| Outline of Final Research Achievements |
We investigated parental brain responses to two-year-old child’s feeding situation using fMRI. We also examined the activations of four regions associated with parenting motivation such as parental love including orbitofrontal cortex (OFC), periaqueductal gray, dorsal raphe nucleus, anterior insula cortex, and ventral pallidum.
We found that the OFC which plays a critical role in reward system and representing the value of a stimulus reward was significantly activated in mother’s brain, but not in father’s brain. Our findings suggest that well-balanced maternal brain mechanisms integrated by OFC provide effective adaptive responses in daily parenting.
