The main findings of the study are as follows:(1) Both N2 and P3 are the characteristic ERPs under nogo inhibition,but P3 amplitude is a good indicator of inhibition processing depth;(2) Through ERP waveforms separation from encoding of stimuli sequence,we verify that the capacity of visual working memory is about 4 units;(3) In the go/nogo sequence response, encoding is mainly the function of right hemisphere, but inhibition retrieval is concentrated on left frontal area and anterior cingulated cortex.
