There have been two dominating theories for memory consolidation: the standard model (SM) and multiple trace theory (MTT). Whereas lesion studies have largely indicated a waning role for the hippocampus in memory consolidation, and thus have supported SM, findings from neuroimaging studies have produced varying results. Tallman et al. (this issue) argue that this variability may result from confounding factors and that, once these factors are accounted for, their neuroimaging results support SM. They do not, however, consider a third option: the unified theory. Here, we suggest that their findings, along with neurobiochemical and engram cell studies, may better fit this third theory.
一直以来，有两种占主导地位的记忆巩固理论：标准模型（SM）和多重痕迹理论（MTT）。虽然病变研究在很大程度上表明海马体在记忆巩固中的作用减弱，从而支持 SM，但神经影像学研究的结果却产生了不同的结果。Tallman 等人（本期）认为，这种可变性可能是由于混杂因素造成的，一旦考虑到这些因素，他们的神经影像学结果就支持 SM。然而，他们并没有考虑第三种选择：统一理论。在这里，我们认为他们的发现，以及神经生物化学和记忆痕迹细胞研究，可能更符合第三种理论。
