AbstractObjective To compare the studies on event related potentials(ERP) evoked by single visual,auditory and somatosensory target stimulus modes,and discuss the possibility of electrical stimulated somatosensory using in brain computer interface(BCI) system as the new method and provide theoretical basis for BCI based on somatosensory ERP. Methods A total of 17 volunteers with normal vision or corrected visual acuity and normal hearing and somatosensory function without any brain history were enrolled,included 8 males and 9 females,aged 20-26 years old with mean age of 22.6 years old,and all of them were right-handed. The electroencephalograph of volunteers evoked by uni-modal target stimuli of visual,auditory and somatosensory was recorded,respectively. The time parameters(amplitudes and latencies) of ERP,behavioral(reaction time and error rate) and dipole source locations of 3 stimulus modes were analyzed and compared. Results The ERP waveforms of 3stimulus modes were similar,the ERP amplitudes of somatosensory,visual and auditory stimulus modes were no significantly correlated,and ERP latencies of somatosensory stimuli were significantly longer than that of visual stimuli. The action time of somatosensory stimuli were significantly longer than that of visual stimuli,and error rates were also higher than both visual and auditory stimulus pattern. The dipole source locations under single somatosensory and visual stimulus mode were similar.Conclusion It is demonstrated that human brain is more difficult than visual and auditory uni-modal stimuli in detecting and perceiving electrical stimulated somatosensory,but electrical stimulus could evoke stable somatosensory ERP waveforms,which could become the new stimuli mode for BCI application. 目的對視覺、聽覺、體感3種不同模態下靶刺激誘發的事件相關電位(ERP)進行比較研究,探討體感電刺激作為腦機接口(BCI)一種新的信號誘發模式的可能性,為基於體感ERP的BCI研究提供理論依據。方法選擇17例視力或矯正視力正常、聽力正常、軀體感覺正常且無任何大腦病史的被試者,其中男性8例,女性9例;年齡20~26歲,平均年齡22.6歲;均為右利手。分別記錄17例健康的被試者在視覺、聽覺、體感單通道靶刺激下誘發的腦電圖;對3類靶刺激下ERP的時域參數(幅值、潛伏期)、行為學數據(反應時間、錯誤率)、腦源定位進行比較分析。結果3類靶刺激模式下的ERP波形具有相似性,體感電刺激誘發的ERP幅值與視覺、聽覺靶刺激相比無顯著性差異;體感電刺激誘發ERP的峰值潛伏期顯著長於視覺靶刺激;體感電刺激的反應時間顯著長於視覺靶刺激,錯誤率也高於視覺、聽覺靶刺激;體感電刺激誘發ERP的腦內源與視覺靶刺激相比具有相似性。結論相比於視覺、聽覺靶刺激,大腦對於體感電刺激的探測難度高,敏感程度低;但從ERP的波形和幅值上看,體感電刺激可以誘發出穩定的、可被檢測到的ERP波形,完全有可能應用於BCI系統作為一種新的ERP誘發模式。
