Frequency asymmetry of sleep spindles associated with focal pathology.
Focal cerebral lesions are often associated with voltage asymmetry of sleep spindles, usually with depressed voltage on the side of the lesion. In this report, we document a case in which a brain tumor was associated with a frequency asymmetry in addition to a voltage asymmetry of sleep spindles. The slower frequency spindles occurred on the side of the lesion.
