Correct breathing can help reduce stress and counteract mental imbalances. Doctors are looking for a connection between breathing and stress reduction. Researchers have now found some nerve cells in the brainstem that connect breathing to states of the mind. This could explain how we regulate stress through our breathing, and researchers at Stanford University School of Medicine researched the reason why calm, controlled breathing helps with stress. There is a connection between breathing and states of our mind. The medical professionals released a press release on the results of their study, What Do Pranayama Breathing Exercises Do?
Doctors sometimes prescribe breathing exercises for people with stress disorders. These include, for example, pranayama breathing exercises in yoga. This technique can shift awareness from a stressed or hectic state to a meditative state, the experts say. This type of breathing is practically a core component of all forms of yoga. The current study is fascinating because it offers a cellular and molecular understanding of how this effect might work, explains author Dr. Kevin Yackle: Why does controlled breathing make us calmer? The tiny group of neurons that associate breathing with relaxation, attention, excitement, and fear is located deep in the brain stem. About 175 neurons from a cluster of almost 3,000 neurons, which control autonomic breathing, are responsible for communication between breathing and parts of the brain, which in turn are responsible for attention, arousal and panic. Our breathing rate could therefore directly influence whether we feel calm or anxious, for example, explain the medical professionals. This connection has already been established in an experiment on mice. If the connection works similarly in humans, this could explain why slow controlled breathing makes us calmer, the scientists say. Experts inactivate certain neurons For their study, the researchers first divided the 3,000 neurons based on their genetics because neurons with similar genes are similar Roles in the brain. This is how the experts came across the special 175 neurons. The next challenge was to uncover what the neurons did, say the researchers. Sometimes the best way to see how something works is to see what happens when it’s gone, the scientists said. For this reason, they deactivated the neurons individually and then examined the effect. Bacteria kill the neurons. To do this, the researchers first bred genetically engineered mice. These had receptors for a toxin that only affects the neurons. For example, the neurons of the infected mice could be killed by bacteria, which also cause diphtheria, say the medical experts .
In the experimental animals, the toxin was able to kill 175 neurons. In this way, these neurons were switched off, but the rest remained intact and fully functional, the scientists continued. Eventually, the researchers saw how the loss of these neurons affected the mice’s breathing and behavior. No effects to be seen at first We expected that inactivating the neurons could completely eliminate or dramatically change the mice’s breathing pattern, explains Stanford author Professor Mark Krasnow University School of Medicine. But there was no change in the animals’ breathing pattern. For a few days the researchers thought they had made a mistake in their experiment and the attempt had failed. After a while, the mice’s breathing and behavior changed. After a few more attempts and some time passed, the scientists finally realized that there was a change in the Mice. The authors of the study report that the animals were extraordinarily calm for mice. For example, exposure to a new environment usually causes the mice to sniff and explore the area excitedly. Instead, the treated mice just sat around and tended to themselves. On closer inspection, the animals also breathed more slowly, say the medical professionals. More research is needed, This clearly shows a connection between breathing, behavior and the inactive 175 neurons. We hope to understand the function of this center on therapies.
