With the recent and exciting Neuroscience discoveries associated with 40Hz Gamma light therapy treatment for the brain, users are rapidly looking to buy a system that provides this type of therapy.  However, during this quest to find and purchase a Gamma light therapy system, users should understand that there are choices associated with the total treatment area and zones to be serviced by these systems and their associated pros and cons for these different approaches. There are definite advantages to devices that offer large treatment area to the face and brain.

Several manufactures are sprinting to complete their design and development of their products to provide Gamma treatment to users. In many of these cases these manufactures didn’t take a systematic view to defining what the total treatment area should be for Gamma treatment before finalizing their consumer product. In most cases, manufactures were looking to provide the lowest cost system they could and not define one that would provide the most comprehensive and effective treatment to the user. 

This has led manufacturers to a design that solely targets the eyes via a goggle system. While some goggle systems have had some encouraging results in clinical trials such as documented by Cognito. Users should understand that a goggle only system has some major disadvantages. By employing googles for improving brain function, the user may be missing out on other beneficial effects that are available from other Gamma light therapy treatments. A dome or hood type of system is key to receiving additional benefits by providing a large treatment zone that exposes the entire face, brain, and eyes.  

A dome design not only encompasses all the benefits provided by the Goggles, it also provides more total energy and exposure to the body and brain. These additional advantages include increasing the treatment area for anti-inflammation and the ability to generate greater light (energy) absorption and expansion through the entire brain and body. In this discussion we describe some of the differences between Dome/Hood systems vs Goggles systems and their advantages and disadvantages so the user can make a proper and informed decision when purchasing a Gamma light therapy system.

Photobiomodulation (light therapy) delivery systems that incorporate goggles can deliver 40 light flicker to the orbital areas and, through the retina and optic nerves and radiations, and eventually can deliver a 40 Hz neuronal impulse to the occipital cortex. This means that goggles that deliver Red and Near-Infrared light (not just white light) are theoretically able to increase ATP, circulation and also have anti-inflammatory effects on the orbital areas. In all likelihood, the areas touched directly by the Red and/or Infrared light provided by the goggles used will be the elements that receive this effect.  In addition, the 40 Hertz gamma flicker allows the creation of EEG waves which can undoubtedly propagate over the occipital lobe and possibly more of the brain’s surface area. Furthermore, if included with the goggles, 40 Hz gamma sound can be delivered to the ears and from there it can reach the 8th nerve nuclei and possibly adjacent areas of brain. This means that the benefits to brain microglia of 40 Hertz gamma maybe somewhat broader in extent than the rather narrow area likely to benefit from red and near infrared light, namely the periorbital areas. Note: that to be effective the 40hz Gamma light and sound need to be tightly synchronized with each other. 

By contrast, a dome/hood that provides full exposure to the face, head, and eyes with a significant amount of LEDs (such as provided by the Auragen System) is able to project high intensity Red as well as Near-Infrared light into the cortex of the brain’s prefrontal, parietal and temporal lobes. This means that all of the benefits of these wavelengths including anti-inflammatory effects, increased ATP formation in neuronal mitochondria, and others, are available to a far wider percentage of the brain’s cortex.  This additional area and power is important in helping users with many other issues including cognitive decline, stress and mood related issues, and long haul symptoms, like brain fog and fatigue.

In regard to long haul Covid, it is not yet known to what the extent the brain can be injured or even what form(s)of brain pathology can result from a Covid infection. According to Professor and MD, Michael Hamblin, (Harvard Medical School) et all Red and Near-Infrared light have been shown to penetrate through the scalp, skull, and meninges to depth of approximately 1/2 to 1 centimeter into the cortex of the brain tissue itself. This means that cortical neuronal tissue that has been diffusely, microscopically damaged during COVID, whether due to the virus or due to the body's response to the virus, can be reached by the Red and Near-Infrared light. The ensuing increase in mitochondrial ATP production could then result in increased performance which might last from hours to days, and which could then be replenished by another PBM session.

Alleviation symptoms lasting for hours could result, due to the improved neuronal performance made possible by the newly augmented neuronal ATP production, stimulated from this external source of energy. Conceivably resulting, in a significant symptomatic improvement for symptoms caused by diffuse damage to cortical neurons as may will be the case in Covid long haulers.   

The psychiatric benefits could be very significant, especially in patients who are becoming depressed and/or anxious after weeks of being unable to function normally, return to work, and even perform daily activities due to the brain injury they have suffered. Since COVID appears to result in significant inflammatory damage to the brain, as well as in diffuse micro vascular blockage even down to the capillary level, it is important to remember that both of these sorts of injury can happen in any part of the brain.

Understanding this fact is important, as goggles are unable to deliver Red or Near-Infrared light, anywhere but to the area directly under the two lenses of the goggles. In contrast, the Auragen dome can theoretically reach any part of the cortex as described above, resulting in a decrease in inflammation and an increase in circulation in areas of cortex all over the brain. This could result in healing for areas where either inflammatory damage or microscopic vascular damage has occurred.

In addition to providing Gamma treatment to the entire face, having a unit, like the Auragen, that provides additional features such as Theta Brainwave Entrainment for deep relaxation, Blue-Turquoise light therapy for SAD and sleep issues, and relaxing music, does provide the users with lots of advantages over a sub-optimized design. Auragen is a laboratory grade Photobiomodulation device. It is currently being used in laboratory research on rodents at Stanford University and university research on human subjects is in the planning stages. Auragen has been tested in terms of its accuracy in terms of sound frequency, light frequency, and light intensity. For these reasons Auragen can be used in cases that present more complexity, such as in long haul Covid, aging brain issues, and chronic fatigue.
