# NODEAP: Distinct contributions of anterior and posterior OFC to outcome-guided behavior **Summary** This dataset includes defaced anatomical T1-weighted MRI and raw multi-echo resting-state fMRI data from a study investigating the distinct roles of the anterior (aOFC) and posterior (pOFC) lateral orbitofrontal cortex in outcome-guided (goal-directed) behavior. Participants underwent odor–reward learning and outcome devaluation across multiple sessions. To probe causal contributions of OFC subregions, network-targeted TMS was applied to either aOFC or pOFC in separate sessions, and its effects on learning versus inference were assessed. - For project code, behavioral data, and full analysis pipelines (including preprocessing of multi-echo resting-state fMRI), see: 👉 [project-nodeap-core](https://github.com/QingfangLiu/project-nodeap-core) - For standalone analyses using functional connectivity derived from this dataset with deep learning methods (e.g., CVAEs), see: 👉 [project-nodeap-fmri-cvae](https://github.com/QingfangLiu/project-nodeap-fmri-cvae) **Participants** - N = 48 healthy adults - See `participants.tsv` for sex, age, stimulation group (aOFC vs. pOFC), and counterbalanced TMS and meal orders **Sessions / tasks** Each subject may have several MRI sessions; session labels match the original collection schedule: - `ses-D0` – baseline/resting-state MRI (no devaluation). - `ses-S1D1`, `ses-S1D2`, `ses-S2D1`, `ses-S2D2`, `ses-S3D1`, `ses-S3D2` – study days spanning learning (Day 1) and post-meal devaluation/choice (Day 2). Some sessions include network-targeted TMS (aOFC or pOFC). - Functional scans are resting-state; multi-echo acquisitions are provided as separate echoes. **What’s included** - `sub-*/anat/` - Defaced T1w MRI: `sub-XX_T1w.nii.gz` (+ JSON sidecar if available). - `sub-*/ses-*/func/` - Raw multi-echo BOLD: `sub-XX_ses-YY_task-rest_run-01_echo-{1,2,3}_bold.nii.gz` (+ matching JSON sidecars when available). - Top-level: `dataset_description.json`, `participants.tsv`, `participants.json`, `README.md`. **Notes on data quality & privacy** - T1w images were defaced prior to sharing. - Functional files are raw (converted with dcm2niix); files with SPM-style prefixes (r/w/y/s*) were excluded. **Folder conventions (BIDS)** ``` nodeap-bids/ sub-01/ anat/sub-01_T1w.nii.gz ses-D0/func/sub-01_ses-D0_task-rest_run-01_echo-1_bold.nii.gz ses-D0/func/sub-01_ses-D0_task-rest_run-01_echo-2_bold.nii.gz ses-D0/func/sub-01_ses-D0_task-rest_run-01_echo-3_bold.nii.gz ses-S1D1/func/... sub-02/ ... ``` **How to cite** Please cite our paper: Liu et al., 'Distinct contributions of anterior and posterior orbitofrontal cortex to outcome-guided behavior', Current Biology (in press).
