This is the data used for the following study: Folders are organized in BIDS format. Within each subject folder (e.g. /sub-01/) there are subfolders with the following: Ses-first/ a) beh - Behavioral results from first session outside the scanner conditioning (event.tsv) - Instrumental conditioning - Pavlovian Conditioning - Hedonic evaluation of stimuli ses-second/ 1) anat - structural whole brain T1-weighted (T1w) images (isotropic voxel size = 1.0 mm) defaced 2) func - contains the raw BOLD timeseries (26 partial oblique axial T2*weighted EPI) with its associated behavioral data (event.tsv) used for the analysis. - PIT task, with odors as stimuli and uses a hand dynamometer to measure mobilized effort. - HEDONIC task, with odors as stimuli and uses visual analog scales to measure subjective liking and intensity ratings. 3) fmap - Dual gradient B0 field maps (Fmaps) used for preprocessing Please note that you can find the preprocessed functional MRI data (smoothed and unsmoothed) used for our analysis into the /DERIVATIVES/PREPROC folder. Also note that not all participants finished all tasks, or scans. See paper for a description.
