EEG databases and EEG recording techniques.

Paper	Dataset Used	Patients	Recording	Sampling Frequency (Hz)/Resolution (Bit)	Characteristics
1, 7, 10, 12, 21	CHB-MIT	23	9 to 42 records for each patient.	256	Papers using this dataset have used all patient data except paper 7, which used only 22 patients’ data. Only paper 1 and 10 reported using 16-bit resolution in their sampling.
6, 9, 11–14, 16–17, 20, 22	Epilepsy Center of the Bonn University Hospital	5 sets	100 single channel EEG record per subset. 23.6 s each segment.	173.61	5 patient records are available labelled A, B, C, D, and E. However the studies used the following sets: 6,11,17—subset C, D, and E 9,16,20, and 22—used all sets 13 and 14—subset A, D, and E Study 12—subset A vs E Only paper 11 reported using 12-bit resolution in its sampling
5	Toronto Western Hospital Epilepsy Monitoring	12			All patient data were used in this paper; however, the sampling frequency is as below: 500 Hz (5 patients), 512 Hz(3 patients), 1000 Hz (3 patients) and 1024 Hz (1 patients)
7	Mount Sinai Epilepsy Center	28	86 scalp EEG recordings.	256	Only one study used this dataset
8	Institutional Review Boards of Xi’an Jiaotong University	10		200 samples/second	Only one study used this dataset
15	Neurology Department of the University Hospital of Rennes	5		2048	Only one study used this dataset
19	Mayo Clinic	6 (dogs)		400	Only one study used this dataset
