A Quote by Neal Stephenson

The only thing that can effect a big change in personality is something that physically rewires the brain and/or alters the body's chemical milieu. — © Neal Stephenson
The only thing that can effect a big change in personality is something that physically rewires the brain and/or alters the body's chemical milieu.
What you do and learn in life physically changes what your brain looks like—it literally rewires it.
Sleep is simply a chemical change in our brain and body (melatonin) - It?s not a place we go, it is a state of being that we fall into.
As other authors have realized, heat can have a strange effect on us, can cause odd chemical reactions in the brain. Heat can bring out secrets; it can change people's personalities.
Men do not knowingly drink for the effect alcohol produces on the body. What they drink for is the brain-effect; and if it must come through the body, so much the worse for the body.
One of the things cognitive science teaches us is that when people define their very identity by a worldview, or a narrative, or a mode of thought, they are unlikely to change-for the simple reason that it is physically part of their brain, and so many other aspects of their brain structure would also have to change; that change is highly unlikely.
Much of what we now consider 'personality' will be explained away as structural and chemical functions of the brain.
Are you on the eve of change? Embrace it. Accept it. Don't resist it. Change is not only a part of life, change is a necessary part of God's strategy. To use us to change the world, he alters our assignments.
I wouldn't change a single thing, because one change alters every moment that follows it.
Contemporary philosophers are facing problems that were unthinkable only one century ago, such as whether space and time are mutually Independent, whether there is objective chance or only uncertainty, whether physics can explain chemical change, whether our behavior is fully determined by our genomes, whether ideation can change the brain, or whether either the economy or ideas are the ultimate roots of the social.
At 15, I refereed my first match, and I was training at my dad's school even prior to that, so the only thing that I was concerned about - I guess the only thing that made me reluctant and was the reason I was in L.A. and the reason I went to acting school - was I thought maybe I wasn't big enough - physically big enough - to compete with WWE.
Dopamine is a chemical released in your brain and your body when you sleep that paralyzes your body so you don't act out your dreams.
People say the effect is only on the mind. It is no such thing. The effect is on the body, too. Little as we know about the way in which we are affected by form, by color, and light, we do know this, that they have an actual physical effect. Variety of form and brilliancy of color in the objects presented to patients, are actual means of recovery.
We have allowed brain thinking to develop and dominate our lives. As a consequence, we are at war within ourselves. The brain desiring things which the body does not want, and the body desiring things which the brain does not allow; the brain giving directions which the body will not follow, and the body giving impulses which the brain cannot
Every thought, feeling, and emotion creates a molecule known as a neuropeptide. Neuropeptides travel throughout your body and hook onto receptor sites of cells and neurons. Your brain takes in the information, converts it into chemicals, and lets your whole body know if there's trouble in the world or cause for celebration. Your body is directly influenced as these molecules course through the bloodstream, delivering the energetic effect of whatever your brain is thinking and feeling.
From my studies of genetics and neuroscience I have come to believe that people fall into four broad personality types - each influenced by a different brain chemical: I call them the Explorer, Builder, Director, and Negotiator.
I think that everyone in one way or another has some sort of body issue. There's something about themselves physically that they're not happy with, that they're ashamed of, that they keep constantly trying to change.
