Ultra high-density 128-channel EEG recorded from 18 individuals with migraine (interictal) and 21 healthy controls. Recordings include steady-state visual evoked potential (SSVEP) and steady-state auditory evoked potential (SSAEP) tasks at 4 and 6 Hz, as well as eyes-open resting state. The data support analyses of cortical coherence abnormalities in migraine.

EEG recordings from two tetraplegic pilots of team Brain Tweakers (CNBI, EPFL) during longitudinal motor-imagery BCI training for the Cybathlon 2016 BCI race. The dataset contains 16-channel EEG from cue-based offline calibration runs with three classes (both hands, both feet, rest), recorded at 512 Hz. It was re-released in BIDS format from the original Zenodo deposit via MOABB.

Motor-imagery EEG recorded from 12 healthy, BCI-naive participants performing cued left- versus right-hand imagery to control a Baxter robot arm reaching toward objects. Each participant completed three sessions with first-person and third-person visual feedback conditions, giving 480 trials per subject. Data were recorded with a 32-channel LiveAmp system at 250 Hz and re-released in BIDS format via MOABB.

EEG recordings from 47 neurotypical children and adolescents (5-18 years) who each completed a two-stage SSVEP-based brain-computer interface session. The session comprised a stimulus personalization pipeline followed by an online 4-target SSVEP game. Data were recorded with a 16-channel g.tec gel-based system at 256 Hz. The dataset was released by the BCI4Kids program to support signal-processing methods developed specifically for pediatric SSVEP-BCI data.

Derivative dataset of intracranial current source density (CSD) traces from a single 20-year-old patient with drug-resistant epilepsy, comprising 18 seizure segments and 16 interictal segments. CSD was computed by the data authors from subdural ECoG at four sites (fronto-lateral Fl1 and Fl2, inferior-parietal iP, and fronto-basal Fb) and converted to BrainVision format. The data were used to demonstrate causal inference between dynamical systems in epileptic activity (Benkő et al., arXiv:1808.10806). The mapping of the contact names in the files (GrB6, GrE2, GrF4, FbB3) to the paper's region labels is not stated by the source and remains uncertain.

Derivative stereo-EEG dataset of high-frequency activity (HFA, 70-150 Hz) recorded from six patients with depth electrodes performing an approach-avoidance decision task. It supports analysis of the differential contributions of medial and lateral orbitofrontal cortex to decision-making under conflict. The data are the authors' processed HFA, epoched per trial and aligned to trial onset and decision, and are accompanied by per-trial behavioural data and artifact-review labels.

Stereo-EEG depth recordings from 11 patients with medically refractory temporal lobe epilepsy, collected at Sanbo Brain Hospital in Beijing. Recordings cover learning of object-location associations and targeted memory reactivation (TMR) with sounds during NREM sleep. The data were used to study electrophysiological signatures of variability in human memory consolidation. They are re-packaged in iEEG-BIDS from the authors' Zenodo release without filtering, resampling or re-referencing.

Stereo-EEG recordings from 10 Dutch-speaking patients with pharmaco-resistant epilepsy who read aloud 100 Dutch words presented one at a time on a laptop screen. Intracranial EEG (1103 recorded contacts spanning cortical and subcortical structures) was recorded simultaneously with the participants' pitch-shifted speech audio. The dataset supports research on speech production and speech decoding for brain-computer interfaces, and includes electrode localisations and FreeSurfer derivatives.

Intraoperative recordings from a single Neuropixels 1.0 silicon probe (384 sites) inserted into human cortex during neurosurgery at Massachusetts General Hospital. Three participants were recorded without a task, in prefrontal cortex during DBS lead implantation and in anterior temporal lobe during lobectomy. This release contains only the local-field-potential band (0.5-500 Hz, 2.5 kHz), losslessly converted from the DANDI NWB files into iEEG-BIDS (BrainVision) format.

Microwire local field potentials (400 Hz) from Behnke-Fried hybrid depth electrodes in 35 patients with drug-resistant epilepsy, recorded during a picture-based Sternberg working-memory task with load 1 or load 3. Recording sites include the hippocampus, amygdala, dorsal anterior cingulate cortex, pre-supplementary motor area and ventromedial prefrontal cortex. This is an iEEG-BIDS representation of the NWB data released on DANDI (000673) from the Daume et al. 2024 study, with signal values unchanged.
