Learning about learning

Remember those photos from Aspen? Here’s a post for the Dana Foundation blog on what I was doing there, work-wise:

How does school work, brain-wise? Do children teach themselves or is it something about the instruction that gets their brains firing and wiring faster? Last fall, a few hundred neuroscientists, teachers, and curriculum-makers met for a weekend to hash out what we know about learning and how we could use it to help every child succeed at school. One early answer: Play. 

The Aspen Brain Forum was sponsored by the New York Academy of Sciences, which has posted an extensive summary of the event as well as slides and audio from eighteen of the sessions. For an introductory taste of the event, though, try the 18-min podcast (which we sponsored). Science and the City’s Nadja Popovich talked with three of the presenters, who sketch the growing field and describe a few surprising results.  

Many of these results are connected to the cognitive properties of executive function, especially attention: inhibiting distraction, focusing on the correct aspect of a task, and maintaining focus. For example, Adele Diamond of the University of British Columbia describes the “red-pencil technique” for children who are writing their letters or numbers the wrong way (mirrored). Asking them to remind themselves to stop before they have to write a “6″ and switch from their regular pencil to another one to write that number slows them down enough that they write the number correctly, a change that seems to last. Diamond also points out that learning programs that include social, emotional, and physical components (such as play) “are better for academic achievement and executive function” than those that focus solely on academics. “Addressing only the cognitive seems to be less beneficial,” she says.

On the subject of play, Daphne Bavalier of the University of Rochester offers tantalizing research into the benefits of often-denigrated video games. Studies done on undergraduate non-gamers who played games for the first time for a few dozen hours seem to show they have improved vision acuity and speed as well as attention. How might programmers tweak games to foster improvements that could last?

Bruce McCandliss of Vanderbilt University describes research that suggests that differences in learning abilities and styles may have a grounding in attention, tooor rather, what we focus our attention on. Brain scans of young people focusing on the beginnings and endings of spoken words differ in predictable ways from the scans of those who focus on the melody of the sentences, for example. Might “poor” readers be focusing on a less-helpful aspect of the language, perhaps enjoying the music of the language and missing its meaning? “Different learning styles may rely on different styles of attention,” he says, and might benefit from different methods of instruction.

Like most of neuroscience, questions are more plentiful than answers. We do know some things work better than others, though; Diamond cites the Montessori, Tools of the Mind, and Path curriculums; Jump Math also seems to be making mathematicians of entire classrooms, not just a lucky few, according to John Mighton (who was not on the podcast but did attend the meeting).

The main take-away? Everyone learns a little differently, so relax about it. As Diamond says, “stress impairs executive function.”

Launch of pattern books

Came across this today while doing unrelated research:

From the London Times, 7 January 1809, page 3

ACKERMANN’S Repository of Arts, &c. which has just appeared, has adopted a novelty, we are surprised not to have been long since thought of, that of making a periodical publication the vehicle to distribute patterns of different articles of British manufacture that unite fashion, elegance, and utility.

Brainy days

Whew, we’re done with a week of meeting smart folks and learning about the brain. More than 31,000 neuroscientists hit DC last week, and a lot of us wrote about it. Here are my entries for The Dana Foundation:

How Do You Get Involved in Neuroethics?
During a workshop at the annual meeting of the International Neuroethics Society, panelists advised ethical wannabes to just get started.

Sex (differences) and Brain Science
Is the study of sex differences gaining traction in neuroscience? It was the topic of the very first Social Issues Roundtable at the Society for Neuroscience, in 1983, and it was the topic again this year.

Generating Obesity
The obesity epidemic was the topic of the Public Advocacy Forum at the Society for Neuroscience annual meeting on Wednesday, and it was nearly two hours of scary data with a little bit of hope.

New vocabulary

Brain scientists occupy DC

Smack in the middle of National Novel Writing Month, I have to switch gears for a week to report on the news in brain science (that’s my day-job). Neuroscience 2011 is the big event of the year for these folks. Starting Saturday, more than 30,000 scientists from around the world are expected to converge on the Walter E. Washington Convention Center in Washington, DC, to present and discuss cutting-edge research on the brain and nervous system.

This is my sixth time attending (as a member of the press, not a brain expert), and I love to soak up the enthusiasm and cheerful argumentitiveness of these passionate folks. And boy, do I learn a lot. The event is organized by the people at the Society for Neuroscience (SfN), whom we work with on many projects, especially Brain Awareness Week (BAW). On Saturday, we’ll be presenting during the Brain Awareness campaign meeting, at 3 pm in the Convention Center’s Room 151.

There is always a ton of new research at the conference; some of it is incremental or not-yet-ready-for-publication, but don’t be surprised if you see a lot of news stories on brain topics this weekend.

At the Dana Foundation blog, we’ll be reporting from the event over the next few weeks, but if you want to follow an up-to-the-minute feed hop onto Twitter: The official conference hashtag is #sfn11. Nature is planning a lot of coverage, starting at its blog Action Potential and via Google+. If you’re interested in specific topics, you might follow one of SfN’s official neurobloggers, who are focusing on various themes, from nervous-system disorders to history and teaching.

I attended one of the auxiliary events already, on Thursday and Friday, the annual meeting of the International Neuroethics Society. My story, “How do you get a job in neuroethics?” is up, at dana.org.

Where do you get your ideas?

