EEG recordings from 100 healthy adults collected to study hemispheric asymmetries, specifically the relationship between N1 lateralization and alpha asymmetry. Each participant completed an eight-minute resting-state session with alternating eyes-open and eyes-closed periods. They then completed four lateralized visual tasks (words, faces, emotions, houses) with left- and right-hand responses.

EEG recordings from participants performing a rapid go/nogo visual task in which briefly flashed (20 ms) natural photographs had to be either categorized (animal vs. non-animal) or recognized (a previously learned probe image). Data were collected over two recording days, in series of 100 images with equally likely target and non-target trials. The dataset supports research on the timing of visual categorization and recognition processes and on single-trial EEG dynamics.

EEG dataset of a visual oddball (P300) task from the PURSUE project, collected in 2017 and 2018 from participants at three primarily undergraduate institutions in Southern California, Massachusetts, and Virginia. The task design follows the ERP CORE paradigm, and the dataset includes participant demographic information such as race.

Mobile EEG dataset from 18 participants performing tasks outdoors: resting eyes open/closed, an auditory oddball task while standing, walking alone, or walking with an experimenter, and walking-together conditions (natural, blinded control, synchronized). Each participant was recorded twice, once with active and once with passive electrodes, in counterbalanced order. The dataset supports comparison of electrode types and study of EEG during real-world walking and interpersonal step synchronization.
