资源简介:
This dataset includes group-level results from multifold parametric analyses of a high-resolution fMRI approach-avoidance conflict anxiety task (n = 19). SPM Results are divided in primary analyses using a 8 mm FWHM smoothing kernel, and secondary (localization) anaylses using a 4 mm FWHM kernel.
Parametric modulators of BOLD activation were set up with serial orthogonalization in the following order: P1: TP, TM, TP x TM P2: A, TP, TM, A x TP, A x TM, TP x TM, A x TP x TM P3: Two separate analyses for approach and avoidance trials. Order of modulators as in P1.
Abbreviations: TP = threat probability TM = threat magnitude A = action (approach / avoidance)
The study is reported in the following reference: Abivardi A.*, Khemka S.*, Bach D.R. (2020) Hippocampal Representation of Threat Features and Behavior in a Human Approach-Avoidance Conflict Anxiety Task (accepted for publication in Journal of Neuroscience)

本数据集包含一项高分辨率功能磁共振成像(fMRI)趋近-回避冲突焦虑任务的多重参数分析组水平结果,共纳入19名被试(n=19)。统计参数映射(SPM)结果分为两类:采用8mm半高全宽(FWHM)平滑核的主分析,以及采用4mm平滑核的二次(定位)分析。
血氧水平依赖(BOLD)激活的参数调节因子采用序列正交化方式设置,顺序如下:
P1:威胁概率(TP)、威胁强度(TM)、TP×TM;
P2:行为反应(A,即趋近/回避动作)、TP、TM、A×TP、A×TM、TP×TM、A×TP×TM;
P3:针对趋近试次与回避试次的两项独立分析,调节因子顺序与P1一致。
缩写说明:TP=威胁概率(threat probability),TM=威胁强度(threat magnitude),A=行为(趋近/回避动作)。
