  • Frequency: >13 Hz
  • Normal in frontal en central area
  • Increase of beta due to medication: benzodiazepines, barbiturates and other sedative medications
  • Decreased focal beta activity is seen in cortical dysfunction, for instance infarction, abces, tumor, AVM etc.
  • Increased focal beta activity could be caused by cortical dysplasia, however sometimes also due to abces, tumor, AVM etc
  • Skull defects can cause focal, high amplitude, sharp beta activity (breach rhythm)
