Brain Co-Activation Patterns from Targeted VLPFC Stimulation During Emotional Film Viewing

A study of 99 healthy participants investigated state-dependent neuromodulation by repetitive transcranial magnetic stimulation (rTMS). Participants were allocated to active rTMS with sad film viewing, active rTMS with neutral film viewing, or sham rTMS with sad film viewing groups. The analysis calculated the fraction of time, resilience, and transition probabilities of four recurring co-activation patterns (CAPs) to characterize brain dynamics.

Use Cases

• Analyzing state-dependent effects of neuromodulation based on emotional context during stimulation.
• Investigating changes in brain network engagement based on co-activation pattern (CAP) metrics like fraction of time and resilience.
• Modeling transitions between brain functional states based on transition probabilities between identified CAPs.
• Comparing the effects of active versus sham stimulation on frontoparietal, default mode, visual, somatomotor, and salience network activity.

Strengths

• Data originates from a controlled experiment with 99 healthy participants across three distinct intervention groups.
• Analysis identified four recurring co-activation patterns (CAPs) with specific network characterizations.
• Dataset is licensed under CC-BY-4.0, facilitating open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a 4.1 MB DOCX document, which may require extraction of underlying data.
