CTF MEG™ Magnetoencephalography Brain Imaging System

Filed under: Neurology , Radiology

O'Canada-based VSM MedTech Ltd. reports that its magnetoencephalography (MEG) functional brain imaging system will be installed at the Center for Neuromagnetism at NYU Medical Center. The 275-channel CTF MEG™ device is scheduled to be in place in 2006.

The company describes its technology:

Magnetoencephalography (MEG) is a revolutionary medical imaging technology that provides unprecedented insight into the workings of the human brain through the measurement of electromagnetic activity.

By measuring the magnetic fields created by the electric current flowing within the neurons, MEG identifies brain activity associated with various human functions in real time, with millimeter spatial accuracy.

This non-invasive approach can positively impact patient outcomes, providing clinicians with the invaluable information they need to evaluate neurological disorders and plan surgical treatments.

Our CTF MEG systems are the most technologically advanced instruments available in the world today, offering MEG sensor arrays of up to 275 distinct channels with up to 128 simultaneous EEG sensors. The exquisite sensitivity of the MEG sensors is achieved by utilizing the world's most sensitive detectors of magnetic fields, SQUIDS (Superconducting Quantum Interference Devices)...

How does MEG work?

Both spontaneous brain function (for example, normal alpha waves or pathological epileptic spikes) and evoked brain activity (caused by an external stimulus such as visual, auditory or tactile input) can be measured using MEG. In both cases, electrical currents in a group of neurons within the brain create very small magnetic fields. Special detectors called superconducting quantum interference devices (SQUIDs), cooled to the temperature of liquid helium (about -273°C), can measure these tiny magnetic fields.



 Approximately 10,000 neurons firing in concert are non-invasively detectable by MEG

With sophisticated electronics and software, the output of the SQUIDS are used to localize the source of the brain activity within millimetres. The resulting functional brain data may then be overlaid on an anatomical image produced by, for example, an MRI.

The company says that this diagnostic modality can be used for patients in preparation for neurosurgery as well as in treatment of epilepsy. It also "holds promise for millions of patients suffering from a wide range of debilitating neurological disorders."

The original article kind of shows the author doesn't really know much about the e-meter, and may very well have never seen one himself.

You can easily check the information below by simply trying it yourself. Go to the nearest church of scientology and ask them to try. They won't bite. That way you will be able to decide for yourself what's what and how it works.

1. Correct. An e-meter cures nothing. Like, say, a CAT scan. The CAT scan gets you pictures and data, but all by itself, it cures absolutely nothing. An e-meter will not cure anyone or do anything beyond providing measures of minute electrical changes. Those measures are extremely precise and can be used by a trained practitionner to help a person locate and erase painful emotions and thoughts.

2. Yes, an e-meter reacts when you squeeze or release the cans. This is what we call a "body motion read". (a read is a motion of the needle, falling on one side). A body motion read is caracterized by a delay.

Meaning if you squeeze or release the cans, the needle will move about one second later.

However, if you think of something, the needle will move *instantly*. no delay there.

A properly trained person will be able to make the difference between the meaningless body motion reads and reads caused by thought.

Anyone can observe the difference during a test. It take quite a bit of training however to use it to help someone else.

If you want to check the data above, you don't need to be an expert. Just go to a church of scientology and ask them to do a test to see how the e-meter works.

That will not make you an expert, or something, but at least you will see for yourself what that machine can do. A machine that can track your thoughts. Guess it's worth checking out if it really works or not.

NB: It doesn't detect lies. It detects emotions and thoughts.

I hope this will help you understand a little better what you are talking about, but bottom line is that you don't have to believe me. Just give it a try and figure it out for yourself..

Yes, you can try the e-meter yourself at the local org...or you can stop at one of many tables Scientology sets up to try to recruit new members. Take a "Stress Test" with the e-meter! Come one, come all!

