Electrophysiological dataset recorded from the amygdalae of nine epilepsy patients undergoing preoperative invasive monitoring in the mesial temporal lobe. Participants viewed dynamic visual sequences of fearful faces (aversive condition) interleaved with neutral landscapes (neutral condition). The dataset provides intracranial EEG in BIDS format, together with neuronal spike times and waveforms in NIX format, enabling study of amygdalar responses to aversive stimuli from macroscopic field potentials to single-neuron firing.

Raw intracranial EEG (iEEG) recordings from the PROBE study, collected from patients undergoing stereo-EEG monitoring under the DSI-SEEG protocol. The dataset also includes pre- and post-surgery structural MRI. It supports investigation of human cognitive and decision-making processes using intracranial recordings.

A multicenter collection of intracranial EEG (ECoG and SEEG) recordings from epilepsy patients at four clinical centers (NIH, JHH, UMMC, UMF), organized in BIDS. Recordings are snapshots around seizure events and include clinician annotations of seizure onset and offset, seizure onset zone, and resected or ablated contacts. The data support research on localizing the epileptogenic zone, including neural fragility analysis.

This dataset contains concurrent electrical stimulation and functional MRI (es-fMRI) recordings from 26 patients with medically refractory epilepsy who had intracranial electrodes implanted in cortical and subcortical sites. Selected electrode contacts were stimulated in a block design while whole-brain BOLD activity was recorded. The resource includes pre-operative and post-operative sessions, structural scans, resting-state scans, field maps, stimulation coordinates and parameters, and fMRIPrep and FreeSurfer derivatives.

EEG recordings from 20 healthy participants performing a tactile detection task with confidence ratings, plus ECoG from one patient with intractable epilepsy. The data were collected to study how evidence accumulation relates to perceptual consciousness and metacognitive monitoring. Near-threshold vibrotactile stimuli were delivered to the right wrist, with detection and confidence reports collected over 500 trials per participant.

This dataset contains independent 3-second single-channel intracranial EEG (stereo-EEG) clips from St. Anne's University Hospital (FNUSA), annotated for classification of physiological and pathological graphoelements and artifactual signals. It is a BIDS conversion of the segmented .mat archives released with Nejedly et al. 2020. Clips from one subject and one SEEG contact are concatenated per run at 5000 Hz, with events preserving labels, anatomy, reviewer, seizure onset zone flag, and electrode type.

A BIDS conversion of a multicenter intracranial EEG (iEEG) dataset of 3-second single-channel clips for classifying graphoelements (physiological and pathological activity) and artifactual signals. Clips were recorded from stereo-EEG contacts at 5000 Hz and concatenated into runs per subject and contact. Events preserve the original labels, segment IDs, anatomy, reviewer IDs, seizure onset zone flags, and electrode types.

De-identified intracranial EEG recordings from 58 patients undergoing surgical evaluation for drug-resistant epilepsy at the Hospital of the University of Pennsylvania. Recordings used subdural grid, strip, and depth electrodes (ECoG) or stereotactically placed depth electrodes (SEEG), and include interictal and ictal periods. The dataset provides electrode localizations in ICBM152 MNI space, clinically determined seizure onset channels, and channels overlapping the resection or ablation zone segmented from the resection cavity.

VocalMind is a stereotactic EEG (sEEG) dataset for speech decoding research in a tonal language (Mandarin Chinese). Intracranial recordings were acquired while a participant produced vocalized, mimed, and imagined speech. The data support research on speech brain-computer interfaces and neural decoding of overt and covert speech. This BIDS conversion contains one subject with three tasks corresponding to the speech modes.

The Brain Treebank is a large-scale dataset of intracranial (stereo-EEG) recordings from 10 epilepsy patients who watched Hollywood movies. Signals were sampled at 2048 Hz from 1,688 electrodes in total, across 26 movie trials and about 43 hours of data. The movie audio was transcribed with manually annotated word onsets, and each transcript was parsed into Universal Dependencies syntax trees. This makes the dataset a resource for studying the neural basis of naturalistic language. This record provides the data in BIDS-iEEG format.
