Over the last year, we’ve created then shared VR with thousands of people around the world, mostly terminally ill and aging World War II, Korea and Vietnam Veterans who can’t physically travel to see their memorials in Washington, DC. (If you know a Veteran who isn’t able to travel, tell them about our VR film honoreverywhere.com ) Each time we share, we notice how the content appears to influence the Veterans’ body and demeanor. Their arms and legs appear to have more energy. They are emotional. They tell us they didn’t just watch the video, they felt it.

In his own words, here’s a peek at Dr. Tarrant’s preliminary findings on VR video’s effect on fast and slow brain waves as it relates to immersive mindfulness experiences.

Virtual Reality Meditation: Changes in Brainwave Activity and Heart Rate Variability http://drjefftarrant.com/2016/08/your-brain-on-vr-mindfulness-in-nature/ Popular articles that discuss brainwaves in relation to states of consciousness often simplify matters by indicating that there are four types of brain waves: Delta, Theta, Alpha and Beta. Delta, Theta and Alpha can all be considered “slow” brainwaves. When they are dominant, the brain is often in a more relaxed or quiet state. Beta and brainwaves faster than beta, such as high beta or gamma, can be considered “fast” brainwaves. When these are dominant, the brain is active and engaged. We need these brainwaves to be flexible and fluid, shifting and changing with whatever task we give our brain. For example, when it is time to rest we expect slow brainwaves to increase and fast brainwaves to decrease. When we are balancing the checkbook or making an important decision, we expect the opposite pattern. By measuring brainwaves before and after a specific task or experience, we can get a picture of how the brain was impacted; did it become more alert and aroused or more relaxed and quiet?

We wanted to know how the brain responds when someone engages in a virtual reality meditation, so we used quantitative EEG technology to tell us. First, we oriented our volunteer subject to Virtual Reality by having them watch 2 different StoryUp immersive stories. After the orientation we obtained a baseline measurement of their brainwaves using a 19 channel EEG system. The volunteer then participated in a 4 minute mindfulness in nature immersive experience after which we measured the brainwaves one more time. Overall, the results showed a significant quieting of the brain after experiencing the brief VR meditation, measured by decreases in fast activity (gamma) and increases in slow activity (theta and alpha). This, by itself, was impressive given the relatively brief exposure to the meditation. Perhaps more importantly, an analysis of specific brain regions impacted by the VR meditation showed that areas of the brain involved in the stress response were some of the most significantly impacted. Below are 3D brain images showing changes in the brain after the VR meditation. Cooler colors (blues) indicate that the activity measured has decreased whereas brighter colors (yellow, orange, red) indicate that activity has increased. The first picture is looking at fast brainwave activity (gamma) in the anterior cingulate. Blue colors indicate that gamma activity decreased significantly during the meditation. This is important because this part of the brain often becomes over activated during stress and anxiety or when we become fixated on thoughts, feelings or behaviors. By helping this area to relax, the brain is shifting into a more relaxed, peaceful state.

Decreased Gamma Activity during an immersive experience

In the next image, we switch from examining fast brainwaves to looking at slow brainwaves. In particular, we are looking at alpha activity in the Precuneus. This part of the brain is the hub of the brain’s Default Mode Network (DMN). When the DMN is quieter, as seen here, this suggests that the person is not thinking about themselves (or their worries) as much, which is exactly what we would hope to see during this experience.
