Brain-to-Brain Interface Data from 20 Questions Game

Andrea Stocco's dataset documents the first non-invasive brain-to-brain interface experiment using a 20 Questions game paradigm. It contains data from ten participants forming five inquirer-respondent pairs, who used EEG and TMS for real-time collaborative problem-solving. The data supports analysis of accuracy in identifying mystery items compared to a sham control condition.

Use Cases

• Analyze EEG and TMS signal patterns to decode successful versus unsuccessful collaborative trials across five participant pairs.
• Compare task accuracy metrics between the active brain-to-brain interface and the sham control condition.
• Model the interactive question-answering protocol to understand information transfer efficiency in real-time BBI communication.
• Investigate the role of steady-state visually evoked potentials in conveying consciously perceived visual stimuli between participants.

Strengths

• Dataset originates from a published, peer-reviewed study demonstrating the first non-invasive BBI for collaborative problem-solving.
• Includes data from ten participants across five distinct inquirer-respondent pairs for comparative analysis.
• Results show high levels of accuracy significantly greater than a sham control condition, providing a clear performance benchmark.
• Captures a novel interactive paradigm involving real-time, bi-directional information exchange between human brains.

Limitations

• The sample size is limited to ten participants, which may restrict the generalizability of statistical findings.
• Data specifics such as row count, column features, and file formats are not provided in the input, limiting immediate usability assessment.
• The experimental setup is highly specialized, requiring domain knowledge in EEG, TMS, and brain-computer interfaces for effective analysis.
