It is uncertain yet whether quantitative EEG methodologies, which identify abnormalities in frequency or spatial distribution of cerebral rhythms not clearly visible to the eye, or longitudinal EEG studies in an individual patient, will be more diagnostically helpful especially in early Normal EEG. The “Berger band” (i.e., 1–30 Hz) is commonly used for routine visual analysis. The brain has a limited repertoire  The value of understanding the normal electroencephalogram (EEG) lies in developing the foundation to identify an abnormality with clinical relevance. Theta: has a frequency of 3.5 to 7.5 Hz and is classified as "slow" activity. It is perfectly normal in children up to 13 years and in sleep but abnormal in awake adults.

Localizing normal or abnormal brain waves in bipolar montages is usually accomplished by identifying "phase reversal," a deflection of the two channels within a chain pointing to opposite directions. The normal adult electroencephalogram (EEG) is not a singular entity, and recognizing and appreciating the various expressions of a normal EEG is vital for any electroencephalographer. During wakefulness, the posterior dominant rhythm (PDR) must display a frequency within the alpha band, although an absent PDR is not abnormal.

Den dag du ska genomgå ett sömn-EEG ska du inte dricka kaffe, te eller annan uppiggande dryck som gör det svårt att somna. The first step in learning how to interprete the adult EEG is to learn how to recognize and describe what normal looks like. If you are a novice and have only a few minutes before one of your teachers plans to pull up an EEG and grill you about what you see, then take a look at the following, and in this order: awake (double banana montage) don't overcall normal variants Aside from the usual background findings and artifacts, EEGs will often have normal variant patterns that, to an untrained eye, may appear to be epileptiform or otherwise pathological and thus are at risk of being overcalled and leading to unnecessary tests or treatments.

Characteristics of Normal EEG Thoru Yamada Elizabeth Meng Normal Awake EEG EEG shows considerable interindividual variability and also changes significantly depending on the level of consciousness. Further, there are progressive maturational changes from infancy, childhood, adolescence, young adulthood, and to the elderly. It is normal as the dominant rhythm in infants up to one year and in stages 3 and 4 of sleep.
