Brain-Creation: Prompt-Guided Mental Creation fMRI
Brain-Creation follows a visual imagination paradigm that separates perception, memory maintenance, prompt comprehension, mental creation, and behavioral report. The current release contains fMRI series for data loading, temporal alignment, and analysis workflows.
Dataset Overview
- Subject series: 6 (
sub-01tosub-06) - Design: 982 image indices, with 3 prompt conditions per image
- Total trials: 10,998
- Runs: 552 creation runs and 186 rest runs
- Files: 738 compressed NIfTI images and 738 JSON sidecars
- Total size: approximately 22.35 GB
Data Organization
Condition Assignment
- Subjects 1-3: each covers all 982 image indices and 2,946 conditions.
- Subjects 4-6: each covers 240 image indices and 720 conditions. Their image subsets are mutually disjoint.
Image indices are local design identifiers, not verified NSD image IDs. Stimulus images, prompt text, and trial-to-condition mappings are not included.

Filenames identify the subject, session, task, and run. Tasks are creation and rest, with run indices counted separately for each task within a session. Each image has a matching JSON sidecar containing timing, volume counts, and protocol settings. Naming uses BIDS-style fields; this is not a complete BIDS dataset.

Temporal Alignment and Trial Structure
Each trial lasts 24 seconds, corresponding to 12 volume intervals at TR = 2 seconds.
| Phase | Duration |
|---|---|
| Fixation | 2 s |
| Image perception | 4 s |
| Memory maintenance | 2 s |
| Prompt comprehension | 6 s |
| Mental creation | 6 s |
| Behavioral report | 4 s |
A standard creation run contains 20 trials, spanning 480 seconds / 240 volumes. The final creation run for each of subjects 1-3 contains 6 trials / 72 volumes. Each session has beginning and ending rest runs, each retaining 170 seconds / 85 volumes.
fMRI Specifications
- Spatial dimensions: 72 × 72 × 48 voxels
- Voxel size: 3 × 3 × 3 mm
- TR: 2 seconds
- Storage: NIfTI-1,
int16, intensity scale approximately 0.1 - Compression: gzip (
.nii.gz)
Important Notes
- The initial five volumes have already been removed. Do not discard them again.
- Creation files contain the complete trial sequence, including all six phases.
- The release includes BOLD files and run-level JSON only; event tables, behavioral data, anatomical scans, and analysis derivatives are not included.
- NiBabel reads
.nii.gzdirectly and applies NIfTI intensity scaling automatically.
