Abstract

Attention plays an important role in audiovisual integration. To further explore the neural mechanism of audiovisual integration when the participants attended and unattended the stimulus, we designed a visual and auditory discrimination task that included ‘A stimuli’, ‘V stimuli’ and ‘AV stimuli’ presented on the right or left side of screen randomly. We adopt DCM method to model audiovisual integration in attended and unattended condition to investigate the neural mechanism of audiovisual interaction in these two conditions. The results showed that the audiovisual interaction in attention-condition was stronger than that in inattention-condition, which reflected the influence of attention on multisensory integration.
