Recent articles highlight the research on the link between poverty and brain development and function. In summary, poor children whose parents were not very nurturing were likely to have less gray matter, which is linked to intelligence, and white matter, which is linked to the brain’s ability to transmit signals. These children also showed greater problems regulating their emotions as adults. Finally, a series of experiments showed that poverty imposed such a burden that there was little mental capacity left to accomplish fundamental life skills, let alone tasks that might lift the person out of poverty.
