Whole-Head Cocktail Party fNIRS

NIRS

Whole-head functional near-infrared spectroscopy (fNIRS) recordings from 38 participants performing covert and overt spatial-attention tasks in a cocktail-party paradigm, with simultaneous eye tracking. The montage comprises 56 sources and 144 detectors, yielding 1134 measurement channels sampled at about 8.99 Hz. Tasks include overt and covert attention, a visual orienting baseline, resting state, and video-locked attention recordings.

EmoEEG-MC: A Multi-Context Emotional EEG Dataset for Cross-Context Emotion Decoding

BEH EEG Zarr

EmoEEG-MC is a multi-context emotional EEG dataset containing 64-channel EEG and peripheral physiological signals (PPG and GSR) from 60 participants. Emotions were induced in two contexts, video viewing and mental imagery, and covered seven categories: joy, inspiration, tenderness, fear, disgust, sadness and neutral. The dataset is intended to support cross-context emotion decoding, and SVM baselines with L1 regularization achieved above-chance accuracy for binary and seven-category classification.

Auditory Streaming and Interoception

EEG Zarr

EEG dataset on auditory streaming and interoception, collected at the University of Chicago and organized in BIDS format. The README gives few details of the experimental design, so the description rests mainly on the dataset name and metadata.

EMG Zarr

A BIDS-formatted high-density surface EMG (HDsEMG) dataset from 16 young volunteers performing submaximal (10-80% MVC) isometric ankle dorsiflexions (tibialis anterior, n=8) or knee extensions (vastus lateralis, n=8). Signals were recorded with four 64-electrode arrays (256 channels in total) together with force signals, supporting the decomposition of extensive motor unit samples and the study of rate coding. It is a BIDS conversion of the data from Avrillon et al. 2024, produced with the MUniverse software.

M3CV: Multi-subject, Multi-session, Multi-task EEG Database

EEG Zarr

M3CV is a multi-subject, multi-session, multi-task EEG database with 64-channel recordings from 95 healthy young adults. Each subject was recorded on two different days across six paradigms covering 13 distributed signal types: resting states, motor execution, transient visual, auditory and somatosensory responses, SSVEP, P300, SSAEP and SSSEP. The data were originally released for an EEG-based biometrics competition on Kaggle. This BIDS version reconstructs pseudo-continuous EEG from the distributed pre-epoched, preprocessed 250 Hz files.

Auditory-Visual Shift Study

EEG Zarr

This dataset contains EEG and EOG recordings from younger and older adults performing an interleaved auditory-visual dual-oddball attention-shift task. It was designed to examine how aging affects selective attention and responding to auditory versus visual stimulus streams. Participants performed focus-auditory, focus-visual, and shift-focus conditions, and the data are annotated with HED 8.0.0 in BIDS format.

Chang et al. 2025 — A multi-paradigm EEG dataset for studying upper limb rehabilitation exercises (Lanzhou Jiaotong University)

EEG Zarr

This dataset contains scalp EEG recordings from 28 participants performing or imagining upper-limb rehabilitation exercises under a multi-paradigm protocol. It is intended to support research on motor-imagery and rehabilitation brain-computer interfaces for restoring upper-limb function. The data are organized in BIDS format under a motor-imagery task.
