Asymmetry, unilaterality, or asynchrony of the mu rhythm is generally not abnormal unless associated with other abnormalities. Very high-voltage mu activity may be recorded in the central regions over skull defects and may become sharp in configuration, and thus can be mistaken for epileptiform discharges. [8] When mu rhythm is detected in an EEG, it should be verified by testing its reactivity.
