If you are deaf, while another hears, are my words not meaningful. I would say that content is contained in the radiation whether or not anyone senses it.

When apart from the body they are not organised to render information. Such information as they may contain related only to the fact that with machines we can detect the brain areas from which the emerge, and such inferences as to their thoughts and feelings are consistent with our knowledge of how those areas' functions.
That is not the same as saying that 'information' in a general sense cannot be gleaned from unintentional sources: pulsars, and quasars come to mind..
Maybe, had you been following and contributing to the thread, then you would not have misunderstood, who knows?
Yeah - like I said it's like you don't understand how to read.
Thanks for confirming my suspicion.
No it's you that doesn't know how to read:
"A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals."
"EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain." "Diagnostic applications generally focus on the
spectral content of EEG, that is, the
type of neural oscillations that can be observed in EEG signals."
Spectral content: "The frequency spectrum of a time-domain signal is a representation of that signal in the frequency domain. The frequency spectrum can be generated via a Fourier transform of the signal, and the resulting values are usually presented as amplitude and phase, both plotted versus frequency."
"Any signal that can be represented as an amplitude that varies with time has a corresponding frequency spectrum. This includes familiar concepts such as visible light (color), musical notes, radio/TV channels, and even the regular rotation of the earth. When these physical phenomena are represented in the form of a frequency spectrum, certain physical descriptions of their internal processes become much simpler. Often, the frequency spectrum clearly shows harmonics, visible as distinct spikes or lines, that provide insight into the mechanisms that generate the entire signal."
"Spectrum analysis, also referred to as frequency domain analysis or spectral density estimation, is the technical process of decomposing a complex signal into simpler parts. As described above, many physical processes are best described as a sum of many individual frequency components. Any process that quantifies the various amounts (e.g. amplitudes, powers, intensities, or phases), versus frequency can be called spectrum analysis."
There's also carrier frequency, pulse width and pulse repetition frequency to consider when trying to make sense of the data.
"Electromagnetic radiation (EM radiation or EMR) is a form of energy emitted and absorbed by charged particles, which exhibits wave-like behavior as it travels through space. EMR has both electric and magnetic field components, which stand in a fixed ratio of intensity to each other, and which oscillate in phase perpendicular to each other and perpendicular to the direction of energy and wave propagation. In a vacuum, electromagnetic radiation propagates at a characteristic speed, the speed of light."
"Electromagnetic radiation is a particular form of the more general electromagnetic field (EM field), which is produced by moving charges."
In summary, it would seem that much more could be gleaned from brain electrical activity, just not by history teachers, please leave electromagnetic energy to those that understand it.
