...fall into the same trap. But when his teenage daughter planned a long-distance swim last summer, Sunstein found himself dwelling on the remote possibility she would drown. "It's crazy," says Sunstein, a University of Chicago law professor specializing in risk regulation. "But I couldn't counteract my brain's rapid, intuitive emotional system for evaluating risk...
...Emotion Machine” is a complement to Minsky’s last work, “The Society of Mind,” which put forth a number of radical ideas about the human brain. “The Emotion Machine,” on the other hand, focuses on how mechanical processes of the brain actually work...
...probe the risk-assessment mechanisms of the human mind, Joseph LeDoux, a professor of neuroscience at New York University and the author of The Emotional Brain, studies fear pathways in laboratory animals. He explains that the jumpiest part of the brain--of mouse and man--is the amygdala, a primitive, almond-shaped clump of tissue that sits just above the brainstem. When you spot potential danger--a stick in the grass that may be a snake, a shadow around a corner that could be a mugger--it's the amygdala that reacts the most dramatically, triggering the fight-or-flight...
...until a fraction of a second later that the higher regions of the brain get the signal and begin to sort out whether the danger is real. But that fraction of a second causes us to experience the fear far more vividly than we do the rational response--an advantage that doesn't disappear with time. The brain is wired in such a way that nerve signals travel more readily from the amygdala to the upper regions than from the upper regions back down. Setting off your internal alarm is quite easy, but shutting it down takes some doing...
...point gets calibrated, but evidence suggests that it is a mix of genetic and environmental variables. In a study at the University of Delaware in 2000, researchers used personality surveys to evaluate the risk-taking behavior of 260 college students and correlated it with existing research on the brain and blood chemistry of people with thrill-seeking personalities or certain emotional disorders. Their findings support the estimate that about 40% of the high-thrill temperament is learned and 60% inherited, with telltale differences in such relevant brain chemicals as serotonin, which helps inhibit impulsive behavior and may be in short...
