Your Momma Should Have Known
"Our brains develop according to a recipe encoded in our genes...The sequence of DNA in those genes is pretty much fixed. For experiences to produce long-term changes in how we behave, they must be somehow able to reach into our brains and alter how those genes work."
- Carl Zimmer
Nothing against your mother. The point is that your mother and everyone's mother should have been taught what you are about to learn, before you were born. The news is recent, but the information itself has been around since the beginning of our existence.
Caution: What you are about to learn may change what you think about life and how you understand the sometimes mysterious behaviour of others. You won't be asked to convert to any way of thinking. It will simply help you to understand.
Human behaviour, or human nature if you will, may present the greatest mystery and challenge anyone has ever faced. For examples, men ask "What do women want?" while women wonder "What makes men tick?" Neither is a huge mystery, it's just that we haven't taught each other what a few of us already know.
The study you will read about could not have been conducted on humans. At least not on living ones. You will soon understand why. It was conducted on rats. And on the brains of people who had recently died, some from suicide. Just to make it more enticing, love has a great deal to do with it.
In humans, love is a mystery. The word has more definitions than just about any other in the Oxford English Dictionary. The problem is that we can't get a handle on exactly what love is. Yet, in our own lives, we tend to quantify love. We don't measure love as such. We measure loving touch.
In general, we touch those we love more than those we don't love. When the romance of the early months of a new relationship filled with lots of loving touch fades and the touching reduces to little or nothing, we say that love was lost. People leave legal relationships seeking more and better love, but what they really seek is more loving touch. We tend to equate touch with love. We measure how much others love us by the amount they want to share loving touch with us.
Not so easy to test in a science lab. Especially when ethics intervenes when we want to prove that people change for the negative when they lack sufficient touch of others. Many labs have turned to rats as substitutes. The similarities between us and rats in these tests may make you uncomfortable, but they are real.
In one family of rats the mother was allowed to lick the fur of her babies, often and extensively. In another, the mother hardly licked her babies at all. As adults, the two groups of rats turn out very different. In the neglected group, the rats were easily startled by unexpected noises, they were reluctant to explore new places and their bodies produced lots of hormone when they experienced stress.
The licked and loved rats were not easily startled, showed great curiosity in exploring new places in their environment. And they "did not suffer surges of stress hormones," according to Carl Zimmer.
They did not suffer surges of stress hormones. I do. Like many others, I lack the gene that should cause my adrenal gland to produce a hormone that neutralizes the effects of epinephrin (commonly known as adrenalin), the chemical produced by the adrenal gland to prepare us for action in times of sudden stress, known as the fight or flight response. In other words, when my body senses stress, I not only get the surge of adrenalin but it hangs around in my bloodstream for hours, even for days.
Why do some people suffer severely from stress--even to the point of thinking about or actually committing suicide--while others seem able to handle stress with relative ease? The rats in the experiment above and in hundreds of other labs may show us the answer. The rats--and at least some of us--may not be able to handle stress as well as others because our brains and bodies are not prepared for what amounts to prolonged chemical warfare on us. Self-induced chemical warfare.
Two families of molecules control when our genes turn on and off, which ones and for how long. One, the methyl group, essentially plugs the path for genes to express themselves by producing proteins. The other, coiling proteins, wraps our DNA into spools so tight the genes can't become active. If either is too successful or lacking, something can happen with gene expression (or may be prevented from happening) that will affect our health and even our lives.
Our experiences can rewrite these two, collectively called the epigenetic code. Most of the writing or behaviour patterning is done before we are born. However, strong experiences after we are born--even extraordinarily strong experiences as adults--can rewrite the code.
Differences between the brain of the licked rats and the neglected ones were found in the hippocampus. The glucocorticoid receptor gene--the one that controls how long adrenalin stays in the bloodstream--for example, was capped off by methyl groups in the neglected rats and they had fewer receptors than the licked rats. Thus the neglected rats had fewer ways to stop adrenalin from doing its thing when it was no longer needed. They were permanently stressed out.
Neurobiologist Michael Meaney, of McGill University, and colleagues followed his rat studies by studying the brains of people who had recently died. Twelve had committed suicide and had suffered abuse as children, 12 had committed suicide but had not suffered abuse and the final 12 had died of natural causes. The suicide people who had suffered abuse had cortisol receptors capped by methyl groups and had fewer receptors, as they had found with the rats. Abuse in childhood had caused them to be permanently stressed as adults.
Another group studied suicide victims and people who died natural deaths and found methyl groups blocking the gene that produces the protein BDNF in the Wernicke area of the brains of the suicides. Environmental influences--everything after birth, including human interaction--can also affect adults.
Neuroscientist Eric Nestler, of Mount Sinai School of Medicine in New York City, examined the brains of mice that had been put through so much stress in conflicts with other mice that they were depressed. He found differences in an area of the brain called the nucleus accumbens, which is involved with the brain's reward system and helps to set values on things based on the pleasure derived from them. He found the DNA in that part wound tightly with coiling proteins. Nestler's group found the same kinds of epigenetic changes in the brains of depressed humans who had recently died.
Brain changes caused by coiling proteins and methyl groups should be able to be reversed, once we learn how. Nestler injected HDAC inhibitors into the nucleus accumbens parts of the brains of depressed mice to loosen the coils of DNA. Ten days later the mice were less hesitant about approaching other mice and other signs of depression were absent.
These studies suggest that previously intractable human troubles such as depression, suicide and a wide range of problems associated with constant stress (including those that impact the immune system) may be correctable. More study is needed and testing on humans will be tricky, maybe even risky at first.
Any change to the brain is risky. But it may be do-able. Medical science is still in the very early stages of learning about our most complex and sophisticated organ.
