Three-ball cascade juggling as a new paradigm to study complex motor execution using mobile brain-body imaging (EEG)

This dataset includes EEG recordings, motion capture marker positions, and ball trajectory data collected during three-ball cascade juggling. Motion capture provides 3D coordinates of markers, and ball data include trajectories, hand-hold status for each ball, and event information with labels, time indices, and ball identity. EEG is stored in EEGLAB format. All data were collected with informed consent under approved ethical procedures.

## Description of the data and file structure

This dataset contains EEG, motion capture, and ball trajectory recordings collected while participants performed three-ball cascade juggling. Motion capture provides 3D marker positions, ball data include trajectories, hand-hold status, and event timing for each ball, and EEG is stored in EEGLAB format.
