Stereo-EEG recordings from a single drug-resistant epilepsy patient with a right posterior temporal periventricular nodular heterotopia (PVNH). High-frequency (43 Hz) stimulation of the PVNH elicited autoscopic hallucinations, and single-pulse electrical stimulation was used to map effective connectivity. The dataset supports multi-modal connectivity analysis of the network involving the PVNH, occipital and temporal neocortex, fusiform gyrus and parietal cortex.

Subdural electrocorticography (ECoG) recorded at the University Medical Center Utrecht from three epilepsy patients (S4-S6) who imagined grasping a cylinder with the left or right hand. The data are the subset of participants from Stolk et al. (2019) who gave permission to share, and they support investigation of dissociated alpha and beta rhythmic activity in the human sensorimotor system. Data are released as unprocessed trial segments, stored as epoched recordings with electrode positions and author-provided atlas labels.

This BIDS derivative dataset provides sorted single-unit (microwire) recordings from the human medial temporal lobe (hippocampus, entorhinal cortex, amygdala) of nine patients with drug-resistant focal epilepsy performing a modified Sternberg verbal working memory task. It contains 1526 units with spike times per trial, mean and standard deviation waveforms, electrode and anatomical mapping, and trial properties. Subject, session and trial labels are aligned to OpenNeuro ds004752 / NEMAR on004752, which hosts the scalp and intracranial EEG of the same patients.

Processed 200 Hz derivative release of the MNI Open iEEG Atlas, providing artifact-free intracranial EEG (stereo-EEG and subdural strips/grids) from channels with normal activity in 106 patients with drug-resistant focal epilepsy. It includes one minute per vigilance state (wakefulness, N2, N3, REM) and up to 10 minutes of N2/N3 sleep, recorded as bipolar derivations with MNI-space electrode coordinates. The data serve as a normative atlas of physiological intracranial activity across cortical regions during wake and sleep.

Multichannel intracranial EEG (iEEG) recordings from 25 epilepsy patients during sleep, acquired at two medical centers (Tel Aviv Sourasky Medical Center and UCLA). The dataset includes 852 interictal epileptiform discharges, mainly from the medial temporal lobe, annotated by expert neurologists, and is provided in BIDS format. It supports development and benchmarking of automated interictal discharge detection methods.

Preprocessed intracranial EEG (ECoG and SEEG) from one epilepsy patient (SubjectUCI29) released with the FieldTrip human intracranial analysis protocol of Stolk et al. (2018). The data comprise 26 epochs of 152 channels sampled at 5000 Hz, aligned to target-tone onset in an auditory detection task with a button-press response. The epochs were demeaned, low-pass filtered and band-stop filtered by the original authors. The raw recordings were not shared, so the dataset is packaged as a BIDS derivative together with electrode coordinates.

Stereo-EEG recordings from 20 patients with pharmacoresistant epilepsy performing a sequential three-operand arithmetic task during presurgical evaluation. The deposit contains preprocessed, bipolar-referenced epochs (-2 to +7 s around the first operand, 512 Hz) from 1518 bipolar channels, with MNI contact coordinates. It supports analyses of the temporal order of activations and interactions in numerical cognition. It is released as a BIDS derivative of the authors' Zenodo deposit.

The Bern-Barcelona database contains 7500 pairs of intracranial EEG signals (3750 focal and 3750 non-focal) from five patients with pharmacoresistant temporal lobe epilepsy. Each pair consists of two neighbouring channels, recorded for 20 s at 512 Hz and drawn from seizure-free intervals, and the pairs have been used to study nonrandomness, nonlinear dependence and nonstationarity of EEG. This BIDS release is a lossless repackaging of the original published text files into BrainVision format. Patient identity is not retained, so all runs are pooled under a single pseudo-subject.

This dataset contains 300 single-channel intracranial EEG segments (23.6 s each, 173.61 Hz) from five epilepsy patients, corresponding to sets C, D and E of the Bonn EEG dataset of Andrzejak et al. (2001). Sets C and D are seizure-free interictal recordings from hippocampal formations (opposite hemisphere and epileptogenic zone, respectively), and set E contains ictal activity. The data are a lossless BIDS re-packaging of the published text files, pooled under a single pseudo-subject because segment-to-patient mapping is unavailable.

A calibrated task subset of Kai J. Miller's library of human electrocorticographic (ECoG) data, comprising 111 recordings from 24 epilepsy patients with subdural electrode grids. Tasks include finger flexion, hand gestures, motor movement and imagery, and verb generation and noun reading. Data were recorded at 1 kHz and converted to BIDS in BrainVision format with source-documented amplitude calibration.