As part of my prep for National Novel Writing Month (nanowrimo.org), which starts next week (eek!), I’m reading through issues of the London Times from 1808. My story this time will be that of a British journalist sent to Spain to cover the start of the campaign there against the French. Amongst the reports on the Spanish war and the lifting of the tax on coffee, I found this item:

SUICIDE.—A beautiful young woman, who was recently the adored of a certain Marquis, and who has since been under the protection of a military officer, put a period to her existence at her apartments, a draper’s, in Oxford-street, on Sunday night, by taking a considerable portion of laudanum. Her last protector had dined and spent the day with her on Sunday, and after his departure, at 11 o’clock at night, the lady was found in tears, and much dejected. She was found dead in her bed at nine o’clock on Monday morning, and it was ascertained, that she had taken a tea-cup full of the poisionous liquid.

(The Times, 8 October 1808, p. 3)

Uh-oh. I feel another story coming on.

The Blasted Brain

[by me for the Dana Foundation blog. See more great stuff there!]

Traumatic brain injury (TBI), the signature injury of the current U.S. wars, calls for the nation’s best “emergency medicine,” Kevin Kit Parker told a group of top scientists, medicine makers, and policy makers, this spring at the One Mind for Research conference in Boston.

“Certainly TBI, as it affects the force, is a national security issue, and it’s certainly an emergency issue.” Like the race to the moon and the Manhattan project, he said, TBI is an emergency science project with national security at stake and a need to move rapidly.

“You’ve got young NCOs [non-commissioned officers], young soldiers out there that have been blown up a dozen times, a dozen times they’ve suffered a traumatic brain injury, since 9/11. We have this growing cadre of our professional warriors that are out there, that are walking around, and the concern is, what does the future hold for them?”

The timelines of TBI damage range from nanoseconds to years. “The data now is pretty clear that TBI can potentiate a variety of neurodegenerative diseases, including Parkinson’s and Alzheimer’s disease,” Parker said. “So the outlook for these young soldiers is kind of bleak right now.”

Parker, a professor at Harvard, has also served multiple tours in Afghanistan in the Army Reserve, tending the wounded immediately after impact and observing their recovery on base and back in the United States. The experiences led him to expand his research focus from the physics of the heart to the brain. “When people started trying to kill me with IED’s I thought I’d better get a piece of this,” he said.

His background also led to an unusual approach to the problem, or at least unusual for neuroscientists. “I’m an infantry officer in the reserve, and I’m not a physician, I’m a physicist, so I look at things in terms of scaling laws.” Interested in how mechanical energy (such as from blasts) affects neurons, he and the people in his lab decided to try to build physical models of blast injury from molecule to cell and from cell to tissue.

“We use tissue engineering as a tool, including blasting neurons,” he said. “What we found right away is that we can mimic some of the things that the neuropathologists are reporting that they’re seeing in patients.”

“Now that we’ve got all these models, we’re working on developing a systematic understanding of the mechanical forces required to injure these neurons, these vascular tissues, and understand the chemical cascades that are turned on by these mechanical forces.” If they understand these chemical cascades, they could start to identify which molecules along the cascade are the most vulnerable—and which might be easily reached by drugs and other therapies.

Part of emergency medicine is exploring many avenues simultaneously, Parker said. His theory is it’s diffused axonal injury that leads to damage from TBI, but researchers need to work on multiple hypotheses, to “flank the problem” with the outside-the-box ideas until someone finds some badly needed solutions.

One giant challenge: “We need to build a brain,” he said. “Everyone would benefit from having a brain in their [laboratory] dish to work on:” a 1 mm3 piece of brain that mimics the neural microenvironment, scalable so what people discover in the lab can be tested in drug-maker’s wide-assay studies. He’s working on it.

In addition, “we need to push the science as far forward [on the battlefield] as we possibly can,” he said. “It might be a diffusion tensor imager that we put downrange, it might be a biomarkers lab that we put downrange … so we can understand, as these soldiers come off the battlefield, what’s happening to them, rather than waiting 6 months, 12 months before they present at a VA emergency room.”

“The whole idea is that when these guys [medics] run up there to pull these broken kids out of this MRAP [armored vehicle], that there’s a whole team behind them supporting them,” he said. “If I run up there and this kid’s got a leg dangling off, I know how to apply a tourniquet to him. If I run up there and he’s got his bell rung, I got no way of treating this guy right now. And right now he’s at the genesis of these neurodegenerative diseases that might not appear for 20-30 years down the road.”

His remarks start just after minute 1 of this video. The slides he uses are especially useful in understanding the science.

The forum was held in Boston May 23–25 by the One Mind for Research campaign, whose goal is “to significantly reduce the U.S. burden of disability due to brain disorders.” The campaigners released a blueprint of research goals at the event: “A Ten-Year Plan for Neuroscience: From Molecules to Brain Health” (PDF). Videos of all the sessions are collected on the Science Network site.

The Science Network also did a wide-ranging interview with Parker, on work in the lab, his experience in Afghanistan, how he got started in science, and his passionate advocacy for his compatriots in the field. (22 min). It’s also well worth a listen.

More Aspen!


Best part of hiking the park trails in town is all the “hidden” art along the paths. Plus, on a Monday, almost nobody was on the trails! It is easy to meditate in Aspen.



One kind soul did wander by so I could ask him to take my picture. He was one of the few on the trail who did not have a giant (but well-behaved) dog. I saw one big Jeepish car with 3 big dogs in the back seat, hanging their heads out the windows, and another big dog doing the same from the passenger seat.

Crocs enjoy the view from my back porch at the Hotel Aspen. Sadly, crocs are not in style in Aspen — it’s flip-flops, duh. So many women out at night in fall outfits, wrapped in jackets and thick scarves, and flip-flops on their feet.
