Simultaneous EEG and fMRI recordings from healthy volunteers who reported their confidence in the accuracy of decisions they either committed themselves or merely observed. The dataset supports analysis of postdecisional contributions to metacognition and includes raw fMRI, BrainVision EEG, T1 anatomical scans and field maps, along with preprocessed EEG and fMRI derivatives.

Resting-state EEG recorded with a 128-channel EGI system from participants who also underwent structural MRI. The dataset was first reported in a study of whole-brain electrophysiological functional connectivity dynamics in resting-state EEG. Data were preprocessed with band-pass and notch filtering, artifact and bad-channel handling, average re-referencing, and downsampling to 250 Hz.

This EEG dataset contains recordings from two experiments in which participants listened to noise bursts presented from loudspeakers at different elevations in a hemi-anechoic chamber. Experiment 1 was a deviant detection task with adapter and probe sounds, and Experiment 2 was a one-back localization task. Participants first completed a behavioral test of their ability to localize elevated sound sources. The dataset supports research on how sound source elevation is encoded in human auditory cortex.

This derivative dataset repackages the public Dryad release accompanying Siebenhühner et al. (2020). It provides per-subject connectivity matrices computed from 10-minute resting-state SEEG (59 epilepsy patients) and MEG (19 healthy participants, plus a 10-participant eyes-open/eyes-closed cohort) recordings. The matrices cover phase synchrony (PLV, wPLI), cross-frequency phase synchrony, phase-amplitude coupling and amplitude-envelope coupling, each with surrogate values. Supporting files, neuropsychological scores and figure plot data are also included. Raw recordings are not included.

An EEG dataset paired with audio recordings for decoding speech from brain activity. It includes overt speech production, auditory listening, and listening followed by covert speech imagery tasks. Data were acquired with three EEG systems (g.tec g.Pangolin, g.tec g.SCARABEO, and ANT Neuro eego sports), together with EOG, EMG, and audio monitor channels.

Magnetoencephalography and anatomical MRI recorded from 10 participants during a passive hMT+ (human visual motion area) localizer task. Participants viewed random dot clouds that either stayed incoherent or turned coherent (up or down) after 500 ms. The data come from the vision-only training group of a study on supramodal processing, visual perceptual learning, and plasticity.

VEPCON is a multimodal BIDS dataset with high-density EEG, structural MRI and diffusion-weighted imaging from 20 participants. Visual evoked potentials were recorded during face versus scrambled-face discrimination and coherent versus incoherent motion discrimination. Derivatives include preprocessed single-trial EEG, FreeSurfer outputs, multi-scale brain parcellations (83 to 1015 regions), structural connectomes, and EEG source-imaging inverse solutions, supporting multimodal methods development and structure-function studies.

This dataset contains functional near-infrared spectroscopy (fNIRS) recordings collected during a word-color Stroop task using a sparse fNIRS montage. It accompanies a study comparing high-density, multi-distance fNIRS with sparse configurations for detecting task-related brain activity. The data are organized in BIDS format and are mirrored on NEMAR from OpenNeuro.

This dataset contains 64-channel EEG recorded from 31 healthy participants performing a two-class (left vs. right hand) motor imagery task. Each participant completed up to three sessions of 40 trials. The recordings are part of a multimodal collection that also includes eye-tracking and high-speed video, intended for analyzing ocular activity across BCI paradigms. Events are annotated with HED, and the data are organized in BIDS format via MOABB.

This dataset contains EEG recordings from phoneme discrimination tasks combined with transcranial magnetic stimulation (TMS) of the motor cortex. It merges two studies: a 2019 study of consonant-vowel and vowel-consonant pairs in 8 participants, and a 2021 study in 16 participants that added single phonemes, real words and pseudowords. It is intended to support research on speech decoding and the role of articulation and coarticulation in speech perception.
