niedriggespanntes EEG


Senior Member
This is from a medical report in Germany

The full sentence is:

"Niedriggespanntes EEG mit mittel ausgeprägtem, gering amplitudenmoduliertem, frequenzstabilem alpha-Grundrhythmus (9-10/s, 20-50pµ) oder erhöhtem Anteil an beta-Aktivität"

How would "Niedriggespanntes EEG" be translated?
  • I'm absolutely no expert in the field, but from what I've seen so far, I think that "niedriggespanntes EEG" is a perhaps more jargon version of "Niederspannungs-EEG" (which can be found more frequently on the Internet; for example here, Max Planck Gesellschaft), which should be the equivalent of "low-voltage EEG".
    I didn't know that voltage is a usual dimension of an EEG. Obviously it is.
    EEG is measurement of voltages. Electroencephallogramm

    see also Sowka #5

    They are measuring the electrical brain waves.

    Electroencephalography - Wikipedia
    Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex.[1]
    PS: (more context)

    The signal recorded from ECoG is on a different scale of activity than the brain activity recorded from scalp EEG. Low voltage, high frequency components that cannot be seen easily (or at all) in scalp EEG can be seen clearly in ECoG.
