Stress Inhibits Brain's Ability to Grow

Travoltus writes "Dr. Professor Elizabeth Gould claims to have shown that, with marmoset primates, stress causes the brain to switch to survival mode in which it thinks only about survival; it simply does not invest new cells in other, more complex thought processes. Dr. Gould also suggests that poverty has an adverse effect on the brain. Dr. Gould is a Princeton researcher who concentrates on studying adult neurogenesis, a phenomenon that, 20 years ago, most scientists believed did not occur."

The article actually goes into that.

"The social implications of this research are staggering. If boring environments, stressful noises, and the primate's particular slot in the dominance hierarchy all shape the architecture of the brain--and Gould's team has shown that they do--then the playing field isn't level. Poverty and stress aren't just an idea: they are an anatomy. Some brains never even have a chance."

Now, I don't think that poverty alone would cause the stifled neurogenesis they're talking about, but if you combine it with a lot of the other stressful things that tend to come along with poverty (crime-filled environment, fractured/broken families, poor education), that might do it.
