Hippocampal Threat Representation: Unthresholded fMRI Activation Maps from an Anxiety Task

Group-level results from a high-resolution fMRI study of 19 participants performing an approach-avoidance conflict anxiety task. The dataset includes unthresholded SPM activation maps from primary and secondary analyses using different smoothing kernels. The data was produced by researchers at the University of Zurich and is associated with a 2020 publication in the Journal of Neuroscience.

Use Cases

• Analyzing brain activation patterns related to threat probability (TP) and threat magnitude (TM) parametric modulators.
• Investigating the neural representation of action (approach/avoidance) in conflict scenarios based on the described parametric analyses.
• Comparing localization results between analyses using 8 mm and 4 mm FWHM smoothing kernels.
• Studying the interaction effects between action, threat probability, and threat magnitude on BOLD signal.

Strengths

• Includes data from a controlled fMRI experiment with 19 human participants.
• Provides results from multifold parametric analyses with serial orthogonalization of modulators.
• Contains both primary (8 mm kernel) and secondary localization (4 mm kernel) analyses.

Limitations

• Row count and specific file formats are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred from the description or original publication.
