fMRI BOLD Signal Changes During Strategic Social Interaction Game

Functional MRI data from 46 healthy adults performing a modified Rock-Paper-Scissors game and a control task. The dataset includes whole-brain analyses of neural activity and task-modulated functional connectivity in Theory of Mind brain regions. The study was authored by Maya Zheltyakova and uploaded to figshare in April 2026.

Use Cases

• Analyze BOLD signal increases in regions like the mPFC, TPJ, IFG, and precuneus during the Rock-Paper-Scissors task relative to a control condition.
• Examine task-modulated functional connectivity (TMFC) patterns, such as interactions between the bilateral TPJ and precuneus with the left IFG.
• Investigate negative BOLD deflections (deactivation) below baseline in regions like the midcingulate cortex and opercular regions during the strategic game.
• Compare the directionality of BOLD signal changes (increases vs. suppression) in canonical Theory of Mind regions between cognitive and affective task domains.

Strengths

• Data from 46 healthy adult participants provides a moderate sample size for fMRI research.
• The study design includes a control task condition, allowing for contrast-based analysis of task-specific neural activity.
• Analyses cover both neural activity (BOLD signal) and task-modulated functional connectivity (TMFC) across the whole brain.

Limitations

• The dataset is small at 2.3 MB, suggesting it contains summary results or a limited subset of the raw neuroimaging data.
• The sample consists of 46 healthy adults, which may limit generalizability to clinical populations or other age groups.
• Specific row counts, column names, and granular participant-level data are not provided in the description.
