Synthetic Epileptic Spike EEG Database (SESED-PW)

Synthetic Epileptic Spike EEG Database (SESED-PW)The database contains EEG, EMG, and EOG signals with artificially generated epileptic spikes. The recordings were performed using the g.USBamp 2.0 amplifier. Data were collected from 5 EEG channels (C3, Cz, C4, Fz, Fp1), 1 EOG channel (VEOG), and 3 EMG channels (Nape, Cheek, Jaw). The signals were sampled at 256 Hz and processed with a bandpass filter (0.1–100 Hz) and a notch filter (48–52 Hz).Participants were instructed to clench their jaws for 0.5–1 second, followed by muscle relaxation for 2–4 seconds, while sitting comfortably with open eyes. Each recording session lasted 3 minutes, capturing signals with prominent artifacts of high amplitude and broad frequency spectrum. These artifacts interfered with EEG signals and mimicked pathological changes observed during epileptic seizures.Artificially generated epileptic spikes, based on triangular signals, were added to the Cz channel in the presence of artifacts. The database contains signals from 20 participants (5 women, 15 men) aged 19–42 years. This resulted in 586 recordings with artificial spikes.
