WebThe EEG may also be used to determine the overall electrical activity of the brain (for example, to evaluate trauma, drug intoxication, or extent of brain damage in comatose patients). The EEG may also be used to monitor blood flow in the brain during surgical procedures. There may be other reasons for your healthcare provider to recommend an … Webpeaks of the ictal gamma activity are indicated by arrows at ∼60 or 70 Hz in the EEG channels. Activity from the deltoid muscles has much broader and noisier spectra than does gamma activity. The peaks of gamma activity on the scalp precede those of muscle activity by ∼200 ms. Delt., deltoid muscle. Time evolution of the frequency spectrum ...
