This new weblink I have, to here, is less forgiving than one I had before
new year.
Yesterday there was olde posts with respect to electrical activity vs.
magnetic fields and brain waves etc.
Most of us here may not be qualified to respond to reports that might be
better Peer-Reviewed by people who work in the field, than just dropping them
onto us, unless there is some author (poster)-added comments to prompt
discussion or ask what others might think.
I just got back to read it (the detail), and found several errors I wanted
to qualify comments on that post.
At one point they talked about an EEG measuring **ElectroMagnetic Activity
in the brain. An Electro Encephalogram measures Electrical signals generated
by parts of the brain as result of various stimuli during the test. It's Not
to measure Magnetic waves-- I think that's mostly done with an MRI (Magnetic
Resonance Imager) that produces a 3D Image as result of Magnetic impulses it
picks up to provide a picture of where Strokes, Damage or other insults
occured that might be causing (among other things), Seizures.
**This part, I'm not a Neuro, so don't know 1 way from the other, but it
sounds incorrect fwiw --> They said that All Neurons generate an Electric
Field ( "called the Electromagnetic Field" , they said ) that is then
measured by an EEG. Technically an Electric Field is not interchangeable with
the term Magnetic Field-- an Electric field can *Produce a magnetic field
depending on the carrier of the current (as in an MRI but also in other
science instruments which use electicity to generate magnetic fields: for
example, astronomy, atomic energy, and other uses).
At least one of the articles referenced, or in the description leading up
to its reference, implied that seizures were interchangeably an Electric **or
a Magnetic disturbance, within the brain, as though the 2 were equivalent
(equal) at the neuron level. Unfortunately, in at least 1 of the 3?
articles, since they started in the first 2 lines to suggest that the 2 were
'the same', then ran on about neurons doing this and that and magnetic
interference causing seizures etc. etc. ended up **Way out in Left Field,
leaving out people who might have seizures as result of Strokes, Blood
Blockages, or other Biologic conditions separate from the initial (incorrect?)
assumption. (Note, I think it was only incorrect insofar as the initial
comment that All seizures were caused by that type of disruption or
interference. The fact that mine were caused by Encephalitis, from a mosquito,
does *not mean that all the Other types of CP or other seizures were caused
by that starting point. There are *multiple routes we can take to get to CP
seizures without depending on just one source or starting point.)
I thought I should describe that for someone new who might be reading this
group since December, and might assume that those were the only possible
causes of seizures. We have a Whole mix of sources of seizures, among the
posters here, and many (most?) are not because of magnetic disruptions, as
many of the electrical misfiring types, during a seizure, can be caused by
many different causes. G./

And the 2 advertisements you probably don't see, that MedKB put up following
my post above, on my reader, supposedly from 'Goooogle' (Note misspelling),
selling Steel and Solid Titanium Magnetic therapy bracelets, and Magnetic
Bracelets for sale in UK, to cure Epilepsy, belong on Quackwatch, not a
medical condition group. G./
