A new book from the author of Amazon's longest-running bestseller, "I Thought I Was Dead."
What a Stroke-Suffering Neurologist Learned About the Brain After It Stopped Working
Neuroscientist Jaeseung Jeong strongly recommends psychiatrist Jiyong Kim from "Brain Rich People."

The second book by Jill Bolte Taylor, the first neuroscientist to observe the process of brain collapse after suffering a stroke at age 37.
The author, who was studying the brain at Harvard University, gained attention in a TED talk after sharing his experience of living with only the right brain after suffering from left brain damage.

Even at the moment of his brain collapse, he thought, “A stroke for a neuroscientist? How cool!” As a relentless neuroscientist, and as a human who personally experienced the brain’s resilience by learning numbers and language one by one with a damaged left brain, this time he focuses on ‘the working principles of the mind based on brain science.’
It reveals the intimate mechanisms of the brain and emotions and presents tools for a whole-brain life in simple and clear language.

If we truly want to know ourselves, if we want to take control of our lives, we must study the brain science behind our emotions.
Understanding how the brain works behind emotions allows us to be less dependent on our emotions and gives us the power to choose how we feel.
This is the 'whole-brained life' and subjective life that this book emphasizes.

The world of emotions discovered by neuroscientists is deep and wonderful.
Let's delve into the anatomy of the brain and mind through the eyes of a scientist, and the story of one human being who has endured the suffering that exists beyond.
'

After brain surgery, I regained the ability to experience new emotions.
But I had to relearn how to name the emotions I was experiencing.
I remember describing one element of pain.
My heart was racing, my jaw was twitching, the hair on the back of my neck was prickling, my hands were clenched into fists, and sweat was breaking out on my skin.
I felt like an animal wandering in the wild.
I wanted to hit, bite, and attack with all my might.
My mother said that a series of such states were anger.
From then on, I could sense when my anger circuitry was triggered.

But no matter how hard I tried, I couldn't understand why people kept engaging in the anger circuit and making it work.
Because the anger came across as too violent and internally unhealthy.
And by paying attention to the early signs of anger, I realized that I had the power to control it.
All you had to do was stop the circuit before it completely rotated.
As time passed and my character 2 recovered, I discovered that even if the circuit was triggered, it took less than 90 seconds for a particular neural loop to start working and then completely stop.
--- p.124

I mitigate Character 2's hostility by recognizing that Character 2 is in a triggered state.
Then quickly press the stop button.
Intentionally appeases Character 2 before saying or doing something they might later regret.
Feeling shame or guilt about Character 2's wiring will only serve to distract you from your attempts to heal Character 2.
So when character 2 is triggered, we use the 90-second rule.
It gives you time to take a break or start over, such as counting to ten.

After writing "I Thought I Was Dead," I had no intention of writing another book, but I felt like I had something important to say.
We have an amygdala, hippocampus, and anterior cingulate gyrus, one in each hemisphere, which are involved in emotional
I realized that the system is functionally separate, but most people don't know this.
That's why people have a hard time controlling their emotional reactivity.
If we believe we have no choice, we act automatically.
When we understand the anatomy that underlies our choices, we gain the power not only to not react to stimuli, but also to make informed decisions.

One of the many beautiful things about the four character system is that when we open ourselves to the four characters, they have the power to shape every moment of our lives in a very positive way.
This book deals with how to love not only the four characters within ourselves, but also the four characters in others.

Every human being has a wonderful brain with four characters, and the ability to choose which of the four characters to embody at any given moment.

If we train our brain, we can easily switch between the four characters.
This allows new connections to be formed between different brain cell modules.
By using this network to bring the four characters into your brain conversation at any time, you can live a purposeful life in your best form.
Every human being has a wonderful brain with four characters, and the ability to choose which of the four characters to embody at any given moment.

When we realize that every ability we have depends on the cells that perform that function, we become more aware of the fact that the brain is a very intricately woven network of cells, and that our emotions, experiential feelings, thoughts, and behaviors are simply the workings of a network of cells.
Feeling joy or feeling misery is due to the wiring of the brain.
We have the power to choose how much of each circuit we activate, and how we feel about it.
You can choose to disconnect from the emotion early, feel the corresponding circuits in your body working, and then let them go after 90 seconds.
Or you can just act out your feelings for 90 seconds.
Alternatively, you could re-activate that circuit and feel that feeling over and over again for 90 minutes, or 90 years.
