The articles are truly outrageous in their claims.
Ok, let's see what you have a problem with then.

After reading all the articles, I can say I have truly wasted my time. The "physics" while it may seem probable to a lay person, leave out the
specific reasons this cannot work.
Ok, Einstein, let's see what you've got...

Firstly, we have billions of neurons in our brain and yes, they do generate electrical signals. The problem is that each neuron is not purely
electrical in its transmission. The electrical component is only across the axons. In the body of the nerve, the signal is chemical and undetectable
externally. So each nerve firing is only transmitting electrically for the briefest instant and the signal is then broken and resumed at a spatially
different point. While this is a rapid process (at approximately 15 meters per second) it is far too slow and broken-up to generate radio frequencies.
As noted in the article, the wavelength generated is somewhere in the 300 to 1,000 kilometer range. For efficiency, this would require antennae on the
same scale on both the transmitter and the receiver ends. Obviously our heads are too small to make an effective transmitting antenna.
Ok, I can see how this causes confusion in the lay person. That doesn't mean its not accurate. The "signal" is not chemical. In technical terms,
the electrical potential across the membrane of a cell is changed by the incoming neurotransmitter and ions (usually calcium).
If you listen to ELF signal produced by cluster of neurons, you will notice that it fires at a particular rate and that there are multiple signals
which are slightly out of phase as it propagates down through the cluster. By emitting photons that match that ELF signal, we can drive that cluster
externally. Emit photons of a higher energy and the cluster will speed up, lower energy and the cluster will slow down. These ELF frequencies are
very narrow and are quantized, that is a ramp up or down is performed in steps.
There are different encoding schemes, but for illustration purposes we will only use rate encoding.
As you state, "for efficiency", an antenna of the same length or fraction of that wavelength should be used. There is a different way and the key
to understanding this is absorption. The membrane is electrically excitable and will absorb photons at a certain frequency, this happens to be the
same frequency at which it emits. This, in more technical terms, makes the neuron or cluster a transducer.

Then we have the signal strength issue. Sure, we can detect very low power signals, but those signals get less and less in an inverse square of the
distance traveled. In a few meters, they would be way below the detectable threshold.
Deepthought does the calculations for a distance of 500 Km.
Neuron at 500Km
PDs = 0.00000002079
PDr = 6.6176625337610080612701868810291e-21
dBW = -201.7929538336266467100376834869

-200dB is nothing that modern equipment cannot detect.

Then there is the issue of discriminating the signal of one persons head from that generated by many others nearby. With a wavelength at a minimum of
300 kilometers, people even with in a 30 kilometer range would be undifferentiable from each other. Spatial and phase differences with such a low
frequency, especially one already on the threshold of detectability, would be way below the charge on a single electron (which sets the lower limit on
the physical detectability of electrical signals).
It depends on the receiving network. Deepthought shows that 10m resolution would require a sensitivity of:
dBW = 0.00017371605560653514299128770107489

There are numerous ways around that, such as watching targets moving to different locations, or using visual identifications by the A.I.

In short, possible.
