This dataset contains behavioral events and electrophysiological (EEG) recordings from a hybrid spatial-navigation and free recall experiment in which participants act as couriers delivering items to stores in a virtual town and later recall their deliveries. Sessions were either read-only, used to collect training data, or closed-loop, in which classifier predictions of memory encoding were used to time stimulus presentation. It represents the non-invasive portion of a project aimed at improving memory through closed-loop stimulus timing optimization.

Release 7 of the HBN-EEG dataset, the EEG component of the Child Mind Institute Healthy Brain Network project, organized in BIDS format. It contains EEG recordings and behavioral responses from 381 participants aged 5-21 performing three passive tasks (resting state, surround suppression, movie watching) and three active tasks (contrast change detection, sequence learning, symbol search). Events carry HED annotations, and participants.tsv includes quality-control results and psychopathology factors derived from the CBCL questionnaire.

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.

Resting-state EEG recorded from 25 patients with Parkinson's disease enrolled in a double-blind, randomized, placebo-controlled trial of Neuroepo, an erythropoietin formulation with low sialic acid content. Participants received Neuroepo (n=15) or placebo (n=10), and EEG was recorded before and six months after administration. Raw data are provided in EEG-BIDS format to support assessment of qualitative and quantitative EEG (source-level) biomarkers of neuroprotection.

FOODEEG is an open dataset of electroencephalographic (EEG) and behavioural responses to food images from 117 participants. In one session, EEG was recorded during a food categorisation task in which participants judged images as healthy, tasty, or something they were willing to eat. In a second session, participants completed a food go/no-go task, a paired choice task, and questionnaires on dietary style and motivation. The dataset also includes raw and cleaned EEG data and normative ratings of the food stimuli from online samples.

EEG recordings from healthy participants performing self-initiated palmar and lateral reach-and-grasp actions, acquired simultaneously across three recording systems: gel-based laboratory EEG, water-based mobile EEG, and dry-electrode mobile EEG. The dataset supports investigation of the feasibility of decoding natural reach-and-grasp movement-related cortical potentials across EEG acquisition modalities for brain-computer interface applications. It is distributed in BIDS format as part of the MOABB benchmark collection.

A mobile EEG dataset on auditory attention recorded from 20 participants. Using a two-competing-speaker paradigm, participants either sat on a chair or walked a route indoors while attending to one speaker. Attention was disrupted by salient environmental events presented from in front of the participant, allowing study of neural tracking of speech in realistic, mobile conditions.

Release 9 of the HBN-EEG dataset, the EEG component of the Child Mind Institute Healthy Brain Network project, organized in BIDS. It contains EEG recordings and behavioral responses from 295 children and adolescents (ages 5-21) performing three passive tasks (resting state, surround suppression, movie watching) and three active tasks (contrast change detection, sequence learning, symbol search). Events carry HED annotations, and participants.tsv provides quality-control results and psychopathology factors derived from the CBCL, supporting research on pediatric mental health.

EEG dataset from a single healthy young adult examining how auditory, visual, and combined audio-visual stimulation entrain gamma-band brain oscillations. Gamma entrainment has been proposed as a therapeutic approach for Alzheimer's disease symptoms. The session consists of three 40-second stimulation epochs, using a 40 Hz amplitude-modulated auditory tone, a 20 Hz LED flicker, and both together.

This dataset contains EEG recordings from 127 young adults (18-30 years) together with retrospective indicators of childhood family socioeconomic status (SES) and adult SES measures, including education, income, food security, and home and neighborhood characteristics. EEG was recorded during ERP CORE tasks or adaptations of them, which target perception, cognition, and action. The dataset also includes an adult ADHD symptoms checklist, so that links between SES, ADHD symptoms, and neural activity can be examined in a socioeconomically diverse sample.
