Research Abstract	The results in the present study showed that functional connectivity observed in monkeys 'brains during watching other monkey's emotional expression(post-stimulus) was significantly changed depending on the stimulus(pre-stimulus) presented before the emotional expression. Thus, social context within the pre-stimulus affected the recognition of emotional expression presented in the post-stimulus ; this process was found in different functional connectivity in the brain. Therefore, by applying the analytical methods and the results in the present study to construct a mathematical model, we would develop a BMI for emotional recognition, which is our final goal of the present project.
