Answer

In the classification used here, the term asymmetry refers to asymmetry of amplitude and to normal rhythms. By contrast, a focal frequency asymmetry would be classified as focal slow. [1] Finally, readers should keep in mind that amplitude asymmetries should be evaluated on referential montages, since amplitude is highly dependent on interelectrode distances.
