Electroencephalography

THE NATURE OF EEG WAVE GENERATION
If we consider EEG waves as the recorded sum potential of neuronal pools in the cortex,
several contentious questions arise.
With the amplification of afferentation, i.e., the influx of electrical potentials into the cortex,
there is a depression of waves on the EEG, indicating a decrease in amplitude and a reduction
in the strength of cortical potentials. Interestingly, the International Committee on
Terminology prohibits the use of the term ‘depression’ and suggests ‘activation’ instead.
Unfortunately, the true nature of electrical phenomena in the brain does not necessarily
align with this authoritative committee. During the reinforcement of afferentation into the
cortex, a flow of electrical energy enters. If this is not reflected in the EEG, the
straightforward conclusion is that EEG recordings do not register cortical potentials.
It is commonly accepted that an activated cortex is reflected in low EEG amplitude. A similar
EEG pattern during deep sleep seemed so paradoxical that it entered terminology. It would
be paradoxical if during deep sleep, when electrical currents are detained in the sub cortex
|thalamus and brainstem|, some potentials were registered.
Pathologically inhibited foci in the cortex exhibit high waves, indicating the presence of
directed electrical energy. The explanation that these potentials are generated by bordering,
still viable cells is naive and inconsistent with practice. These waves are the largest in the
centers of cortical foci, more so than in the peripheries. In extensive cortical lesions or
decortications, EEG manifests with the appearance of high voltages, which neurons,
especially cortical ones, could not generate.
If functions are distributed in the cortex, it should be reflected in the EEG if it indeed shows
potentials of cortical neurons. However, as known, this is not the case.
From the above, a simple, logically sound conclusion follows: the recorded potentials on the
EEG, including those in cortical graphs and deep registrations, cannot be potentials of
neurons. It’s no wonder that the interpretation of EEG remains a contentious issue, the
subject of numerous discussions, relying solely on how well the recording aligns with known
nosology
