“For the artist, the goal of the painting or musical composition is not to convey literal truth, but an aspect of a universal truth that if successful, will continue to move and to touch people even as contexts, societies and cultures change. For the scientist, the goal of a theory is to convey "truth for now"--to replace an old truth, while accepting that someday this theory, too, will ve replaced by a new "truth," because that is the way science advances.”

“The Greek physicians Herophilus and Erasistratus discovered the nervous system in 322 BC, placing the seat of thought in the brain. It might be fair to say that they were the first neuroscientists. Previously, Aristotle and others thought the brain's function was simply to cool the blood, due to it's many folds and creases.”

“But there is a critical point about differences between individuals that exerts arguably more influence on worker productivity than any other. The factor is locus of control, a fancy name for how people view their autonomy and agency in the world. People with an internal locus of control believe that they are responsible for (or at least can influence) their own fates and life outcomes. They may or may not feel they are leaders, but they feel that they are essentially in charge of their lives. Those with an external locus of control see themselves as relatively powerless pawns in some game played by others; they believe that other people, environmental forces, the weather, malevolent gods, the alignment of celestial bodies-- basically any and all external events-- exert the most influence on their lives.”

“Part of our primate heritage is that most of us want to feel that we fit in somewhere and are part of a group. Which group we're part of may matter less to some of us than others, as long as we're part of a group and not left entirely on our own. Although there are individual differences, being alone for too long causes neuro-chemical changes that can result in hallucinations, depression, suicidal thoughts, violent behaviors, and even psychosis. Social isolation is also a risk factor for cardiac arrest and death, even more so than smoking.”

“Herman Pontzer, an evolutionary anthropologist at Duke, studies health among hunter-gatherer societies whose lifestyles are similar to those of our ancestors. He found that they generally exhibit excellent health in spite of following a wide range of diets. It doesn't matter if they get 80% of their calories from carbohydrates, or from animal fat, or from nuts and berries - almost all eat more fiber than the average American, but that is about the only difference. (This takes the wind out of the paleo diet.) Interestingly, they don't shun sugar, consuming it in the form of honey. Notably they don't have access to processed foods of or deep-fried foods.”

“The prefrontal cortex is what we use to se goals, make plans, divide a large project up into smaller pieces, exercise impulse control, and decide what we're going to pay attention to. As I mentioned earlier, the prefrontal cortex is the last region to develop in childhood and doesn't fully mature until well after puberty - into the late twenties. Because of it's involvement in impulse control, there have been several cases in which defense attorneys argued that eighteen-to-twenty-year-olds shouldn't be held responsible for law-breaking acts because they lack an adult like, mature prefrontal cortex that would allow them to exercise adult-like impulse control. The prefrontal cortex is also the first cortical region to show wear and tear as we get older. "That is why one of the most significant problems in older adults is the ability to keep track of thoughts and prevent stray ones from interfering," says Art Shimamura. "Brain fitness as we age depends significantly on maintaining a healthy and active prefrontal cortex. The more we engage this brain region during daily activities, the better we will be able to control our thoughts and think flexibly.”

“Access is one of those words that should raise red flags when you encounter them in statistics. People having access to health care might simply mean they live near a medical facility, not that the facility would admit them or that they could pay for it. As you learned above, C-SPAN is available in 100 million homes, but that doesn’t mean that 100 million people are watching it. I could claim that 90 percent of the world’s population has “access” to Weaponized Lies by showing that 90 percent of the population is within twenty-five miles of an Internet connection, rail line, road, landing strip, port, or dogsled route.”

“If music serves to convey feelings through the interaction of physical gestures and sound, the musician needs his brain state to match the emotional state he is trying to express. Although the studies haven't been performed yet, I'm willing to bet that when B.B. King is playing the blues and when he is feeling the blues, the neural signatures are very similar. (Of course there will be differences, too, and part of the scientific hurdle will be subtracting out the processes involved in issuing motor commands and listening to music, versus just sitting on a chair, head in hands, and feeling down.) And as listeners, there is every reason to believe that some of our brain states will match those of the musicians we are listening to.”
