ABSTRACT

In their recent review, Xu critically assesses the role of early visual areas in VWM storage in the light of new fMRI-decoding studies that seemingly support the sensory storage account. We would like to extend the discussion by highlighting recent findings which suggest that early visual areas can dynamically transform active VWM representations e.g., to activity silent or long-term memory representations. These latent codes evade detection via traditional paradigms as well as decoding methods and hence limit the conclusions that can be drawn about the role of certain brain regions in WM storage. More precisely we claim that a lack or a temporary disappearance of multivariate VWM evidence from early visual brain regions does not imply that these areas are not essentially required to store and maintain active, or currently attended, VWM representations.

摘要

在他们最近的评论中，徐根据似乎支持感官存储帐户的新 fMRI 解码研究，批判性地评估了早期视觉区域在 VWM 存储中的作用。我们想通过强调最近的发现来扩展讨论，这些发现表明早期视觉区域可以动态地将活跃的 VWM 表示转换为活动沉默或长期记忆表示。这些潜在代码通过传统范式和解码方法逃避检测，因此限制了可以得出的关于某些大脑区域在 WM 存储中的作用的结论。更准确地说，我们声称早期视觉大脑区域的多元 VWM 证据的缺乏或暂时消失并不意味着这些区域基本上不需要存储和保持活跃，或当前参与，
