The key to happiness hidden in the insula, a secret part of the brain

Mathieu Ricard, a Tibetan Buddhist monk known as 'the happiest man in the world'.
When scientists measured and studied his brain waves, they found that he had characteristics that were different from those of ordinary people.
The brain also has areas that correspond to the 'accelerator' and 'brake' of a car.
Just like how a car works, when we focus on something, the accelerator area of ​​our brain is activated, and when we stop, the brake area is activated.
Also, when the axel area is activated, people think positively and feel happy.
The EEG study examined the brain's axon activity, and the monk Mathieu Ricard had the highest axon activity among 1,000 subjects.
His brain activity was usually about 100 times higher than that of an average person, but there were times when it was even higher.
It was at that time that I was meditating, full of altruism, praying for world peace and the happiness of humanity.
At this time, his brain activity was more than five times higher than usual, and 500 times higher than that of an average person.

Stimulating the insular cortex can help you use your brain in a balanced way.
What is noteworthy in the study of monk Mathieu Ricard is that the moments when his brain's accelerator activity was high, that is, when he was happiest, were 'when he was meditating with a sense of altruism, wishing for world peace and human happiness.'
At this time, his brain was in a selfless state.
Selflessness, which can be directly translated as 'selfless', refers to a state in which the entire brain is used evenly and in a balanced manner.
To use our brains evenly, we need to go back to the insula.
Because if you train your insular cortex, you can use your entire brain.
Therefore, in order to become happy, we need to intentionally and consistently train our insular cortex.
There are moments in our daily lives when the insular cortex, the secret part of the brain that brings happiness, is trained and stimulated.
When we encounter text, music, or pictures, emotions or feelings arise, when multiple senses are integrated, when social interactions occur, when we empathize with others, and when we begin to focus on something.
In this way, the brain constantly changes and grows as a person lives, changing the mind and even life.

6 Brain Training Techniques That Scientifically Boost Happiness
The author, a neuroscientist, discovered six brain training methods to become happier through 25 years of research.
First, if you have a grateful heart in everything, your brain circuits will change positively.
Second, if you have a positive mindset, your entire brain becomes activated and you become closer to happiness.
Third, spending time with like-minded people strengthens the insular cortex.
Fourth, cultivating altruism improves brain function.
Fifth, practicing mindfulness stops brain aging.
Sixth, experiencing nature changes our lives.
The author has maintained his happiness by training his brain for a certain amount of time every day.
Because I personally realized that this is the way to increase mental resilience and change into a happy life.

The Science of Happiness: Empathy, Consideration, and Altruism
On the other hand, the brain's balance may be disrupted and you may become unhappy.
The author warns that this can happen especially when selfishness is strong, because when selfishness is strong, the brain's circuits are disconnected, the overall brain balance is disrupted, and brain function is dulled as a result.
It has been proven through neuroscience that selfishness has a negative impact not only on others but also on oneself.
Unlike selfishness, altruism, which is about helping others, enhances our brain function.
Altruistic behavior based on empathy for others activates brain function, and the moment you empathize with others, dopamine is secreted in the brain, making you feel pleasure.
The author recommends using both empathy and altruism, saying, above all, that "the brain is inherently designed to be altruistic."
When we conducted an experiment that controlled the part of the brain that controls emotions, it was shown that altruistic behavior increased.
Increasing altruism and empathizing with others are all ways to make yourself happy.
The saying that 'living well will lead to losses', which was once taken for granted, can now be comfortably forgotten.
