Summary
This study introduces a new dataset combining high-density Electroencephalography (HD-EEG) and mouse-tracking to explore brain decision-making dynamics. The resource aids research in neuroscience and brain-computer interfaces (BCI).
Area of Science:
- Neuroscience
- Cognitive Science
- Biomedical Engineering
Background:
- Understanding the neural basis of decision-making is crucial for both basic science and clinical applications.
- Existing datasets often lack the temporal resolution or multimodal integration needed to fully capture dynamic choice processes.
- Simultaneous recording of brain activity and fine motor responses offers a unique window into cognitive processes.
Purpose of the Study:
- To present a novel, publicly available dataset integrating high-density Electroencephalography (HD-EEG) and mouse-tracking.
- To provide a resource for investigating the dynamic neural mechanisms underlying semantic judgments and preference choices.
- To facilitate advancements in neural signal processing for decision neuroscience and brain-computer interface (BCI) development.
Main Methods:
- Acquisition of 128-channel HD-EEG and detailed mouse-tracking data from 31 healthy adult participants (ages 18-33).
- Inclusion of both resting-state and task-related paradigms, specifically food preference choices and semantic judgment tasks.
- Preliminary analysis including microstate analysis of resting-state EEG and event-related potentials (ERPs), topomaps, and time-frequency maps for task data.
Main Results:
- The dataset combines high-density EEG with precise mouse-tracking, capturing neural and behavioral dynamics during decision-making.
- Preliminary analyses demonstrate the feasibility of extracting meaningful neural signatures (microstates, ERPs, time-frequency patterns) related to choices.
- The integrated data allows for the examination of temporal dynamics in binary choices, including hesitation periods.
Conclusions:
- This multimodal dataset offers a valuable resource for studying the neural underpinnings of human decision-making.
- The combination of HD-EEG and mouse-tracking is poised to advance the understanding of cognitive processes and motor control.
- The dataset will support the development of novel algorithms for neural signal processing and enhance brain-computer interface applications.
