Data and code from: A meta-analysis suggests that TMS targeting the hippocampal network selectively improves episodic memory

Episodic memory is critically dependent on the hippocampal network and is frequently impaired in many clinical disorders. Recent findings highlight Hippocampal Indirectly Targeted Stimulation (HITS) as a promising, noninvasive transcranial magnetic stimulation (TMS) procedure to enhance episodic memory performance. Here, we report the first comprehensive meta-analysis of HITS effects on episodic memory, encompassing both healthy individuals and clinical populations. HITS robustly improved episodic memory, with effects selective for episodic memory versus other non-memory cognitive domains. Efficacy was significantly greater when memory performance was assessed using memory tasks sensitive to recollection, which is strongly linked to hippocampal network function, compared to recognition or other types of episodic memory tasks. Efficacy was also significantly greater when HITS was delivered before the memory tasks were administered, versus in the period between the study and test phases o..., , # Data and code from: A meta-analysis suggests that TMS targeting the hippocampal network selectively improves episodic memory Dataset DOI: [10.5061/dryad.vhhmgqp86](https://doi.org/10.5061/dryad.vhhmgqp86) ## Description of the data and file structure The analysis_dataset.csv file is a table of standardized effect sizes used in the meta-analysis, organized by reviewed study and categorized based on the experiment design factors that were assessed. The data are organized such that each row has one effect as well as all the study and factor categorizations for that effect, organized by columns. The first row is a header that indicates the study and factor information provided in each column. The HeaderDataDictionary_v3.txt file is a description of how the data in analysis_dataset.csv correspond to the factor descriptions used in the meta-analysis reported in the corresponding publication, described in Tables 1 and 2 of the HeaderDataDictionary_v3.txt file (and in Table 1 and Table S1..., ,情景记忆（Episodic Memory）高度依赖海马网络（hippocampal network），且在多种临床疾病中常出现受损。近期研究表明，海马间接靶向刺激（Hippocampal Indirectly Targeted Stimulation, HITS）作为一种极具前景的无创经颅磁刺激（noninvasive transcranial magnetic stimulation, TMS）手段，可有效提升情景记忆表现。本研究首次针对HITS对情景记忆的影响开展全面元分析，研究对象涵盖健康个体与临床患者群体。结果显示，HITS可显著改善情景记忆，且其效应仅特异性作用于情景记忆，对其他非记忆认知领域无显著影响。相较于再认任务或其他类型的情景记忆任务，当采用对情境提取敏感的记忆任务评估记忆表现时（此类任务与海马网络功能密切相关），HITS的疗效更为显著。此外，相较于在学习与测试阶段之间施加刺激的方案，在记忆任务实施前进行HITS的疗效同样更为突出…… # 数据与代码来源：一项元分析表明靶向海马网络的TMS可选择性改善情景记忆 数据集DOI: [10.5061/dryad.vhhmgqp86](https://doi.org/10.5061/dryad.vhhmgqp86) ## 数据与文件结构说明 analysis_dataset.csv 文件为本次元分析所用的标准化效应量表格，按纳入的已审阅研究进行整理，并根据评估的实验设计因素进行分类。数据组织形式为：每行对应一个效应量，同时包含该效应量所属研究的全部信息与因素分类，以列进行组织。第一行为表头，标注了各列对应的研究与因素信息。 HeaderDataDictionary_v3.txt 文件用于说明 analysis_dataset.csv 中的数据与对应已发表元分析中所使用的因素描述的对应关系，该对应关系详见 HeaderDataDictionary_v3.txt 文件中的表1与表2（以及表1和表S1……）
