Hippocampal Representation of Threat Features and Behavior in a Human Approach-Avoidance Conflict Anxiety Task: Unthresholded SPM Activation Maps

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)
