The PRIOS dataset contains electrocorticography (ECoG) recordings from 6 patients aged 13-53 years. Cortico-cortical evoked potentials (CCEPs) were elicited by single pulse electrical stimulation (SPES), both in the awake patient during clinical routine and under general propofol anesthesia in the operating room. The data support investigation of how propofol affects local effective brain networks.

This dataset contains cortico-cortical evoked potentials (CCEPs) recorded with electrocorticography (ECoG) during single pulse electrical stimulation in 74 patients aged 4-51 years. It was collected at the University Medical Center Utrecht as part of the RESPect epilepsy surgery registry and supports investigation of how signal transmission speed in the human brain develops with age. Data are organized in BIDS with electrode positions labeled by Destrieux atlas and transformed to MNI152 space.

Intracranial EEG (ECoG) recordings from 14 epilepsy patients implanted with clinical surface and depth electrodes, with two patients also carrying high-density research grids. Participants viewed grayscale pattern stimuli and color images of several categories. Stimuli varied in spatial and temporal properties, including pRF mapping bars, spatial and temporal patterns, and six-category localizers. Pre-implantation T1 MRI, FreeSurfer surface reconstructions and derivative broadband and preprocessed data are included.

Intracranial recordings from rat somatosensory cortex using the DISC (Directional and Scalable depth array) electrode array. Recordings were acquired under anesthesia while individual whiskers were stimulated with an air puffer, with each task name corresponding to the identity of the stimulated whisker. The dataset supports validation of the DISC array for sensing local field potentials.

A multicenter dataset of interictal intracranial EEG (iEEG) recordings from de-identified epilepsy patients, with sleep or awake state annotated where available. Data come from NIH, Johns Hopkins Hospital and University of Miami Jackson Memorial Hospital, and include patients treated with resection/ablation or responsive neurostimulation (RNS). Derivatives include source-sink connectivity analyses and high-frequency oscillation (HFO) detections using RMS and Hilbert detectors.

A clinical intracranial EEG (iEEG) dataset from 12 epilepsy surgery patients drawn from the RESPect (Registry for Epilepsy Surgery Patients) collection at the University Medical Center Utrecht. It includes six intraoperative ECoG recordings and six long-term recordings (three ECoG, three SEEG). The data are organized in BIDS, with session and run conventions that capture the surgical stage or the monitoring day and time, and the task labels describe the patient's state.

Clinical intracranial EEG (iEEG) recordings from 12 epilepsy surgery patients at the University Medical Center Utrecht, forming part of the RESPect (Registry for Epilepsy Surgery Patients) collection. Six patients were recorded intraoperatively with acute ECoG and six had long-term monitoring (three with ECoG, three with SEEG). The data are organized in BIDS, with separate session and run conventions for intraoperative and long-term recordings.

This dataset contains intracranial EEG (iEEG) recordings from one patient undergoing single pulse electrical stimulation at the Mayo Clinic. It was collected to study the effects of electrical stimulation on human brain networks, and it supports a larger effort to build a database of single pulse stimulation data for understanding the human connectome across the lifespan. The data accompany a paper on basis profile curve identification.

An open multimodal dataset combining intracranial EEG (electrocorticography and sEEG) and fMRI recorded during naturalistic stimulation with a short audiovisual film. Recordings were collected from patients at UMC Utrecht, and the dataset supports research on brain responses to naturalistic audiovisual input and on multimodal comparison of iEEG and fMRI signals.

This dataset contains interictal intracranial EEG (iEEG) recordings acquired during slow-wave sleep from 20 epilepsy patients, with annotated high-frequency oscillation (HFO) events (ripples, fast ripples, and combined events). It was converted to BIDS from the original publication's data, and the HFO markings are stored in per-run events files. The dataset has been used to validate HFO detection algorithms.
