Which wave can help point out the place of a brain tumor?
ExplanationDelta waves have a frequency of less than 4 Hz. When a person is at rest, they will normally give alpha waves whose lowest range is 8 Hz. Thus, if there is a tumor formation, we can assume that a tumour is blocking the signal and so the electrode at the specific region reads a delta wave instead of an alpha wave when even though the other parts of the brain is giving an alpha wave.
