In Lowell, Massachusetts, a group of energetic teens are pushing a proposal to lower the voting age to 17 for local elections. They have their own Facebook page (Vote17) and have gotten national media attention from Fox:

‘Vote 17? movement pushing for teen voice in local elections, Fox News, July 11, 2012

In this age of voter apathy, a group of teenagers in one of Massachusetts’ oldest Mill towns is fighting for the right to weigh-in on city business and cast ballots before they turn 18. The ‘Vote 17? movement looks like a well-organized campaign, with office space in downtown Lowell where the teens involved spent Tuesday morning creating information packets and prepping for a trip to the state capitol — where they’re trying to get state lawmakers to support their cause.

Carline Kirksey just graduated from Lowell High School. She’s heading off to college in the fall but remains passionate about ensuring the next generation of classmates will get a say when it comes to school and City Council elections.

“I feel like if we were able to vote at 17 we’d be able to create civic habits and increase engagement and increase voter turnout and increase youth voices in Lowell and a lot of the youth in Lowell are really engaged,” said Kirksey from the organization’s busy office. “We just come here every day and shoot emails to the representatives, senators and make sure we get to talk to them about why we want this to happen.” [. . .]

Back in the real world, brain science has informed us that the teen brain is a work in progress, to be kind. The brain isn’t fully mature until the mid-twenties, according to recent research.

If anything, the voting age should be raised to 25. Allowing emotion-propelled children to vote just because they want to is not the way to go. Our civic life needs more educated voters, not the unfocused brains of immature teens.

In addition, lowering the voting age would benefit liberal candidates and causes because many schools are little indoctrination factories, spewing left-wing ideas like open borders. As generally happens, life teaches more conservative values, so older voters are wiser in the ways of the world and how diversity decreases trust, among other aspects of human nature.

In 2002 PBS’ Nova presented a program titled Inside the Teenage Brain. You can watch the episode at the website, but be forewarned, the show is full of snotty kids in complaint mode as they have their brains tested. One point is that MRI scans show teen brains work differently than adult brains.

A more recent report from NPR focused on how the connections in the frontal lobe have not become fully attached in the teen brain.

When adolescence hit Frances Jensen’s sons, she often found herself wondering, like all parents of teenagers, “What were you thinking?”

“It’s a resounding mantra of parents and teachers,” says Jensen, who’s a pediatric neurologist at Children’s Hospital in Boston.

Like when son number one, Andrew, turned 16, dyed his hair black with red stripes and went off to school wearing studded leather and platform shoes. And his grades went south.

“I watched my child morph into another being, and yet I knew deep down inside it was the same Andrew,” Jensen says. Suddenly her own children seemed like an alien species.

Jensen is a Harvard expert on epilepsy, not adolescent brain development. As she coped with her boys’ sour moods and their exasperating assumption that somebody else will pick up their dirty clothes, she decided to investigate what neuroscientists are discovering about teenagers’ brains that makes them behave that way.

Teenage Brains Are Different
She learned that that it’s not so much what teens are thinking — it’s how.

Jensen says scientists used to think human brain development was pretty complete by age 10. Or as she puts it, that “a teenage brain is just an adult brain with fewer miles on it.”

But it’s not. To begin with, she says, a crucial part of the brain — the frontal lobes — are not fully connected. Really. 

“It’s the part of the brain that says: ‘Is this a good idea? What is the consequence of this action?’ ” Jensen says. “It’s not that they don’t have a frontal lobe. And they can use it. But they’re going to access it more slowly.”

That’s because the nerve cells that connect teenagers’ frontal lobes with the rest of their brains are sluggish. Teenagers don’t have as much of the fatty coating called myelin, or “white matter,” that adults have in this area.

Think of it as insulation on an electrical wire. Nerves need myelin for nerve signals to flow freely. Spotty or thin myelin leads to inefficient communication between one part of the brain and another.

A Partially Connected Frontal Lobe
Jensen thinks this explains what was going on inside the brain of her younger son, Will, when he turned 16. Like Andrew, he’d been a good student, a straight arrow, with good grades and high SAT scores. But one morning on the way to school, he turned left in front of an oncoming vehicle. He and the other driver were OK, but there was serious damage to the car.

“It was, uh, totaled,” Will says. “Down and out. And it was about 10 minutes before morning assembly. So most of the school passed by my wrecked car with me standing next to it.”

“And lo and behold,” his mother adds, “who was the other driver? It was a 21-year-old — also probably not with a completely connected frontal lobe.” Recent studies show that neural insulation isn’t complete until the mid-20s.

This also may explain why teenagers often seem so maddeningly self-centered. “You think of them as these surly, rude, selfish people,” Jensen says. “Well, actually, that’s the developmental stage they’re at. They aren’t yet at that place where they’re thinking about — or capable, necessarily, of thinking about the effects of their behavior on other people. That requires insight.”

And insight requires — that’s right — a fully connected frontal lobe.

More Vulnerable To Addiction
But that’s not the only big difference in teenagers’ brains. Nature made the brains of children and adolescents excitable. Their brain chemistry is tuned to be responsive to everything in their environment. After all, that’s what makes kids learn so easily.

But this can work in ways that are not so good. Take alcohol, for example. Or nicotine, cannabis, cocaine, ecstasy …

“Addiction has been shown to be essentially a form of ‘learning,’ ” Jensen says. After all, if the brain is wired to form new connections in response to the environment, and potent psychoactive drugs suddenly enter that environment, those substances are “tapping into a much more robust habit-forming ability that adolescents have, compared to adults.”

So studies have shown that a teenager who smokes pot will still show cognitive deficits days later. An adult who smokes the same dose will return to cognitive baseline much faster.

This bit of knowledge came in handy in Jensen’s own household.

“Most parents, they’ll say, ‘Don’t drink, don’t do drugs,’” says Will, son number two. “And I’m the type of kid who’d say ‘why?’ ”

When Will asked why, his mom could give him chapter and verse on drugs and teen brains. So they would know, she says, “that if I smoke pot tonight and I have an exam in two days’ time, I’m going to do worse. It’s a fact.”

There were other advantages to having a neuroscientist mom, Will says. Like when he was tempted to pull an all-nighter.

“She would say, ‘read it tonight and then go to sleep,’” he says. “And what she explained to me is that it will take [what you`ve been reading] from your short-term memory and while you sleep you will consolidate it. And actually you will know it better in the morning than right before you went to sleep.”

It worked every time, he says.

It also worked for Andrew, the former Goth. He’s now a senior at Wesleyan University, majoring in physics.

“I think she’s great! I would not be where I am without her in my life!” Andrew says of his mom.

For any parent who has survived teenagers, there are no sweeter words.
