One of my favourite nerves, a true lady of peace!
The sense of what is going on inside of our body, how our organs "feel" (or interoception) is quite difficult to study, as it has thousands of various branches and processes gazillions of signals. Perhaps because of this we understood very little of the importance of the vagus nerve role, which is a true primadona in this chorus of signals, the conductor of the whole system of relaxation and healing.
When the signal reaches the brain, it "talks" not only to the brain stem, but also to various brain regions (for example, there is a specific area that is connected to vagal neurons, that trigger nausea). Current research shows that vagus nerve is also an active participant in processes of memory, learning, motivation, emotion control - perhaps this is why eating may create sense of pleasure, and artificial stimulation of vagus nerve may alleviate symptoms of depression.
In the article you will find descriptions of other interesting research results, while I will remind you that natural arousal of vagus nerve (which induces the state of rest and healing) may be achieved by calm and rhythmical breathing, stretching the long skeletal muscles (legs or back), massaging sides of the neck or washing your face with cold water.

Early autumn is a great time to talk about mushrooms.
This study was performed with the help of mice (thank you, again, even if you did not ask for it - hopefully this one was beneficial). One dose of psilocybin has increased the density and size of the dendritic spines due to their increased growth. The effect was rapid, visible after 24 hours after the effect, and still significant after one month. Other results indicate that this effect decreased stress induced behavior deficit (or "cured" the learned helplessness) and increased the excitatory neural signals - probably newly formed nerve connections allowed to form and express new behaviors.
Just in case - psilocybin is a known hallucinogenic substance, usually produced from mushrooms, but little researched because it carries a stigma of being a drug.
No, I still do not encourage you to take on individual experimenting with mushrooms, but scientific research would be so awesome!

Research. Apparently, we are still evolving! Programming code is not activating the usual suspect brain regions - math, language or logic. Such type of activity rather activates a so called multiple demand network, which processes several signals from different areas of the brain and both hemispheres. Sounds quite renaissance!
With, that, I demand that IT profession is classified as exact science!
OK OK, just kidding. But still, brings a whole another perspective on how we think. And code.
