患有分离性身份障碍的患者对心理学和精神病学提出了独特的科学和临床挑战。我们很幸运地与一位患者合作，她在接受功能性核磁共振检查时，可以迅速、自愿地在主要人格(一名中年、高功能女性)和另一种人格(一名4-6岁的女孩)之间切换。一项独特的任务被设计来隔离在这些个性之间转换过程中发生的过程。数据来自两个相隔几个月的成像会议，每次都显示在这些个性之间切换时相同的激活区域。激活的区域包括：初级感觉和运动皮质，可能与转换过程中做出的特有面部动作有关；两侧伏隔核，可能与转换相关的奖赏方面相关；以及额叶前部，推测与人格转换涉及的执行控制有关。
Patients who suffer from dissociative identity disorder present unique scientific and clinical challenges for psychology and psychiatry. We have been fortunate in working with a patient who—while undergoing functional MRI—can switch rapidly and voluntarily between her main personality (a middle-aged, high-functioning woman) and an alternate personality (a 4–6-year-old girl). A unique task was designed to isolate the processes occurring during the switches between these personalities. Data are from two imaging sessions, conducted months apart, each showing the same activated areas during switches between these personalities. The activated areas include the following: the primary sensory and motor cortex, likely associated with characteristic facial movements made during switching; the nucleus accumbens bilaterally, possibly associated with aspects of reward connected with switching; and prefrontal sites, presumably associated with the executive control involved in the switching of personalities.
