Spontaneous emotional expressions are related to the person’s real emotions and are important in understanding the meaning and effects of emotions in social interactions. The present study attempts to examine the happy facial expressions and its related brain regions. 27 young adults were recruited and completed an experiment to view dynamic happy and neutral facial expressions as well as objects in motion in an er-fMRI paradigm. We found that emotional faces were having higher activities than the processing objects (non-face) with motion at right middle temporal gyrus, left fusiform gyrus, right superior temporal gyrus, left middle occipital gyrus, right thalamus, and right middle frontal gyrus. It was also found difference in between processing happy expressions and neutral faces at the right superior temporal gyrus, left cuneus, right middle Occipital Gyrus, right inferior frontal gyrus, and right Lingual Gyrus. Processing the neutral faces were higher than processing objects at right middle and superior temporal gyrus, left precuneus, and left angular gyrus. These findings may help to elucidate the nature of processing dynamic happy facial expressions.
