This dataset is the EEG and structural MRI portion of a multi-subject, multi-modal face processing study (originally ds000117), repackaged in EEGLAB format with augmented event logs and HED annotation. Eighteen participants viewed famous, unfamiliar, and scrambled faces while making symmetry judgments. The original study had two sessions (fMRI and simultaneous MEG/EEG); only the MEEG session's EEG data and the structural MRI are included here, while MEG and fMRI data are excluded. Minimal preprocessing, including EEG channel extraction, event correction, and resampling to 250 Hz, yields a lightweight version suitable for tutorials and EEG source localization.

Raw multimodal recordings of 18-channel EEG and functional near-infrared spectroscopy (fNIRS) from seven participants with orthopedic impairment performing motor imagery tasks. Each participant completed three sessions of 40 trials, with four motor imagery tasks (reach, twist, lift, grasp) presented in random order. The dataset supports research on multimodal brain-computer interfaces for people with motor impairments.

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.

This dataset contains magnetoencephalography (MEG) recordings from seventeen adult participants who completed a learning task and a resting-state condition. Data were acquired on a 4D NeuroImaging system with 248 magnetometer channels. The same participants performed an identical learning task during fMRI scanning, released as a companion dataset. The task involved the production of phonotactically legal and illegal pseudowords.

EEG dataset from 19 participants performing a visual P300 speller-like paradigm to assess how visual stimulus properties affect evoked responses and classification accuracy. Each participant completed three sessions with conditions varying the number of stimuli (4 to 9) and the flash type (standard flash versus a superimposed yellow smiling cartoon face). Recordings comprise 382 files from eight electrodes sampled at 256 Hz, with markers encoding trial phases and activated symbols.
