Abstract:
This dataset provides high-temporal-resolution electroencephalography (EEG) recordings collected from eight healthy adults during two conditions: (1) eyes-open resting state and (2) localized visual stimulation using a static, sector-shaped checkerboard presented in the lower-left visual field. EEG was recorded at 10,000 Hz in DC mode using a 64-channel actiCAP slim system (BrainProducts GmbH) and Bittium NeurOne Tesla amplifiers. All recordings are organized according to the Brain Imaging Data Structure (BIDS v1.9.0) and distributed as raw BrainVision files with complete metadata. The dataset includes behavioral responses for target-dot detection and detailed event annotations for each contrast level. Example preprocessing and analysis scripts are provided in MNE-Python to facilitate reproducible event-related potentials (ERPs) and time-frequency analyses. These high-sampling EEG recordings allow investigation of early visual evoked potentials, oscillatory phase alignment, and hemispheric lateralization under localized visual stimulation.
