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. 

合成癫痫尖峰脑电图数据库（SESED-PW）
本数据库包含带有人工生成癫痫尖峰的脑电图（EEG，Electroencephalogram）、肌电图（EMG，Electromyogram）及眼电图（EOG，Electrooculogram）信号。录制采用g.USBamp 2.0放大器进行。数据采集自5个脑电图通道（C3、Cz、C4、Fz、Fp1）、1个眼电图通道（VEOG）及3个肌电图通道（颈背、脸颊、下颌）。信号采样率为256 Hz，并经过带通滤波器（0.1–100 Hz）与陷波滤波器（48–52 Hz）处理。
受试者需舒适睁眼端坐，先紧咬牙关0.5–1秒，随后放松肌肉2–4秒。单次录制时长为3分钟，采集到的信号带有高幅值、宽频谱的显著伪迹。此类伪迹会干扰脑电图信号，并模拟癫痫发作期间观察到的病理变化。
基于三角信号生成的人工癫痫尖峰，被添加至存在伪迹的Cz通道中。本数据库包含20名受试者（5名女性、15名男性）的信号，年龄区间为19–42岁，最终得到586条带有人工尖峰的录制数据。
