About This Dataset#
Intracranial EEG of 3 patients with treatment-resistant epilepsy (UCSF, under the care of Dr. Edward Chang) who
experienced immersive virtual-reality (VR) stimuli: a modified virtual-heights stimulus, a “no heights” baseline in VR and (two patients) a 360° shark movie, with simultaneous skin conductance and eye/visual-scanning measures.
This is the iEEG part of the release “Human Responses to Visually Evoked Threat” (Dryad doi:10.5061/dryad.wdbrv15mq,

Human Responses to Visually Evoked Threat — intracranial EEG (3 patients)
Overview
Reference article: Yilmaz Balban M, Cafaro E, Saue-Fletcher L, Washington MJ, Bijanzadeh M, Lee AM, Chang EF, Huberman AD (2021). Human Responses to Visually Evoked Threat. Current Biology 31(3):601–612.e3. https://doi.org/10.1016/j.cub.2020.11.035 (author manuscript: PMC8407368). Data and analysis code: Dryad doi:10.5061/dryad.wdbrv15mq.
Participants / cohort
Three patients with treatment-resistant epilepsy implanted with intracranial electrodes for localisation of seizure foci,
recorded at the UCSF Hospital (under the care of Dr. Edward Chang); they were included if they had electrodes in the regions
of interest (insula, orbitofrontal cortex) and were willing to do the VR task; implantation was guided solely by clinical
decision (paper, STAR Methods). participants.tsv gives, per patient, age, gender, STAI state/trait and GAD-7 from Table S1
of the paper (EC192: M, 33 y; EC200: M, 23 y; EC205: F, 44 y); the patient labels (EC 192, EC 200, EC 205) are identical in
the release folders and in the paper. Electrodes: EC192 and EC205 depth electrodes; EC200 a 64-contact grid and strips.
Electrodes in insula (EC192, EC205) and orbitofrontal cortex (EC200, EC205) were the focus of the paper. Further columns: implant type, number of electrode leads and implanted hemisphere (right for all three; derived from the release electrode tables), the paper’s regions of interest, the number of visual scanning episodes during heights reported in the paper (EC192: 3, EC200: 0, EC205: 2), and the year-month of the TDT iEEG exports (MAT-file headers: 2019-02, 2019-05, 2019-08; the recordings took place on or before these months, exact dates are not documented).
The healthy and anxious VR participants of the paper (no iEEG) are not part of this dataset.
Tasks
task-heights: modified heights stimulus, adapted to the patients’ mobility constraints: seated in a chair in a virtual copy of their hospital room, playing the ‘lights-out’ task (4 × 4 light grid; clicking a light toggles it and its neighbours, goal: all lights off) in front of them; 1 min into the task the walls and the floor of the virtual room fall away, leaving the subject seated on a platform of a building 50 stories high. iEEG covers 5 min before the stimulus (“No Visual Stim”) and the stimulus. (The healthy-participant version with a narrow plank ~150 ft above ground that had to be crossed is described in the paper but is not the patients’ version.)task-noheights: “No Heights” baseline: 5 min in the virtual hospital room without the heights stimulus, measured before the heights stimulus (paper, Modified Heights Stimulus); release fileTDTData_B*_baseline(EC205:baselineinVR).task-sharks: 360° movie of swimming with great white sharks (filmed at the Guadalupe Island field station), presented on the inner surface of a virtual sphere (EC192, EC205; Figure S5).
VR: Unity-programmed stimuli shown in an HTC Vive headset (secured with a custom Velcro cap); skin conductance was recorded simultaneously with the iEEG (paper).
Acquisition
Tucker-Davis Technologies PZ2 (256-ch) or PZ5 (512-ch) amplifier with an RZ2 acquisition system, 3051.7578 Hz. The VR headset was secured with a custom Velcro cap. Reference and ground not documented in the release. Electrode localisation in the paper: pre-operative 3T T1 MRI co-registered with post-operative CT (SPM12), confirmed by a neurologist; pial surfaces reconstructed with FreeSurfer.
Preprocessing already applied by the source
None: the release holds the raw TDT exports. The paper’s analysis steps (downsampling to 400 Hz, notch at 60/120/180 Hz, common average reference per lead, exclusion of noisy channels/epochs) were NOT applied to these data.
