major changes to those of you using our ProTools software will be rolling out this week. The software you know and love is largely staying the same, but we have tweaked the way data sessions are viewed with a more efficient and intuitive data timeline. We are dedicated to providing updates to improve our system, and we think you'll find that this new version of ProTools is much faster and more intuitive.



Each data session is now a point
