Abstract：
Sensory visual areas are involved in encoding information in visual short-term memory (VSTM). Yet it remains unclear whether sensory visual cortex is a necessary component of the brain network for maintenance of information in VSTM. Here, we aimed to systematically review studies that have investigated the role of the sensory visual cortex in VSTM using transcranial magnetic stimulation (TMS) and to quantitatively explore these effects using meta-analyses. Fourteen studies were identified and reviewed. Eight studies provided sufficient data for meta-analysis. Two meta-analyses, one regarding the VSTM encoding phase (17 effect sizes) and one regarding the VSTM maintenance phase (15 effect sizes), two meta-regressions (32 effect sizes in each), and one exploratory meta-analysis were conducted. Our results indicate that the sensory visual cortex is similarly involved in both the encoding and maintenance VSTM phase. We suggest that some cases where evidence did not show significant TMS effects was due to low memory or perceptual task demands. Overall, these findings support the idea that sensory visual areas are part of the brain network responsible for successfully maintaining information in VSTM.
摘要：
感觉视觉区域涉及视觉短期记忆（VSTM）中的信息编码。然而，目前尚不清楚感觉视觉皮层是否是维持VSTM信息的大脑网络的必要组成部分。这里,我们旨在系统回顾使用经颅磁刺激(TMS)研究感觉视觉皮层在VSTM中的作用的研究,并使用meta分析定量探讨这些影响.确定并审查了14项研究。八项研究为荟萃分析提供了足够的数据。两个荟萃分析，一个关于VSTM编码阶段(17个效果大小)，一个关于VSTM维护阶段(15个效果大小)，两个元回归(每个32个效果大小)，并进行了一项探索性荟萃分析。我们的结果表明，在编码和维持VSTM阶段，感觉视觉皮层都有类似的参与。我们建议，在某些情况下，证据未显示出显着的TMS效应是由于记忆力不足或感知任务需求所致。总的来说,这些发现支持了这样一种观点,即感官视觉区域是负责在VSTM中成功维持信息的大脑网络的一部分.
