A movement-associated fast rolandic rhythm.
A stereotyped 32 Hz rolandic rhythm maximal over the mesial cortex and occurring only with voluntary movement is described in a patient with tonic postural seizures. This abnormal but nonictal rhythm, which is probably generated subcortically, is expressed synchronously at the level of the cortex and peripherally in the EMG.
