摘要: Recent studies have investigated the neural correlates of how we perceive emotions individuals or a group using images individual bodily expressions. However, it is still largely unknown emotion dynamic crowd. This fMRI study used realistic videos large people expressing fearful, happy neutral emotions. Furthermore, were expressed by either unrelated in an interacting group. It was hypothesized that dynamics between crowd more salient signal than merely Second, expected interaction special importance fearful "panic" situation, as opposed to situation. Using fast-event related design, revealed observing interactive individuals, so independently expressive activated networks perception, execution and integration action emotion. Most importantly, panicked crowds, individually triggered anticipatory preparation activity, whereas brain less sensitive first assess effect collectively displayed important aspect emotional perception.