Soon taking a DNA sample of a newborn baby will be routine. The sample will be examined for variations from expected norms so the child can have a genetic adjustment made and avoid genetic problems and weaknesses that are an unfortunate part of life today.

How Public Schools Fail Us Tragically
How Public Schools Fail Us Tragically
"The social, emotional and spiritual are part of a child's connection with the world."
- Mary Paradis, director of development at the Vancouver Waldorf School
Why doesn't every child deserve the kind of education kids get at some private schools? The schools I refer to--Waldorf and Montessori are among them--teach the whole child, not just curriculum dictated facts and skills.
Children develop along four main streams: intellectual, physical, emotional and social. Mainline school systems address the intellectual and physical needs of their children, but curriculum seldom leaves time or room for social or emotional/psychological development. At that, intellectual development follows strict guides and physical development varies hugely from school to school and among various districts.
What would those strict guides be that schools follow? Education systems, in general, are designed to produce future employees who can do the jobs that big employers such as industries need to be done. And they produce consumers who will buy, use, throw away, then buy more of the products those industries manufacture.
Schools produce employees and consumers. The evidence is so glaring that those who argue against the claim have difficulty finding evidence of support. In fact, those who argue that schools are not designed to produce employees and consumers of the future delude themselves and try to persuade others so they don't feel so alone. If you doubt, just look at what topics fill school curricula and the young adults the schools produce.
Ironically, many of the leaders of the industries that employ public school system graduates themselves attended private schools. Is this true irony? In fact, no. Private schools, in general, prepare children to be leaders in their communities, not followers as public school systems do.
Providing "the right thing at the right time" in a child's learning development is the key to teaching to the whole child, according to Ryan Lindsay, president of The Waldorf Association of Ontario. Public schools, on the other hand, provide indoctrination of facts and skills in the employee-consumer model at the time most child have the ability to manage them. Those who are not ready fail--emotionally, if not by repeating school years--drop out when they reach the minimum age, often believing that they are too dumb for school. They try to work for large companies so they can depend on a steady income.
"We make sure we focus on teaching children how to think and not what to think," according to Lindsay. "We like to think we are laying the foundation in a more thorough way so that when children get to a certain age the approach aids their intellectual development."
Casting aside the lack of expertise you may feel regarding the topic of education as a whole, if you attended a public school do Mr. Lindsay's statements ring a bell about how you were taught? From what you know of adults today, do they know how to think, not just what to think when they make purchases?
We must keep in mind that private schools have the same number of teaching hours in their days as public schools. They don't have eight-day school weeks. Private school students are in class roughly the same number of hours as public school students the same age. Sometimes less if they have special assignments that take them outside the classroom.
What's the difference?
Some may claim that public schools have many more problem children to deal with than private schools. From my personal experience as an educator, I can see that argument having some merit. I also know that classes I taught in public schools had far fewer "problem children" than many of the other classes in the same schools.
In my teaching years in public schools, it was the teacher in my classes who kept getting into trouble, not the students. In my case I kept wanting to deliver to my kids what they needed and wanted and were desperate to take in and develop, not just what was on the curriculum. I believe my mission was to grow whole people, not just adults who were ready to be employees and consumers. I did. Administration often objected.
In general, classes with "problem children" do little to address their emotional and social needs. Consequently their problems tend to be emotional or social in nature--bullying, depression, fighting, shyness and so on. Where children have intellectual development problems--slow learners--very often the slowness of intellectual development relates back to emotional or social problems of the past.
And often to emotional or social problems of the present. How efficiently can we expect a child to learn if he or she has problems with a drunk or abusive parent at home, with a classmate or neighbourhood child who bullies them to and from school or on the bus, with a parent who does not provide a home atmosphere that supports what is taught at school, or even with the results of a recently broken close friendship?
For a child, emotional and social problems always take precedence over intellectual challenges in school. Always. It's how we are built. Emotional and social problems are related to our individual ability--our basic instinct--to survive. For our ancient prehistoric ancestors, intellectual development and learning took place when survival and personal safety and comfort were not at stake.
Most private schools address the social and emotional needs of their students. "I could never say enough good things about the value of community in a school," says Karen Murton, principal of Branksome Hall, a private school for girls in Toronto.
If a child can't get enough help with social or emotional development at home and his school doesn't have the time or the authority in its curriculum to address these needs, where does he get it, where does he turn to fill in the blanks he knows inherently he must fill? Television. Movies. Video games. Rumours picked up in casual conversations with peers. "Information" gleaned from overheard adult conversations behind closed doors and at parties.
Please consider that list carefully. Your child, or at least many of the children in your community, derive most of the emotional and social development information they receive from these same sources. Are they the sources you want young people to take as models? Think about their content.
Public schools could provide factual input, but most don't. They have the same amount of time with their students as private schools, but public schools spend their non-curriculum time dealing with created problems rather than teaching what the kids need to know to prevent them from happening.
One kind of school deals with kids who may already be broken. Another teaches what kids need to avoid breaking.
As astonishing as it may sound, addressing the emotional and social needs of children would not be a costly change for public schools. Most teachers already know this stuff and just need some direction, guidance and the authority to teach it.
If private schools can grow men and women who can lead major industries, professions and governments, public schools should easily be able to grow men and women who can think for themselves, who are more than mere automaton employees and consumers who work and buy as they are told.
If you believe what you have just read, then your family, your community, your world needs you to speak up about it. Only by speaking up will you find how many others think like you so that we can all work together to make life better for the future.
If we don't talk about this, we leave industries to manipulate their way into the lives of every student of every public school.
That's simply not acceptable.
