Objective: To explore the neural mechanism of cerebral function deviation in the processing of emo-tional vocabulary for Chinese words with multi-channel ERPs analysis techniques. Methods: 31 sub-jects were required to complete the five levels of emotional valence emotions evoked EEG test po-tential discrimination with the different emotional valence of emotional stimuli picture emotions and to observe the emotional responses of the subjects to the five emotional valence levels. Results: ERPs statistical parametric mapping diagram (SPM) results: In the Middle and late stage, extremely negative and partial negative words were activated at the bilateral cortex widely of orbitofrontal and ventromedial prefrontal, anterior cingulate and somatosensory, high frequency wave, large am-plitude, long time, activation effect right. Neutral words activation affects more in the left cortex, low frequency, low amplitude; positive and partial positive words were activated the range for bilateral cortex widely of orbito-frontal and ventro-medial prefrontal, anterior cingulate and somatosensory, frequency. Compared with negative activation, the amplitude, frequency and time domain were ob-viously decreased, left cortex was significantly activated. Conclusion: Different emotional valence words processing prompts that negative emotional words processing to be activated effect in right cortex, and positive emotional words processing to be activated effect in left cortex. Speculated the response of brain on the emotional stimuli left-right hemispheric differences in is based on pro- cessing machining difference, the differences in the functional mode may is memory attention to specific neural mechanism of the difference between the cognitive ability.
