EEG recordings from an auditory oddball task collected at the Meditation Research Institute in Rishikesh, India. Participants completed three sessions of a P300 paradigm with standard tones, oddball tones and white-noise distractors while sitting with their eyes closed in a darkened room. The dataset supports research on auditory event-related potentials and attention.

A large EEG database from 87 healthy participants recorded during a single-day motor imagery brain-computer interface (BCI) experiment. The data are organized into three datasets (A, B, C) that share one Graz-protocol task, left- versus right-hand motor imagery, with 240 trials per participant (over 20,800 trials in total). It also provides demographic, personality and cognitive-trait information, which supports studies of how user profiles relate to BCI performance and cross-user classification algorithms.

ERP CORE (Compendium of Open Resources and Experiments) is an open resource of raw EEG recordings from 40 neurotypical adults performing six optimized task paradigms. The paradigms elicit seven widely used ERP components: N170, MMN, N2pc, N400, P3, LRP and ERN. The dataset includes event code schemes, task stimuli for the N170, MMN and N400 paradigms, and participant demographics.
