Inclusion Criteria:  Patients with the diagnosis of simple and multifocal seizure or generalized seizure who are at least 1 year old but 19 years old at most, whose head the zEEG headset fits, and who also produced sufficient seizure and normal activity EEG data. This age range is all-inclusive, because the actual patient selection will be based on the head-sizes that the zEEG system will fit to.  Exclusion Criteria:  Patients younger than 1 year and older than 19 years, pseudo seizures, patients who did not generate normal EEG data or their EEG electrode setting is in conflict with the zEEG headset will be excluded. Patients who cannot keep the zEEG headset on their head will be excluded.
