But Herta Flor of the University of Heidelberg in Germany, thinks she might have cracked it.
但德国海德堡大学的赫塔福罗却认为她可能已经破解了其中奥秘。
To understand what is happening, Dr Flor and her colleagues resorted once again to MRI, to record the brain activity of amputees while they were performing the mirror task.
福罗博士和她的同事为了弄清原理，再次求助于磁共振技术来记录截肢病人在进行镜像治疗时的大脑活动。
Dr Flor believes that, by removing the reinforcement loop and bringing in so-called pain-incompatible memories, traces of pain in the brain can be reduced or even extinguished.
福罗博士相信如果消除了强化环路，并引入所谓与疼痛不相容的记忆，那么疼痛在脑中的记忆痕迹会减少甚至消失。
That correlation led Dr Flor to wonder if the alleviation of pain caused by the mirror treatment might be the result of a reversal of the neurological changes associated with telescoping.
这种关联让福罗博士想知道是不是镜像治疗减轻疼痛的原理就是逆转了“伸缩”所带来的神经学上的改变。
Hey, listen, Flor, if you're tired…
听着，弗洛，要是你累了…
