	Groups	Sizes of groups	Descriptions of EEG signals
Healthy people	A	100	EEG signals obtained with eyes open
	B	100	EEG signals obtained with eyes closed
Epileptic people	C	100	EEG signals measured in the hippocampus of the brain during seizure-free intervals
	D	100	EEG signals measured in the epileptogenic zone during seizure-free intervals
	E	100	EEG signals measured during seizure activity
