medium voltage Explanation: This most likely refers to quantitative EEG (qEEG) Quantitative electroencephalography (QEEG) is a field concerned with the numerical analysis of electroencephalography data and associated behavioral correlates. Fourier analysis of EEG The Fourier decomposes the EEG time series into a voltage by frequency spectral graph commonly called the "power spectrum", with power being the square of the EEG magnitude, and magnitude being the integral average of the amplitude of the EEG signal, measured from(+) peak-to-(-)peak), across the time sampled, or epoch. The epoch length determines the frequency resolution of the Fourier, with a 1-second epoch providing a 1 Hz resolution (plus/minus 0.5 Hz resolution), and a 4-second epoch providing ¼ Hz, or plus/minus 0.125 Hz resolution. https://en.wikipedia.org/wiki/Quantitative_electroencephalog... ccccccc The alpha waves are replaced by low-voltage slow activity, mainly in the range of 2 to 7/sec. ... Rhythmical 5 to 7/sec activity is noted over posterior regions very shortly after the disappearance of alpha waves. ... Trains of 2 to 3/sec and 4 to 7/sec waves reach medium voltage and may become diffusely predominant. https://books.google.com/books?id=xSKqZxXOlukC&pg=PA199&lpg=... ccccccccccccccccc Thalamic Mechanisms of EEG Alpha Rhythms and Their Pathological Implications Medium-voltage 5-9-Hz oscillations give rise to spike-and-wave discharges in a genetic model of absence epilepsy: in vivo dual extracellular recording of thalamic relay http://journals.sagepub.com/doi/abs/10.1177/1073858405277450 cccccc Low- to medium-voltage continuous activity with semirhythmic thetaialpha waves. Almost continuous theta-alpha waves without sleep cycles are infrequently seen in purulent meningitis (Watanabe et al. 1983ft) or intracranial haemorrhage (Watanabe et al. 1981). In such cases, subclinical or clinical status epilepticus is often https://books.google.com/books?id=oqbjehD4U0AC&pg=PA32&lpg=P... |
