Poverty may hinder kids’ brain development, study says
Reduced gray matter, lower test scores reported for poor children
July 20, 2015
Poverty appears to affect the brain development of children, hampering the growth of gray matter and impairing their academic performance, researchers report. Poor children tend to have as much as 10 percent less gray matter in several areas of the brain associated with academic skills, according to a study published July 20 in JAMA Pediatrics. “We used to think of poverty as a ‘social’ issue, but what we are learning now is that it is a biomedical issue that is affecting brain growth,” said senior study author Seth Pollak, a professor of psychology, pediatrics, anthropology and neuroscience at the University of Wisconsin-Madison.
The results could have profound implications for the United States, where low-income students now represent the majority of kids in public schools, the study authors said in background information. Fifty-one percent of public school students came from low-income families in 2013.
Previous studies have shown that children living in poverty tend to perform poorly in school, the authors say. They have markedly lower test scores, and do not go as far in school as their well-off peers.
To see whether this is due to some physical effect that poverty might have on a child’s brain, Pollak and his colleagues analyzed MRI scans of 389 typically developing kids aged 4 to 22, assessing the amount of gray matter in the whole brain as well as the frontal lobe, temporal lobe and hippocampus. “Gray matter contains most of the brain’s neuronal cells,” Pollak said. “In other words, other parts of the brain – like white matter – carry information from one section of the brain to another. But the gray matter is where seeing and hearing, memory, emotions, speech, decision making and self-control occur.”
Children living below 150 percent of the federal poverty level – US$ 36,375 for a family of four – had 3 percent to 4 percent less gray matter in important regions of their brain, compared to the norm, the authors found. Those in families living below the federal poverty level fared even worse, with 8 percent to 10 percent less gray matter in those same brain regions. The federal poverty level in 2015 is US$ 24,250 for a family of four. These same kids scored an average of four to seven points lower on standardized tests, the researchers said.
The team estimated that as much as 20 percent of the gap in test scores could be explained by reduced brain development. A host of poverty-related issues likely contribute to developmental lags in children’s brains, Pollak said. Low-income kids are less likely to get the type of stimulation from their parents and environment that helps the brain grow, he said. For example, they hear fewer new words, and have fewer opportunities to read or play games. Their brain development also can be affected by factors related to impoverishment, such as high stress levels, poor sleep, crowding and poor nutrition, Pollak said.
This study serves as a call to action, given what’s already known about the effects of poverty on child development, said Dr. Joan Luby, a professor of child psychiatry at Washington University School of Medicine in St. Louis. “The thing that’s really important about this study in the context of the broader literature is that there really is enough scientific evidence to take public health action at this point,” said Luby, who wrote an editorial accompanying the study. “Poverty negatively affects brain development, and we also know that early interventions are powerfully effective,” Luby said. “They are more effective than interventions later in life, and they also are cost-effective.”

Opportunity Cost
This phenomenon goes by the name of ‘opportunity cost,’ since by not investing in more equipment and a more rigid production flow, the company is forgoing the opportunity to earn increased profits. These costs are every bite as real as the payment of dollars out-of-pocket.
This notion _______ opportunity cost can be reinforced _________ a famous saying ______ Benjamin Franklin, no slouch himself _________ operations management. To make the point, however, we must make a brief excursion into logic. One truth of logic is the validity of the so-called contrapositive, which says simply that if the statement “If A, then B” is true, then it is also true that “If not B, then not A.” That is, of every time A occurs B follows, then we can be sure that if B does not occur, then A did not occur as well. Enough logic then, and back to Ben Franklin.
One of his Poor Richard sayings is that “A penny saved is a penny earned.” We have all recognized the truth of that since childhood, but I assert that by this saying Ben showed us he knows everything about opportunity cost. After all, what is the contrapositive of “A penny not earned is a penny not saved (i.e., a penny sent). All we are saying by this notion of opportunity cost is that “a penny not earned (an opportunity forgone) is a penny spent.” We shall often have occasion to consider opportunity costs, in analyzing and deciding various operations issues.

1. The word ‘himself’ underlined in the text, is being used in the sentence as a reflexive pronoun. 2. The negative form of: ‘This phenomenon goes by the name of ‘opportunity cost,...’, is: ‘This phenomenon doesn’t go by the name of ‘opportunity cost,…’ 3. The words in bold in the text are examples of irregular verbs. 4. The word ‘however’ in: ‘To make the point, however, we must make a brief excursion into logic.’ is being used as a contrastive connector

What is Distance Learning and Why Is It So Important?
Your gut, your emotions
What controls our emotions? The same two people might see the same tragic newspaper headline, (1) __________ one is much more emotionally affected than the other. Why is that? According to an international team led by UCLA researchers, these emotions may be partially driven by an unlikely source: our gut bacteria. In fact, the bacteria that colonize our intestines may influence the architecture of the brain itself.
The experiment examining the relationship between brain development and the gut microbiome was conducted with mice. Specific strains of mice, one that lacked a complete gut microbiome and one that had a normal microbiome, were compared in terms of their brain development and behavior. The influence of microorganisms is not limited to brain development.
Interestingly, the mice with the ―normal‖ microbiome had more anxiety and moved less than the mice without the microbiome. (2) __________ exposed to a microbiome early in life, the active, calm mice began to act more anxious and reduced their movements. Microbiota evidently had this influence by affecting hormonal expression and building particular pathways in the brain associated with anxiety. The influence on brain development apparently occurred at a particular point early in the mouse‘s life, so it‘s possible early exposure to a proper microbiome is important for normal development. The researchers speculate that the microbiome helps the mice develop an appropriate sense of caution.
The influence of microorganisms is not limited to brain development. (3) __________ no conclusive link has been established, a few studies have detected abnormalities in the gut microbiomes of children with Autism Spectrum Disorders compared to non-affected children. Nor is microorganism influence limited to gut bacteria. A separate study in hyenas (also awaiting conclusive proof) suggests that individual hyenas use a specific cocktail of stinky bacteria in their scent markers left as a message to other hyenas.
(4) __________ some fungus can get in on the act, hijacking ants and forcing the unfortunate insects to relocate to a place favorable for a fungus to grow. The ant does not survive, but it makes great fungus food. (5) __________ a growing body of evidence from other animals, until the UCLA study there was not much direct research on how the microbiome affects humans. But given its potential importance, hopefully there will soon be more research along these lines. Going with your gut, indeed!
