It's not only the cost, but a matter of factibility. he signals are too weak to be detected. The low frequency means that you would also need very large antennae to pinpoint a single individual, to get a decent signal above noise and to resolve it from the rest. The ionosphere is also an additional problem. This is pure bullshit.

No, it's the technology as well. Try measuring magnetic fields generated by the brain. You need a magnetically insulated room and an array of super conducting quantum interference devices (SQUIDS, no joke) all stationary relative to the brain, because those magnetic fields are in the order of 100 femto Tesla strong. Even then you can't interpret perception if the activity is not coupled with some behavioral task and lots and lots of trials.

If you measure electrical activity directly you need a bunch of electrodes in direct contact with the scalp via conducting gel to be able to measure anything. Even than you need a magnetically shielded room or your signal will be noisy as fuck.

At present it's not possible to measure brain activity from a distance other than with fMRI. Let alone from outer space.

Yes, but electrical activity is smeared out by the skull, scalp and dura. Also, current sources that are parallel to each other cancel each other out due to volume conduction. Electrical activity from deep brain sources is not measurable for the same reason. This makes electrical activity a very unpractical measure if your goal is to measure it from a distance.

That is the frequency used in OP's sources, and then proceeded to use calculations in power loss at 144 MHz, considering that the size of the sources and appropriate detectors change with wavelength due to beam size.

> They only reflect a proportion of the energy, it does not block signals. That's a simplistic view of the situation for beginners.

It doesn't include it there because it already considers integrated power.
The integrated power depends on frequency.
The energy of an electromagnetic wave is E = h*f (with h=Plack's constant and f=frequency),
so power necessarily depends on frequency. Now, if you don't know the relationship between
power and energy, you're lost.

Not so fast. The abstract says:

This work is a feasibility study of the possibility of transmitting ELF pulses at 1.4kHz to the GEOS satellite. Design considerations point to the use of a 56km horizontal transmission line as an aerial. The radiation field of this aerial at 95km height is rigorously computed using a full wave program, and the wave field amplitude produced at GEOS is roughly estimated. It is concluded that observable signals may be produced at GEOS but that nonlinear triggered emissions would require a high degree of plasma instability.

http://adsabs.harvard.edu/abs/1974evrw.conf..361N

Brain activity is often at f<100 Hz as far as I know.
There is no evidence of a significant radio signal detectable at even closer ranges. (I've only found a claim in a low-tier, not-peer-reviewed document of a possible detection in the range of a meter or so, so I would leave it at no necessary evidence provided yet).
Moreover, the mechanism described there is much more complicated and big.

And even in this highly prepared case the detectability of the signal at a distance closer than 500 km requires special conditions.
So to recap:
- no _firm_ evidence of brain radio signals at close range
- no evidence that in the best case would be detectable
- stolen, unrelated plots
- lack of references for several important steps
- unreferenced plots
- sloppy calculations in OP's source
- unwarranted connections between pieces of argumentation
- high atmospheric opacity in the relevant range
- no reference on the possibilities of reconstructing a weak signal in the relevant range after passing the ionosphere
- no references to the problems of background noise
- no knowledge of basic physics by the apologists of OP's source
- etc

There you have it, a perfect 0/10.

> It just the equipment...$1000 antenna versus $500 million satellite.
You have no idea what you're talking about. I'm talking of no evidence presented here of significant radio emission from a human brain (and related to the brain activity that OP's source claims can be detected, of course), detectable at close range.
If that evidence is presented, I would expect an measurement of radiated power, and feasibility for use in decoding. That means that you not only need to detect the signal, but to have BOTH spatial and temporal resolution better than what can be achieved with traditional methods, to compensate for further distortions in the signal. So this is yet another argument AGAINST OP's source, which is now a steaming pile of shit.

the two posters that mentioned the action potential has two components, this is accurate. The motion of the ions, in and out of the gates, depolarizes or hyperpolarizes the membrane. This changes the potential across the membrane causing the electric field to move.

So, they are bang on the money. Volume conduction applies to the current from the moving ions. The electrical field is under no such restrictions, as its relationship with the current is indirect.

Stop samefagging idiot.

An electrical field is generated by the flow of ions. That's the definition of a <span class="math">{\bf current}[/spoiler]. The field it generates is the same for post synnaptic potentials and action potentials. Of cource volume conduction fucking applies, what else would it relate to? Even the first fucking scentence of the article I linked to states this:

>An electrical field is generated by the flow of ions. That's the definition of a {\bf current}. The field it generates is the same for post synnaptic potentials and action potentials.

The field is not generated by the flow of ions. The electric field is produced by the membrane. The ions merely change the electric potential of the axon's membrane.

Volume conduction is applicable to EEG and MEG. It is not applicable to the articles.

Of course you can, the articles show that neurons emit radio waves and it is detectable. That is a given.

EEG uses induction, and MEG uses magnetic induction, but nothing is looking at the emanations in weak radio signals from the action potential.

If memory serves, volume conduction is related to induction not radiation.

