EEG recordings from 10 BCI-naive participants acquired with a low-cost consumer-grade device during a motor imagery versus rest protocol. Participants performed kinesthetic imagination of a grasping movement with the dominant hand and rest/idle conditions across five runs, including an initial real-movement run. EMG of the dominant hand was recorded for protocol control, supporting evaluation of affordable brain-computer interface systems.

Resting-state EEG recorded at UC San Diego from patients with Parkinson's disease and healthy controls. Patients were recorded in two sessions, on and off dopaminergic medication, while controls completed a single session. The dataset includes participant demographics and UPDRS and MMSE clinical measures, and is curated in BIDS format for studying oscillatory and waveform characteristics of Parkinson's disease.

This dataset contains eyes-open resting-state EEG recordings from individuals with Parkinson's disease and healthy controls. It comprises 358 recordings from 312 participants, with some participants recorded across multiple sessions to allow longitudinal analyses. Participant demographics and session-level clinical measures (MoCA, UPDRS Part III, disease duration, levodopa equivalent daily dose) are provided alongside BIDS-formatted BrainVision data.

This dataset contains electroencephalography (EEG) recordings collected to study cortical contributions to feedback sensorimotor control during reactive balance. It accompanies a paper examining how cortical activity relates to balance responses following perturbations. The data are organized in BIDS format with HED annotations.

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.

This dataset contains simultaneously recorded EEG and fMRI data from 22 adults aged 23 to 51 years, collected at the Nathan Kline Institute while participants watched naturalistic video stimuli. It also includes eye tracking, physiological (respiration) recordings, demographic information, and behavioral measures such as sleep and caffeine intake. The goal is to investigate the relationship between electrical brain activity and hemodynamic fluctuations.

This dataset is a BIDS-formatted derivative of Study M from the bigP3BCI collection, a large open P300-based brain-computer interface resource. It contains 16-channel EEG recorded at 256 Hz from 21 participants using a 9x8 character speller grid with adaptive and checkerboard stimulus paradigms. Target and non-target events are annotated with HED tags, supporting machine-learning work on P300 speller classification.

Release 1 of HBN-EEG, the EEG component of the Child Mind Institute Healthy Brain Network (HBN) project, organized in BIDS format. It includes EEG recordings and behavioral responses from 136 participants aged 5-21 performing six passive and active tasks: resting state, surround suppression, movie watching, contrast change detection, sequence learning, and symbol search. Events carry HED annotations, and the participants file includes quality control results and CBCL-derived psychopathology factors.

Resting-state EEG dataset from 149 participants, including 100 individuals with Parkinson's disease and 49 controls. Recordings were acquired with a 64-channel BrainVision system during two minutes of eyes-open rest. The data support investigation of neural correlates of cognitive dysfunction in Parkinson's disease.
