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.

Microwire local field potentials (200 Hz) recorded from Behnke-Fried hybrid depth electrodes in 16 patients with drug-resistant epilepsy during a cognitive-boundary memory paradigm. Participants encoded 90 silent movie clips containing no, soft, or hard event boundaries, then completed a scene-recognition test and a time-discrimination test. Recording sites include the amygdala, hippocampus, and parahippocampal gyrus, with some participants also covering the dorsal anterior cingulate, pre-SMA, and ventromedial prefrontal cortex. This is an iEEG-BIDS representation of the authors' NWB release on DANDI (000940), supporting analyses of theta phase precession and episodic memory.

Preprocessed stereo-EEG (sEEG) recordings from 12 epilepsy patients reading 61 Chinese words aloud, packaged in BIDS from the Du-IN release (Zheng et al., NeurIPS 2024). The data are the authors' band-pass filtered, resampled, bipolar-referenced 3-second word-labelled epochs, stored back to back in BrainVision files, with word labels and English translations in the events files. The dataset supports research on speech decoding from intracranial neural signals.

Stereo-EEG recordings of non-REM (N2/N3) sleep at original sampling rates (512, 1024 and 2000 Hz) from 71 patients with drug-resistant focal epilepsy, released through the MNI Open iEEG Atlas. Only bipolar channels judged to show normal physiological activity in non-lesional grey matter are included (1152 channels), with Talairach coordinates and 17 brain-region labels. The data were used to derive normative values for ripples, fast ripples and high-frequency activity across brain regions.

AJILE12 is a long-term naturalistic intracranial dataset of electrocorticography (ECoG) recorded opportunistically from 12 epilepsy patients during clinical monitoring at Harborview Medical Center. Recordings cover 55 full monitoring days (days 3-7 after implantation) with simultaneous video, from which upper-body pose, validated wrist-movement initiation events and coarse behavioural state labels were derived. This iEEG-BIDS representation converts the original NWB release from DANDI without altering signal values.