Wow, this is the first sane thing you've said.

The study has several flaws:

- It's not peer reviewed. If it's "correct enough", it needs validation by independent groups. You just can't give credibility to this case based on only one study. If this can be reproduced consistently by more teams (and published), discarding clearly other possibilities, only then I would consider this as evidence.

-"Although this record was made in the screened free-field chamber, it is obvious from the time path that very strong industrial interference was present."
Then:
"The spectral analyse can give us more information."
A spectrum gives you not spatial information. They haven't proved the source is not elsewhere.

- They are not clear in the geometry of the experiment. They mention a stronger signal when "the inductive coil sensitivity for man presence was on its highest if oriented in east-west direction."

- I would expect the use of a medical dummy of similar size as a comparison.

- They only show one of several plots. I want to see the other ones.

That's poor as a source, sorry. It looked promising at first, but under attention to details, it fails.
Also, since these signals were supposedly detected in a field-free chamber. If they can detect the same signal _without_ the chamber with maybe more sensitive instruments, only then there would be a case. Then they would have to prove that:
- the signal comes from the brain and only from the brain
- the signal is persistent and related to specific brain activities
- you can associate these signals to specific stuff
If you can't detect this without a chamber, much less from orbit. And there are still several other problems with the claims of the article.

Sorry, but not convinced.

>> No.1950439

>It's not peer reviewed

Not much to peer review in a signal.


>A spectrum gives you not spatial information. They haven't proved the source is not elsewhere.

If you are walking in front of the attena and it spikes every time, i'd say its pretty solid.


>They are not clear in the geometry of the experiment. They mention a stronger signal when "the inductive coil sensitivity for man presence was on its highest if oriented in east-west direction."

Not a big issue but interesting.


>the signal comes from the brain and only from the brain

It comes from neurons firing. That can be any neuron. Most likely they are seeing motor neurons.


>the signal is persistent and related to specific brain activities

That's by implication. DeepThought's articles show how this mechanism works.


>you can associate these signals to specific stuff

See the article.

Peer review is much more than simply looking at the signal. You also evaluate
the procedures, logical steps, you ask for more details, check plots, and can even ask
for some archived data. You clearly don't know much about the scientific process.

> If you are walking in front of the attena and it spikes every time, i'd say its pretty solid.
Correlation is not causation. You also must check the timing between walks and other possible periodic sources, and test other effects. It needs more plots of other runs.

> Not a big issue but interesting.
It is an issue since they were measuring in a radio-noisy place.

> It comes from neurons firing. That can be any neuron. Most likely they are seeing motor neurons.
There is no evidence for that there. You are trying to associate a measurement with a specific mechanism, but the experiment isn't even conclusive on the source. If these are signals from motor neurons, it's not a support for OP's article, concerned with brain activity.

> That's by implication. DeepThought's articles show how this mechanism works.
Those are mere claims, they are useless without evidence.

>you can associate these signals to specific stuff
> See the article.
The one about the experiment only makes _claims_ regarding that. It doesn't settle the case.
There IS a difference between a claim and scientific evidence supporting a claim. It seems you fail to see that.
It doesn't show the association experimentally. If it's the web page, those are mere claims.


> $1000 antenna verus $500 million dollar satellite. I'm sure there would be more than a minor difference.

Bullshit. There is only a possible correlation that needs independent confirmation.
That it's not a peer-reviewed article is a BIG FUCKING issue. If you can't understand this, you have even less credibility.

You have still not provided an experiment that shows clearly:
- that radio waves are produced by the human body as a product of neuronal activity, let alone brain activity.
- that these radio waves, if they exist, can be detected a few meters away.
- that money makes a difference for this specific case; if you don't have the physics, money is useless.
- that the signal would be detectable 500 km away.
- that the signal would carry some information on brain activity.
- that the signal can be processed over ambient noise and the information gathered to a satisfactory level.

This is what you have provided (whether you've been always the same, or several people):
- A web site with unrelated, stolen and/or unreferenced plots; full of unwarranted claims given the limitations of the sources, some of them of bad quality.
The good ones only support primary ideas, but not the logical steps to build a solid argumentation.
- ONE non-peer-reviewed study that shows a seemingly temporal association between human presence and a signal that they already expected to find, in a radio-noisy place, omitting more plots. Poor treatment of geometrical factors and noise. Lack of supporting _additional_ papers that can confirm the validity of the experiment.
- Lots of bald claims, which are useless.
- Lack of decent knowledge in physics, since you can't see even the most basic problems in the sources.
- Arguments that do not help to the case, like the satellite that was rather directed to ionospheric/magnetospheric measurements, the GPS satellites that operate in different ranges at different resolutions, etc.
- Failure to understand and address the problems of atmospheric blocking and noise. Again, only claims of -35 dB. No source provided.
- Repetition of the same arguments that have already been debunked.
- An alarming lack of solid calculations and models.
- A claim of people being attacked by something you can't even prove it's remotely possible.
