Spitting Image: Controlling Pain with Your Brain

April 29, 2004

Controlling Pain with Your Brain

Biofeedback techniques based on electroencephalogram (EEG) recordings of brainwave patterns, in which electrodes are placed on the scalp, are used with some success to treat epilepsy and attention problems such as ADHD.

Now Fumiko Maeda, Christopher deCharms and their colleagues at Stanford University in California have tried showing people real-time feedback from a functional magnetic resonance imaging (fMRI) scanner...

---Are they factoring in the effect MR (magnetic resonance) might be having on the brain? 39 minutes with your head in a fMRI scanner might itself account for any new sensations. However according to this page: "there have been no documented significant side effects of the magnetic fields and radio waves used on the human body to date." but "because the effects of strong magnetic fields on a fetus are not well documented at this time, pregnant women are usually advised to avoid MRI scans."
I wonder if someone will soon be selling a personal fMRI? Think of the fun you can have as you watch the colors, i.e. areas, of your brain react to various stimuli in the privacy of your room. Forget tattoos and body modifications, punching holes, scarring, sticking metal on or under your skin. With fMRI you can watch in real time while you train your brain. Documenting as you go do-it-yourself brain modification.
Biofeedback your way to orgasms without physical stimuli? To what your brain was like when you were say 20 years old? Your first encounter with ice cream; your favorite painting; recording; long dead friend or relative? Strange Days?

use; mighty Durbanu before whom we would kneel in supplication (with purely-
for-defense bombs hidden in our pockets) with lowered heads (making invisible
the knife in our teeth) and ask for crumbs from their table (in order to
extrapolate the location of their kitchens).

So she went into the garden to cut a cabbage leaf to make an apple pie;

into the shop. "What! no soap?" So he died, and she very imprudently

This is clearly another case of too many mad scientists, and not enough

buy cialis cheap cialisThe reported resort to astrology in the White House has occasioned much
merriment. It is not funny. Astrological gibberish, which means astrology
generally, has no place in a newspaper, let alone government. Unlike comics,
which are part of a newspaper's harmless pleasure and make no truth claims,
astrology is a fraud. The idea that it gets a hearing in government is
dismaying.
