The Science of Tapping: What happens in our brains while we’re tapping? Results of an fMRI study

ACEP • May 27, 2021

(by Sarah Murphy, LPC) A German study presents another possible explanation for why tapping is effective: bifocal emotional processing. This functional magnetic resonance imaging (fMRI) study, conducted at Hannover Medical School in Germany by Dina Wittfoth and her colleagues, gives us a glimpse at what happens in our brains when we tap. The study adds to the growing evidence base for tapping.


The theory

Researchers wondered if tapping is effective because of bifocal emotional processing, i.e., attending to two stimuli at the same time. In this case, one stimulus was images designed to elicit feelings of disgust or fear, and the other stimulus was imaginary tapping.


The study setup

Because people in fMRI machines need to keep still, the researchers in this study asked their participants to visualize tapping.

Seventeen healthy young adults participated in the study. They were fMRI scanned twice in the same day. Between scanning sessions, they learned a tapping sequence taught by five lay practitioners. Participants chose their three favorite points to visualize tapping on during the second scanning.


Inside the machine, participants watched the disgusting or fear-inducing images. In the second scan, researchers cued participants to visualize tapping while watching the images, to “stay present with the picture while tapping” and to “be curious to see what happens.”


Study results

Participants rated the subjective unit of distress (SUD) on a scale from 0 to 10 for each image. The SUD rating decreased significantly for disgust (p= 0.001) and moderately for fear (p=0.089) in the imagined-tapping round.


The fMRI images showed that the amygdala increased activation, while the ventral anterior cingulate cortex decreased activation during the visualized-tapping scan. The dorsolateral prefrontal cortex, associated with working memory and multitasking, showed moderately more activity in the visualized-tapping scan. 


How the brain changed during visualized tapping

The anterior cingulate cortex links the emotional limbic brain to the thinking cortex. The ventral anterior cingulate cortex plays a role in sizing up a situation and processing emotional stimuli. Researchers suggested that the diminished activity in this region might indicate that this process was reduced when participants were focusing on the tapping visualization; thus, tapping seems to slow down our quick appraisals and mitigates against our fear conditioning, helping regulate our autonomic nervous system. 


It was previously thought that activity in the amygdala, which is known as a structure responsible for processing visceral emotion, would be decreased. Instead, its activity increased. Interestingly, the increased activation in the amygdala was found specifically in a subregion, the left and right sides. The sides of the amygdala work with the visual cortex. Perhaps this increased activation was due to the dual tasks of seeing and visualizing. 


Making it real

Tapping, and even imaginary tapping, seems to mitigate our “gut reactions.” Imagine a world in which people learned tapping from a young age. The practical method of emotional self-regulation would be second nature. Reinforced with regular practice, we could learn to keep our emotional reactivity at bay. What a beautiful world it could be.

After retiring from the military, I conducted individual and group therapy with combat veterans as a clinical social worker for the Department of Veterans Affairs (VA) at the VET Center in Warwick, RI. In my work, I've had many experiences showing the power of energy psychology to help heal trauma . One of these amazing stories occurred during my tenure at the VA. Veteran suffers from PTSD A 70-year old Vietnam Veteran suffered for 45 years from chronic PTSD as a result of life-threatening events he endured and injuries he sustained during combat. Let's call him Joe (not his real name). His symptoms included nightmares and waking up profusely sweating every night since he returned from the war 45 years ago. Joe also had insomnia and anger issues. Conventional therapies and medication were not able to alleviate the adverse impact of his trauma. Unfortunately, Joe's experience is common among a vast number of Veterans receiving treatment for PTSD at the VA. Energy psychology resolves trauma-related symptoms In the first energy psychology session, I introduced Joe to Emotional Freedom Techniques (EFT) and explained the process and its efficacy. During the next 6 sessions, he tapped on the EFT meridian points for 2-3 rounds on each combat trauma we addressed. While he tapped, I guided him to verbally release related negative emotions. We did this until he no longer experienced any disturbance associated with these challenging events, as determined by muscle testing. The results were inspiring. At the end of six 50-minute sessions, Joe reported that his nightmares and night sweats completely stopped, and he felt more rested, peaceful, and significantly less anxious. Joe was even able to stop taking most of his anxiety and depression medication. His wife said she noticed a huge positive shift in his demeanor. Lasting results Over the next 3 years, Joe used EFT on his own to clear other developmental traumas and negative core beliefs. During this time, he only had four nightmares during one two-week period, which were triggered by watching a war movie. Afterwards, he did not have any recurrence of PTSD symptoms. Joe felt joy that he did not experience previously, and he was more emotionally open and affectionate with his wife. This heart-warming story shows the power of EFT to heal rapidly and effectively, with results that last. It's why I love using it. Going forward What a difference could be made with Veterans and their families if the VA and Department of Defense (DOD) used energy psychology techniques like these! They would be free of the devastating impact of PTSD, have better relationships and an improved quality of life. Many ACEP members have stories of hope and healing. Let’s share them! When we tell our stories, we can help inspire practitioners to adopt energy psychology methods that are powerfully grounded in effective healingwith long-lasting outcomes.

In our quest for optimal health, longevity, and deeper connection, we often overlook the microscopic powerhouses driving every function within our bodies: the mitochondria. These remarkable cellular structures don't just produce energy—they may hold the key to extended lifespan, enhanced consciousness, and perhaps even our spiritual experiences.

Energy healing method is linked to recoveries from cancer in mice. Visualization directed at water or cotton is retrieved later for healing. Silent recordings of energy healing sessions are linked to genetic changes.
