Two parallel fMRI experiments were conducted with the aim to clarify the lateralisation issue of the cerebral network underlying autobiographical memory retrieval independently of the stimulus material and the refreshment of the memory trace. The verbal experiment required a pre-scanning interview, while the nonverbal version tested the subjects directly during the fMRI session. Both experiments were constructed using the same experimental design to eliminate methodological variables in order to render comparisons possible. We found a predominantly left-lateralised cerebral network independently of material and regardless of whether or not memory traces were reactivated prior to the scanning session. We discuss the results in the context of neuroimaging studies of autobiographical memory (AbM).
进行了两项平行的功能磁共振成像(fMRI)实验,目的是独立于刺激材料和记忆痕迹的刷新,阐明自传体记忆检索背后的大脑网络的偏侧化问题。言语实验需要进行扫描前访谈,而非言语版本则在fMRI扫描期间直接对受试者进行测试。两项实验均采用相同的实验设计构建,以消除方法学变量,从而使比较成为可能。我们发现,无论材料如何,也无论在扫描前记忆痕迹是否被重新激活,大脑网络主要呈左侧化。我们将在自传体记忆(AbM)的神经影像学研究背景下讨论这些结果。
