BIDS-structured resting-state electroencephalography (EEG) data extracted from an experimental paradigm.

Electroencephalography (EEG) offers a unique window into the dynamics of the neuronal symphony that powers our brains. Here, we describe a publicly available dataset of EEG recorded from 111 healthy subjects. The data were recorded with 64 electrodes in a resting-state condition, an approach that offers broad-spectred analysis options, including functional connectivity and graph theory. In a subset of the subjects (n = 42), a second EEG recording was performed, 2-3 months after the initial recording, allowing measurement stability to be assessed. Furthermore, in connection with the EEG acquisition, a range of neuropsychological test scores were obtained for each subject. The dataset is comprehensive and organised according to the Brain Imaging Data Structure (BIDS) specification, providing a valuable starting point for both aspiring and experienced researchers in a range of fields, including cognitive neuroscience, data science, machine learning, and clinical neurophysiology.
