Brain Gauge FAQ


What do I need to run the Brain Gauge?

You will need a PC/Mac running a supported Operating System (Windows 8+, MacOS 10.10+, Linux) with Google Chrome and the Brain Gauge App installed. You will need one USB port available (unpowered USB hubs are not recommended).

We also recommend using a wired computer mouse for responses (this will give more accurate values for reaction time).

How long does it take to use the Brain Gauge?

Each test takes between 1 and 3 minutes and a typical research battery of tests is between 3 and 7 tests. If you just want to find out how one score has changed since you last tested, you can take that one test only.

What do my scores mean?

The Brain Gauge scores compare your performance on a particular test to that of most healthy people; this is based on formal scientific studies that we’ve done over the past decade. Each test is tied to a particular pathway or brain function that the scores have been correlated to in prior studies.

For example, one of the tests is based on research that demonstrated an inability to perform a certain task when a particular brain region was ‘turned off' using TMS. Further information about scores can be found here.

If I purchase a Brain Gauge, will everyone in my family be able to use it? Can I keep my data separate from everyone else’s?

Each individual's data is identified by a nickname or a unique subject ID. The Brain Gauge App is currently limited to five users. If you have more than 5 members in your family please reach out to us. The Brain Gauge App with ProTools has no limits to the number of subjects.

How much is shipping?

Shipping (anywhere in the U.S.) is included. International shipping is avaliable for an additional charge of $25. Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are the buyer's responsibility. Please check with your country's customs office to determine what these additional costs will be prior to buying.

What is the warranty for a Brain Gauge?

Cortical Metrics warrants that your Brain Gauge shall be free from defects in material or workmanship under normal use for one year beginning from the date of shipping of your original purchase. For troubleshooting or to request a warranty replacement, contact customer support.

What is your refund policy?

The Brain Gauge may be returned for a refund within 30 days from date of shipping less restocking fees of 25%. Return shipping is at the expense and responsibility of the purchaser and will not be refunded. Cortical Metrics must be contacted via email to obtain return authorization, shipping address, and instructions.

Returned product must be in original condition and show no evidence of damage caused by accident or abuse. You must prepay all shipping charges and we recommend that you use a carrier that offers shipment tracking and fully insure your package so that you are completely protected if the shipment is lost or damaged in transit. You are fully responsible for any loss or damage to the Product during return shipping.

Is the Brain Gauge safe? Has it been approved by FDA?

The Brain Gauge delivers a gentle mechanical stimulation to the skin. We have conducted tests on over 6000 individuals and have never had an adverse event. It is as safe as a computer mouse.

The Brain Gauge has not been approved by the FDA. The Brain Gauge is not a medical device and cannot treat, cure, diagnose or prevent any dysfunction or disease. The Brain Gauge is a cutting-edge research tool that we are continuing to upgrade and refine.

What's the difference between the Brain Gauge and Brain Gauge Pro?

The Brain Gauge Pro is a research-grade vibrotactile stimulator intended for use by scientists and clinicians. The Brain Gauge was designed as an affordable alternative that sacrifies some of the complicated calibration mechanics for easy of use and portability. The Brain Gauge was designed specifically around the needs of a home user.

What are ProTools? How does it differ from the Brain Gauge App?

The Brain Gauge App is a free app provided to our Brain Gauge users; it's intended to be used at-home by individuals and families interested in monitoring their personal brain health.

ProTools is provided free of charge to all Brain Gauge Pro users. It is intended to monitor large groups of subjects as those seen in clinical or research environments.

Why/how was the Brain Gauge developed?

We are working with the Office of Naval Research to develop standardized measures of brain health to determine if individuals exposed to a blast can safely return to duty. In addition to that kind of brain health measure, we are also developing the Brain Gauge technology to help clinicians compare the brain health of their patients before and after treatment. Individuals are also using the Brain Gauge for self-evaluation.

Our research has received sponsorship from the Office of Naval Research, the National Institutes of Health, the US Army and the NFL/GE Head Health Challenge.

Who uses the Brain Gauge?

Besides researchers and clinicians, the Brain Gauge is for individuals who are curious about their personal brain health.

If I use the Brain Gauge on a regular basis, can I track how I’ve done?

Absolutely. One of the strengths of the Brain Gauge technology is that you can track your performance over time and compare your scores from one day (or condition) to the next.

What will impact my scores?

Anything that impacts brain function has the potential to impact your test scores. The smallest change that we have documented is a double dose of cough syrup.

Are there ongoing studies that I could participate in?

We will periodically send announcements about studies that Brain Gauge users can participate in to anyone on our mailing list (Sign up here). Most traditional studies take one to two years to recruit subjects and collect data. We envision crowd sourcing studies by recruiting Brain Gauge users to take 2-3 minutes of testing. Unlike formal studies, we anticipate being able to announce results within several weeks of the study’s initiation.

Does this make relative measurements or use objective standards?

The sense of touch is a surprisingly objective input; humans as a whole fit within a pretty tight range of acceptable normal results. We utilize your sense of touch as a method to measure brain function and we’ve spent the better part of a decade developing tests that are as objective as possible. No baseline measurements are needed to see if you are fitting into a healthy, normal range. We do however supply you with historical views of your data, so you can see how you’re improving (or declining) relative to previous performance.

Does the Brain Gauge improve brain function?

The Brain Gauge is a tool capable of monitoring brain function. It gives an objective metric of brain health under 6 different categories: Speed, Focus, Accuracy, Plasticity, Sensitivity, and Connectivity; and an overall metric we call your corticalmetric. It is not specifically designed for a particular disorder, it can measure brain function/dysfunction or improvement/decline in anyone that can answer simple questions. We work with researchers at numerous universities to help them explore how the brain changes as it ages or in diseases like Alzheimers, Parkinsons, Autism, PTSD, etc. As far as improving brain performance, the Brain Gauge is mostly designed as a brain health measurement. It would give you clear and consistent measures of either decline or improvement, but we have not dedicated specific time to develop tasks that improve brain health. Some scientists believe that simple discrimination tasks (which the Brain Gauge delivers as part of it’s testing) can improve overall brain performance, as the test requires focused concentration.

Are there any publications that use the Brain Gauge?

There are quite a few publications based on the same technology that the Brain Gauge uses (most of these studies used the Brain Gauge Pro). We’ve been involved in many areas of research over the past decade and continue to expand at a rapid rate in the areas of:

Additionally, we have been involved in a number of basic science studies. All of these publications can be found here
