| # 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. |
