Coordination sex, brain reflect the integrated treatment of a variety of visual, auditory and tactile perception , so that the study of brain cognition and behavior to learn the relevance of great significance . In order to study how the brain processing the input information in the different modes , information integration occurs , visual , auditory and tactile three angles in the single-mode stimulation EEG source analysis based on the audio-visual dual-mode state , audio-visual touch 3 - modal stimulation EEG dipole source analysis . Obtained by comparison with single-mode stimulus dipole source source is not equal to the simple sum of the single-mode stimulated brain-derived cross - modal stimulation of the brain , suggesting that the brains of the integration of the different perception of information and depth of processing paper, 64 the guide NeuroScan4.3 EEG acquisition system by the subjects in the experiment be made as soon as possible to target stimuli responsive keys , recorded seven subjects , audio-visual at the same time in separate visual, auditory and tactile stimulation and audio-visual the touch while stimulating the EEG , to and use Curry6.0 software dipole source analysis of EEG data in the early , mid-and late ERP component . This paper demonstrates that a separate visual , auditory, tactile stimulation of the source of the early results were located in the occipital lobe , temporal lobe , posterior central gyrus , consistent with previous studies reported . In different time frames , the same time through the audio-visual source results in the stimulation and a separate visual source , auditory source Comparative found that the audiovisual stimulation source includes not only the separate visual source and separate auditory source , and also the presence of ( 1 ) the early and mid multi-channel sensory areas , such as the hypothalamus , frontal and parietal brain regions , (2) advanced single-channel feedback such as the occipital lobe, temporal lobe brain regions . To study different time periods through audio - visual touch stimulation source and a separate visual source , auditory source , touch the source , it was found that the source audio-visual touch while stimulating not only include a separate visual source , a separate hearing source and a separate tactile source , in addition to multi-channel (1) early and mid- sensory areas , such as frontal, cingulate cortex , hippocampus , ( 2 ) advanced single-channel feedback back to the brain regions such as the occipital lobe, temporal lobe , the central . Experimental results show that the feeling of cross- stimulation of the brain, a multi-channel interaction , and to provide new information for further study of the brain cognitive .
