Quotes About Brain

Nothing about a brain, when surveyed as a physical system, suggests that it is a locus of experience. Were we not already brimming with consciousness ourselves, we would find no evidence for it in the universe—nor would we have any notion of the many experiential states that it gives rise to. The only proof that it is like something to be you at this moment is the fact (obvious only to you) that it is like something to be you.10

Aesthetic experiences are still, more than likely, internal excitations of the brain, as we see from the fact that ingesting recreational drugs can bring on even more intense experiences of transcendence. And the particular triggers for natural aesthetic experiences are readily explicable from the evolutionary pressures that have shaped the perceptual systems of human beings

Despite our attachment to the notion of free will, most of us know that disorders of the brain can trump the best intentions of the mind.

The indeterminacy specific to quantum mechanics offers no foothold: If my brain is a quantum computer, the brain of a fly is likely to be a quantum computer, too. Do flies enjoy free will?

All psychoactive drugs modulate the existing neurochemistry of the brain—either by mimicking specific neurotransmitters or by causing the neurotransmitters themselves to be more or less active. Everything that one can experience on a drug is, at some level, an expression of the brain's potential.

early stress increases the size of the amygdalae. One study found that an eight-week program of mindfulness meditation reduced the volume of the right basolateral amygdala, and these changes were correlated with a subjective decrease in stress.

There is nothing spooky about mindfulness. It is simply a state of clear, nonjudgmental, and undistracted attention to the contents of consciousness, whether pleasant or unpleasant. Cultivating this quality of mind has been shown to reduce pain, anxiety, and depression; improve cognitive function; and even produce changes in gray matter density in regions of the brain related to learning and memory, emotional regulation, and self-awareness.

There is now a large literature on the psychological benefits of meditation. Different techniques produce long-lasting changes in attention, emotion, cognition, and pain perception, and these correlate with both structural and functional changes in the brain.

Nutritional deficiencies of omega 3 essential fatty acids, vitamin D, antioxidants, minerals and some amino acids can lead to chemical imbalances in the brain which can lead to emotional illness and cognitive decline. Deficiencies of folic acid and vitamin B6 can predispose an individual to depression, and cause that individual to not respond to antidepressant medication.

But my subconscious mind--the part I've heard writers call the lizard brain--could and did: it told me to reach for Anne Lamott or Edith Wharton or Calvin Trillin instead. And if I've learned one thing in my decades on earth, it's this: Don't argue with your lizard brain; it knows you better than you know yourself.

Positivity is far more than a mental preference. It changes your brain, literally, and it changes the people around you. It's the nearest thing we have to magic.

There is more information in one thimble of reality than can be understood by a galaxy of human brains. It is beyond the human brain to understand the world and its environment, so the brain compensates by creating simplified illusions that act as a replacement for understanding.

What does it mean to feel something similar to the way God feels? Is that like saying a pebble is similar to the sun because both are round?" he responded. "Maybe God designed our brains to feel love the same way he feels it. He could do that if he wanted to.

The human mind is a delusion generator, not a window to truth. Everyone, including skeptics, will generate delusions that match their views. That is how a normal and healthy brain works. Skeptics are not exempt from self-delusion.

We think we are reasonable and rational most of the time. But what hypnotists have long known, and scientists have in recent years confirmed, is that our decisions are often made without appeal to the rational parts of our brains. We literally make our decisions first and then create elaborate rationalizations for them after the fact.

In this sort of situation, all it takes is one idiot to suggest witchcraft as the problem, and from that point on, confirmation bias does the rest. Once your brain filter is set to look for witches, all evidence fits into the "witch" frame.

Humans will always think in terms of goals. Our brains are wired that way. But goals make sense only if you also have a system that moves you in the right direction.

The reality one learns while practicing hypnosis is that we make our decisions first—for irrational reasons—and we rationalize them later as having something to do with facts and reason. If you believe humans are fundamentally rational, you will have a hard time learning to be a hypnotist because hypnotists rely on our irrational brain wiring to persuade. The most effective politicians do the same.

We know the brain creates illusions because there are so many competing religions in the world. Assuming you picked the right religion, all of those other poor souls are living in a deep illusion. Your neighbor might think he remembers his previous life, while you think you saw God during your heart bypass surgery. You can't both be right. But you could both be wrong, and both of you might be experiencing delusions of reality that somehow don't kill you.

You've heard the old saying that knowledge is power. But knowledge of psychology is the purest form of that power. No matter what you're doing or how well you're doing it, you can benefit from a deeper understanding of how the mind interprets its world using only the clues that somehow find a way into your brain through the holes in your skull. When

Exposure to horrible and frightening thoughts can elevate your stress, which releases cortisol. The Mayo Clinic website explains that cortisol "curbs functions that would be nonessential or detrimental in a fight-or-flight situation. It alters immune system responses and suppresses the digestive system, the reproductive system and growth processes. This complex natural alarm system also communicates with regions of your brain that control mood, motivation and fear.