What was converted, and how
Each
TDTData_B<block>_<condition>.mat(MATLAB 7.3) holds the iEEG array (rawDataorData; where both exist they were verified identical), its sampling rate, andANIN(4 analog inputs at 24414.0625 Hz). The iEEG array (channels × samples, float64, volts) was written as BrainVision IEEE float32 in V (file value = stored value rounded to float32). No filtering, resampling, re-referencing or channel removal; all 128 (EC192, EC200) / 64 (EC205) inputs kept.Channel names: the release gives no channel labels; channels are
ch001…in array order. The electrode tables of the release (<EC n>_TDT_elecs_all_warped.mat: 94 / 100 / 52 rows, name, long name, type, anatomical label, xyz) are provided aselectrodes.tsv(space-Other) with the row number, but the mapping of TDT inputs to electrode rows is not documented, so no link between channels and electrodes is asserted. Channeltypeis the patient’s implant type. Rows whose name and type areNaNin the release (EC192 rows 31, 32, 63, 64; EC205 rows 31, 32; all with the same dummy position) are listed asunlabeled_row<k>with n/a coordinates. (Observation only: such placeholders at positions 31–32 and 63–64 are consistent with rows following amplifier-input order, but the release does not state it.)Events: the release holds per-condition
syncOnTimeandgsrshift/GSRsynctimevalues used by the authors’AACorrGSR_stanford.mto time-lock iEEG and skin conductance, and visual-scanning vectors (VS_heights, 1 value per second). Their time origin is not documented precisely enough to place them on the iEEG time axis, so noevents.tsvis generated; the files are insourcedata/.sourcedata/zenodo-4283021/: the iEEG folder (TDT files incl. ANIN, skin-conductance arrays, sync times, visual scans, analysis code), the electrode-location folder and the release read-me, extracted from the zips (macOS__MACOSXand.DS_Storeentries dropped). In every.mat, only the day in the MAT-file header text “Created on: …” was masked to01(weekday---); SHA-256 of original and public bytes are insourcedata/b2zen_provenance_IEEG044.json.Not included: the healthy/anxious VR participants’ data (gaze, game, physiology, survey; no iEEG) — their session logs contain real session date-times. They are available from the CC0 source record.
Known caveats (summary)
Channel-to-electrode mapping is not documented (see above); channel names are
ch001….No
events.tsv(time origin of the sync values not documented).Units: volts as stored in the TDT export.
In
electrodes.tsvof EC205 thegroupvalueOFCcovers three 10-contact leads (OFC11–OFC110, OFC21–OFC210, OFC31–OFC310);iEEGElectrodeGroupsandn_electrode_leadscount them separately.The paper’s Results text refers to EC 200 as “her”, while Table S1 lists EC 200 as M;
participants.tsvkeeps Table S1.Earlier versions of the
*_ieeg.jsonTaskDescription described the heights task with the healthy-participant plank and the no-heights run as the healthy-participant control; both were corrected on 2026-10-07 per the paper’s “Modified Heights Stimulus” section.

- save(path: str, overwrite: bool = False, offset: int = 0)[source]#
Save datasets to files by creating one subdirectory for each dataset:
path/ 0/ 0-raw.fif | 0-epo.fif description.json raw_preproc_kwargs.json (if raws were preprocessed) window_kwargs.json (if this is a windowed dataset) window_preproc_kwargs.json (if windows were preprocessed) target_name.json (if target_name is not None and dataset is raw) 1/ 1-raw.fif | 1-epo.fif description.json raw_preproc_kwargs.json (if raws were preprocessed) window_kwargs.json (if this is a windowed dataset) window_preproc_kwargs.json (if windows were preprocessed) target_name.json (if target_name is not None and dataset is raw)
- Parameters:
path (str) –
- Directory in which subdirectories are created to store
-raw.fif | -epo.fif and .json files to.
overwrite (bool) – Whether to delete old subdirectories that will be saved to in this call.
offset (int) – If provided, the integer is added to the id of the dataset in the concat. This is useful in the setting of very large datasets, where one dataset has to be processed and saved at a time to account for its original position.
