Research has shown that dogs have brain regions that recognize and respond to human faces. However, little research has been done to examine how dogs respond to juvenile faces both within and outside of their own species. Humans show significant activation in the lateral premotor cortex, supplementary motor area, middle cingulate gyrus, anterior insula, thalamus, and fusiform gyrus, which are associated with preparedness to act and speak, social and emotional responsiveness, and parental attachment respectively. Thus, we scanned awake, unrestrained dogs that are trained for fMRI studies while viewing images of adult and infant humans and dogs. In our study, we found greater activation in the ectolateralis posterior within the dog face area at a significance level of p<0.05 in response to adult stimuli, a novel finding that we discuss potential reasoning for. This study gives us a better understanding of the relationship dogs have with humans and their ability to care for and bond with humans, and sheds insight into our understanding of dogs’ ability to form familial relationships outside of their species.
