fMRI for affective psychological studies

Taking advantage a newly developed dyadic fMRI system, this project studied two brains interactions via eye contact. This is the first direct observation of the dyadic affective states mediated by reciprocal visual stimulation. The dual system activation due to in vivo reciprocity, empathy system and metallization system, are clear evidences, while such systems often are not fully activated by pictorial stimuli. This method offers a direct and quantitative approach to estimate deficiency of Autism patients in close social relations.
