Attribute 4: Magnitude:: = describes the amplitude of the EEG activity if it is emphasized in the EEG report Low: e.g. subtle (spike), small (polyspike discharge) High: e.g. high (voltage burst); high amplitude (spike); excess (theta) Normal: the default value	Attribute 5: Recurrence (TEMPORAL):: = describes how often the EEG activity occurs. Continuous: the activity repeats in a continuous, uninterrupted manner Repeated: the activity repeats intermittently None: the activity occurs once
Attribute 6: Dispersal (SPATIAL):: = describes the spread of the activity over regions of the brain Localized (focal): limited to a small area of the brain Generalized (diffuse): occurring over a large area of the brain or both sides of the head	Attribute 7: Hemisphere (SPATIAL):: = describes which hemisphere of the brain the activity occur in. Right Left Both
Location Attributes: Brain Location (SPATIAL):: = describes the region of the brain in which the EEG activity occurs. The BRAIN LOCATION attribute of the EEG Activity indicates the location/area of the activity (corresponding to electrode placement under the standard 10-20 system). Attribute 8: Frontal (i.e. Anterior): Corresponds to the frontal region of the brain including all F*, Fp* and AF* electrodes Attribute 9: Occipital (i.e. Posterior): Corresponds to the occipital region of the brain including all O* electrodes Attribute 10: Temporal: Corresponds to the temporal region of the brain including all T* electrodes Attribute 11: Central: Corresponds to the central region of the brain including all C* electrodes Attribute 12: Parietal: Corresponds to the parietal region of the brain including all P* electrodes Attribute 13: Frontocentral: Corresponds to the area between the frontal and central regions of the brain including all FC* electrodes Attribute 14: Frontotemporal: Corresponds to the region between the frontal and temporal regions of the brain, including all FT* electrodes Attribute 15: Centroparietal: Corresponds to the region between the central and parietal regions of the brain including all CP* electrodes Attribute 16: Parieto-occiptal: Corresponds to the region between the parietal and occipital regions of the brain including all PO* electrodes
