在我们的日常生活中，识别一个熟悉的物体是一个毫不费力，似乎瞬间的过程。然而，我们对大脑如何完成这一艰巨任务的了解非常有限。本研究采用整体的方法来研究识别记忆的神经过程。一个独特的范例，其中的视觉信息的身份的一个人或一个字是慢慢滴定到人类观察员在功能成像会话，被用来揭示大脑中的视觉识别的动态。研究结果揭示了视觉识别的多个独特阶段，这些阶段可以根据时间顺序和血流动力学反应特征彼此分离。(c)2006年爱思唯尔公司All rights reserved.
In our daily lives, recognizing a familiar object is an effortless and seemingly instantaneous process. Our knowledge of how the brain accomplished this formidable task, however, is quite limited. The present study takes a holistic approach to examining the neural processes that underlie recognition memory. A unique paradigm, in which visual information about the identity of a person or word is slowly titrated to human observers during a functional imaging session, is employed to uncover the dynamics of the visual recognition in the brain. The results of study reveal multiple unique stages in visual recognition that can be dissociated from one another based on temporal asynchronies and hemodynamic response characteristics.
