Parent-child interaction is a significant part of human life, and a large portion of such interaction is carried out by eye contact. However, how the dyadic brain networks enable eye contact is not well understood. Here, we take advantage of fMRI hyperscan and concurrent eye tracking to measure the BOLD responses and pupil sizes during eye contact between parent and child. Our initial analysis begins to reveal some of the brain networks supporting the parent-child bond. A better understanding of such mechanisms may have a significant impact on human social life, and improve parent-child interaction therapy for many psychiatric diseases.
