Think Away the Pain

Pain can be mysterious, untreatable and debilitating, and its causes can be unknown. But if you could see the pain -- or, at least, your brain's reaction to it -- you might be able to master it.

A study from researchers at Stanford University and MRI technology company Omneuron suggests that's possible, and the results could lead to better therapies for those suffering from crippling chronic pain.

The researchers asked people in pain to try to control a pain-regulating region of the brain by watching activity in that area from inside a real-time functional magnetic resonance imaging, or fMRI, machine. Initial results showed subjects could reduce their pain, some quite dramatically.

It's the first evidence that humans can take control of a specific region of the brain, and thereby decrease pain, said Stanford professor Sean Mackey, who co-wrote the paper, which was published last week in Proceedings of the National Academy of Sciences.

"(Similar to) going to a gym and working muscle using weights, here we're using the real-time fMRI technology to exercise a certain brain region," he said.

Study co-leader and Omneuron CEO Christopher deCharms said for many people with chronic pain, available treatments like medication or surgery simply don't work. But this exercise, which researchers have termed "neuroimaging therapy," could one day help some of the millions of Americans who suffer from untreatable chronic pain.

In the study, eight healthy subjects who'd been subjected to a painful stimulus and eight chronic pain patients underwent a series of fMRIs. The images tracked activity in the brain's rostral anterior cingulate cortex -- an area deCharms said is related to pain. Subjects watched this area on a monitor in real time during the procedure. Prompted by researchers' suggestions of trying to lessen their own pain by ignoring it or imagining it as benign, they set out in a mental game of hot-and-cold to lessen their discomfort.

Twenty-eight healthy subjects and four pain patients were also put into control groups that tried to control pain by viewing other patients' brain data or using other mental strategies, but no fMRIs. These tactics didn't show a significant reduction in pain, deCharms said.

The pain patients reported that the fMRI helped them decrease their overall pain 64 percent. Healthy subjects said they saw a 23 percent increase in their ability to control the strength of their pain, and a 38 percent increase in their ability to master its unpleasantness.

"I think most people found it very exciting to be able to watch the activity in their own brain, moment by moment, as it took place," deCharms said.

Vera A. Gonzales, a pain psychologist in League City, Texas, said she thinks the study lends scientific data to what scientists already knew empirically -- that people can decrease their own pain by focusing on certain thoughts.

It probably also helped that subjects could watch their brain activity unfold on a screen, she said. For years, some therapy methods have allowed patients to monitor and try to control their biofeedback by concentrating on things like skin temperature and heart rate.

Mackey and deCharms cautioned it will be some time before such therapy could be available for commercial use. They're investigating the process of getting Food and Drug Administration approval, and right now they're focusing on a study to investigate the effects of long-term neuroimaging therapy, deCharms said. One day, patients may even be able to think away other problems like depression, anxiety and dyslexia.

"We don't yet have a good answer to what happens if you keep practicing and practicing," he said.

you should read some of the scientific studies on mediation, man...

It has taken quite a bit of time for people to be able to get this info. out of a source that doesn't try to sell you crystals, "spiritual advice" via phone, dreamcatchers or tarot cards. Wired?...interesting.

see, this:

wired is TRYING to seel you communication with presences you have never met (internet and compute advetisements), a tenchnical apllication of non-physical contact - the tenet of spiritism. & crystals were monitoring and data reception gear,.. i.e. computers. (especially in relation to silicon)

and i happen to have a formal education in Tarot, that may astound those who even offer to sell their wares.

Tarot is a very complex set of simple symbols...

or maybe vice versa.

You think that's air you're breathing..?

Buddha on the Brain
The hot new frontier of neuroscience: meditation! (Just ask the Dalai Lama.)
By John GeirlandPage 1 of 2

The Dalai Lama has a cold. He has been hacking and sniffling his way around Washington, DC, for three days, calling on President Bush and Condoleezza Rice and visiting the Booker T. Washington Public Charter School for Technical Arts. Now he's onstage at the Washington Convention Center, preparing to address 14,000 attendees at the Society for Neuroscience's annual conference.

The mood is tense. The State Department Diplomatic Security Service has swept the hallways for explosives. Agents stand at their posts.

The 14th incarnation of the Living Buddha of Compassion approaches the podium, clears his throat, and blows his nose loudly. "So now I am releasing my stress," he says. The audience dissolves into laughter.

The Dalai Lama is here to give a speech titled "The Neuroscience of Meditation." Over the past few years, he has supplied about a dozen Tibetan Buddhist monks to Richard Davidson, a prominent neuroscience professor at the University of Wisconsin-Madison. Davidson's research created a stir among brain scientists when his results suggested that, in the course of meditating for tens of thousands of hours, the monks had actually altered the structure and function of their brains. The professor thought the Dalai Lama would make an interesting guest speaker at the Society for Neuroscience's annual meeting, and the program committee jumped at the chance. The speech also gives the Tibetan leader an opportunity to promote one of his cherished goals: an alliance between Buddhism and science.

But the invitation has sparked a noisy row within the neuroscience community. To protest the talk, some scientists set up an online petition, which was immediately hacked by the pro-Dalai Lama faction. Others are boycotting the event or withholding their conference papers. Still others have demanded - unsuccessfully - time for a rebuttal.

All of which may explain the lama's ailment. "His Holiness' cold is a manifestation of the opposition of some scientists to his coming to the conference," a young Chinese Buddhist explains to me.

The protesters complain that the Tibetan leader isn't qualified to speak about brain science. They fret that he'll draw media attention away from important findings presented at the conference. Worst of all, his presence muddles the distinction between objective inquiry and faith. "We don't want to mix science and religion in our children's classrooms," says Bai Lu, a researcher at the National Institutes of Health, "and we don't want it at a scientific meeting."

Thank you for that article...

Seems to me, that the best way to study the brain would be introspectively, and through meditation...Shit, we've looked at it objectively for so long, and pretty much don't know shit about how it works in conjuction, or as the mind...Interesting that they would oppose another world leader speaking about any subject, if for nothing along exposure to a culture would be nice...

All I know is that if I have a headache or some other semi-chronic pain and meditate and do my relaxation routines... I feel MUCH better. Of course, Darvocet works pretty good too. LOL
