Abstract
A traditional method to extract human somatosensory evoked potential(SEP) is commonly averaging theory. Due to the defects of traditional averaging theory, what’s more, extracting SEP usually needs tens or hundreds times for averaging, we proposed an auto-reference, auto-correlative and adaptive interference cancellation theories and techniques (AAA-ICT) used in the single trial of somatosensory evoked potential (SEP) on the basis of analyzing the character of the spontaneous electroencephalo-signal (S-EES) and the special environment of extracting evoked potential (EP). This method avoids the defects of the traditional averaging theory for extracting SEP. The extracted SEP of single trial does not contain the averaging component and direct current component. Meanwhile the single trial of SEP describes more exactly about the differences of the latency and amplitude of SEP in detail.
