Combining Mixed Reality Tech With Brain Signals Could Improve Rehabilitative Medicine

A new headset and software platform allows researchers and developers of mixed reality programs the opportunity to incorporate signals from the brain and body into their technology, something that has wide potential for use in rehabilitative medicine.

Virtual and augmented reality has already been used to treat patients with a range of psychiatric disorders including ADHD, PTSD and anxiety, but this tech could help improve how effective it is.

“You can use virtual reality to put people into those environments and throttle how intense the experience is, but if you could know how intense the reaction is that someone is having, you can decide whether to dial it up a little bit, or dial it down a little bit just to make sure that they’re not overwhelmed by the immersion,” says Conor Russomanno, CEO of OpenBCI, a Brooklyn-based startup that developed the Galea headset.

Another application of the technology, is to give people with spinal injuries or other forms of paralysis more freedom and to allow those who have lost limbs the ability to better control prosthetics.

There are different types of brain-computer interfaces and many involve actually implanting electrodes into the brain or spinal cord to either give people the ability to control a computer, or an artificial limb. However, the OpenBCI technology relies on external, non-invasive electroencephalogram readings to monitor brain activity (taken from sensors on a cap).

“The amount of control and the fidelity you have, obviously increases with the signal quality, and the best signal quality you’re going to get is by putting electrodes down into the brain,” says Russomanno.

“But, a lot of the magic happens in the classification and the machine learning on a case on a person by person basis. And so, this is where I think that BCI technology is going to be used for personalizing control.”

There are of course big attractions to the non-invasive nature of this technology. If the artificial intelligence and machine learning side of the software can make up for the reduced signal then it has great potential to help people in need of this technology.

Russomanno set up OpenBCI with one of his professors after leaving grad school 6 years ago. The company is unusual in that it has been developing inexpensive, non-invasive, open source brain-computer interface technology for the last 6 years.

It’s unusual as most tech companies keep the technology behind their products under high levels of secrecy. “I think it’s super important that that innovation takes place in the public domain, in a way where people have a variety of backgrounds and disciplines can contribute,” emphasizes Russomanno.

“It doesn’t take place behind closed doors where the incentives of what’s being put into the world, and what’s being used by the users, can be misaligned with the best interest of the users themselves.”

Since the company started, many tech companies and researchers have used the OpenBCI tech to develop

J&O Mixed Veggie Dip Cups Recalled Over Egg Allergy Concerns

KEY POINTS

  • The product was distributed in Colorado, Kansas, South Dakota, Wyoming and New Mexico
  • FDA said egg was listed as one of the ingredients of the ranch dressing but it was not mentioned on its label
  • No adverse reactions related to the recalled product have been reported

Minnesota-based Russ Davis Wholesale is recalling its Mixed Veggie Cup with Dip due to “undeclared egg” content in it. People with egg allergy may experience an allergic reaction if they consume the product, the company warns.

The issue was reportedly discovered during a routine label audit when the company’s quality control team noted that egg was listed as one of the ingredients of the ranch dressing but it was not mentioned on the label.

“The Mixed Veggie Cup with Dip was distributed in Colorado, Kansas, South Dakota, Wyoming, New Mexico in higher education, health care and corporate campus’ in grab ‘n go coolers,” the Food and Drug Administration (FDA) announced Thursday.

The affected products are labeled as J&O Mixed Veggie Cup with Dip in 5.o-ounce plastic containers with a sell-by date from Sept. 30 to Nov. 2, 2020.

No adverse reactions related to the recalled products have been reported so far but the company warns of possible “serious” or “life-threatening” allergic reactions in people who are sensitive to eggs if they consume the product. It has asked those who have purchased the product to dispose of it. 

Customers who have any questions related to the recall can contact the company at 877-433-2173.

According to the American College of Allergy, Asthma & Immunology (ACAAI), egg allergy is actually one of the most  common allergies, especially in children. People who are allergic to chicken eggs may also be allergic to other types of eggs including quail and turkey.

“Experts estimate that as many as 2% of children are allergic to eggs,” the ACAAI noted. “Fortunately, studies show that about 70% of children with an egg allergy will outgrow the condition by age 16.”

Common symptoms of egg allergy include skin reactions such as hives, difficulty in breathing, sneezing or runny nose, watery eyes, or stomach pain after eating or even just by touching eggs. A less common but life-threatening reaction is anaphylaxis, which requires immediate medical treatment.

Although egg allergy is quite common, it is an ingredient that usually remains hidden in products. This is why the FDA lists it as one of the eight allergens to be included on the ingredients label of packaged food products “in clear language”.
