Paranoia

Naturalistic fMRI dataset: 22 subjects listened to a three-part ambiguous social narrative (~22 minutes total) designed to elicit varying levels of paranoid interpretation. TR = 1.0 s. 3-second fixation before each run.

This repo mirrors the fmriprep-preprocessed dataset originally distributed via DataLad at https://gin.g-node.org/ljchang/Paranoia. fmriprep version 1.2.6-1.