How do you justify using a "religious artifact" such as an e-meter for something as frivoulous as a stress test? Especially because each e-meter (and every single publication put out by Scientology) must contain this Federally mandated paragragh:

HUBBARD ELECTROMETER MANUFACTURING

"By itself, this meter does nothing. It is solely for the guide of Ministers of the Church in Confessionals and pastoral counselling. The Electrometer is not medically or scientifically capable of improving the health or bodily function of anyone and is for religious use by students and Ministers of the Church of Scientology only. HUBBARD, E-METER and SCIENTOLOGY are trademarks and service marks owned by RTC and used with its permission."

Funny though - the author of this piece never interviewed a single Scientologist. If I were to write a piece about the Cello, I might think of asking a cellist how the instrument is played. Were I to write about computers, I might ask a computer guy how they´re put together and how they run.

E-meters are used by Scientologists. Writing a piece and not deigning to ask one of the millions of Scientologists a single question is poignantly obtuse.

Greg,

The E-meter is described by Scientologists as basically a medical device. Yes there are legal ramifications that make Scientologists provide some small print that states otherwise, but a layman wouldn't know that.
So, this being touted as a medical device, we asked our staff doctors and they wrote what they thought. Seems to me that a medical journal should be talking to doctors about medical devices. Talking to a Scientologist will get you propaganda, not a medical opinion, even though it might sound like a medical opinion. We don't talk to Scientologists about this just like we don't talk to Christian Scientists or the Amish about their medical views, because they are effectively irrelevant to a scientific discussion.
And as far as your general point about having to talk to a specialist, you can, for example, learn about electricity without asking an electrician. You can learn how a car works without talking to a mechanic. And just the same, the E-meter is just a device, the properties of which can be effectively described without needing to be a Scientology priest..
And if you are a Scientologist, why don't you comment on what you think our errors were, instead of criticizing our methods?

About the comments on TV regarding pain medicine and silence during delivery, where I come from, women give birth without pain medicine and not make a sound during delivery all the time. I don't know how it relates to scientology but we call it 'Pohnpeian Pride' and it's everything that makes you a woman.

"Katie, it happens everyday, and it's what makes you a real woman!!!!!"

The commets on the TV that says "it's impossible not to make a sound during delivery" is not TRUE, it happens everyday in my small country called 'Micronesia or Federated States of Micronesia'.

No shit, Rose David! Some of the highest levels of obesity in the world is in Micronesia. So it is no surprize that 300lb+ women don't make a peep.

Any input from Samoans on this one?

Bruder,

You say:
" And if you are a Scientologist, why don't you comment on what you think our errors were, instead of criticizing our methods?"

You were addressing Greg, but you somewhat ignored my comments, which did precisely that. You did not however answer on those, nor did you correct the mistakes I point out.

Greg's remarks were valid about your methods. In the article, you make a couple of assumptions on what "scientologists feel". That would require asking a scientologist, wouldn't it?

And about the little "science" thing, well, sorry but real scientific research doesn't not mean "asking experts for their opinions". In *real* scientific research, you run tests. You try the machine yourself, and observe how it works and what it does.

That's what scientific research is about. Testing. Looking. Running experiences. Not asking "experts" for their opinion.

The e-meter is *not* a medical device, and a medical doctor will not, in the course of his medical training, learn anything about it.

He may at best tell you a bit about lies detectors (very crude machines). But those compare to the e-meter like a magnifier compares to an electron microscope.

Why not simply go and test an actual e-meter? Your medical experts probably haven't done so either, so grab them along and just run some experiment with it.

We don't ask you to take anything on faith. We ask you to look instead of always listening to people who haven't looked either. Get first hand knowledge, then tell your readers about what you know. Real research takes more time, but well, as a writer, that's your job.

Sylvain Galibert,

For the record, I just contacted the Church of Scientology of New York to ask whether we can try out the e-meter. I was told that because it is a "religous artifact", they will not grant us access to it. So, Sylvain, it looks like claims can be made but not confirmed by outsiders. Basically, I followed your advice and it didn't help resolve this dilemma. So, if you can help organizing a demonstration of the e-meter, we will gladly check it out. But at this point, we'll have to remain sceptical.
