Your Brain on Fear

2008-01-09 06:10:54 by schneier in Schneier on Security
 
...brain's fear circuitry makes it more powerful than the brain's reasoning faculties. The amygdala sprouts a profusion of connections to higher brain regions -- neurons that carry one-way traffic from amygdala to neocortex. Few connections run from the cortex to the amygdala, however. That allows the amygdala to override the products of the...

Risk and the Brain

2008-03-18 06:51:31 by schneier in Schneier on Security
 
...brain estimates risk: Using functional imaging in a simple gambling task in which risk was constantly changed, the researchers discovered that an early activation of the anterior insula of the brain was associated with mistakes in predicting risk The time course of the activation also indicated a role in rapid updating, suggesting that this...

...brain waves? I often write about studies that show no connection between electromagnetic radiation and health, so it's only fair I highlight credible ones that suggest a connection. In what appears to be two well-conducted and well-controlled studies, cell phones appeared to affect alpha waves (related to one's focus on external v. internal...

Risk of Knowing Too Much About Risk

2008-03-06 06:24:50 by schneier in Schneier on Security
 
...brains process risk, which is in two ways. The first is intuitive, emotional and experience based. Not only do we fear more what we can't control, but we also fear more what we can imagine or what we experience. This seems to be an evolutionary survival mechanism. In the presence of uncertainty, fear is a valuable defense. Our brains react...
