Intracranial EEG (stereo-EEG) recordings from 22 patients with drug-resistant epilepsy undergoing presurgical evaluation, capturing responses to 115 high-frequency intracranial electrical stimulations that evoked visual hallucinations. Each recording spans 21 seconds around the stimulation, with events annotated by stimulated contact pair, current intensity, and evoked effect, classified into 14 clinical categories. The data support identification of brain networks underlying visual symptoms and creation of symptom-related activation and connectivity maps.

Whole-night sleep recordings from 14 pre-surgical epilepsy patients (135.6 h in total), comprising a posterior hippocampal depth contact and scalp Cz recorded at 1 kHz. The derivative dataset repackages the authors' released data into BIDS and includes sleep scoring, artifact intervals, and automated ripple and spindle detections. It supports investigation of hippocampal-neocortical coupling between sleep spindles and long-duration ripples during sleep.

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 dataset from a registered replication study examining the psychometric properties of the error-related negativity (ERN) and error positivity (Pe) across multiple response-monitoring tasks. Raw EGI recordings were imported into EEGLAB, recoded into response-locked and stimulus-locked ERN/Pe event labels, and organized in BIDS format. The data support work on the reliability and construct validity of performance-monitoring event-related potentials.

Intracranial EEG (iEEG) recordings from 7 participants undergoing closed-loop, theta-synchronized stimulation of human hippocampal networks. The dataset accompanies a study showing that closed-loop control of theta oscillations enhances hippocampal network connectivity. Recordings are segmented into pre- and post-stimulation evoked potentials, pre- and post-stimulation rest, closed-loop stimulation, and control stimulation periods.

A longitudinal motor imagery brain-computer interface EEG dataset in which 20 healthy participants each completed seven sessions on separate days without feedback training. Four classes were recorded (left hand, right hand, both feet, rest) with a 41-channel Neuroscan system at 500 Hz, yielding 33,600 trials. The dataset supports research on the stability of motor imagery decoding across days and subjects.

Stereo-EEG recordings from six adult male patients with drug-resistant epilepsy performing a visual awareness task with saccadic report. Near-threshold Gabor gratings were presented while patients reported perception via saccade direction, enabling study of prefrontal cortex involvement in the emergence of visual awareness. The dataset includes per-trial behaviour, defaced T1 MRI, and source data with post-implantation CT and eye-position/behaviour files from patients and 10 healthy controls.

EEG recordings from 24 healthy participants performing a visual oddball (P300) event-related potential paradigm during mobile conditions: standing, walking, and running. Data were acquired with scalp and ear-EEG systems (73 channels, plus EOG) across five sessions per participant. This is a BIDS-formatted derivative of the Mobile BCI dataset, intended for benchmarking brain-computer interface decoding under locomotion.

This dataset contains 32-channel EEG recorded from 22 healthy participants performing visual imagery of ten cued items: animals (dog, bird, fish), geometric figures (pentagram, square, circle), and objects (scissor, watch, cup, chair). Each participant completed up to two sessions of three runs, giving 16,800 trials in total. It is intended for developing visual imagery-based brain-computer interfaces and is distributed in BIDS format with HED event annotations.
