Dataset of intracranial EEG during cortical stimulation evoking visual effects

ANAT iEEG Zarr

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.

EEG Resting-state Microstates Correlates of Executive Functions

EEG Zarr

Resting-state EEG recordings from healthy young adults (165 recruited, 140 in the final sample) collected to test whether intrinsic brain spatio-temporal dynamics, measured as EEG microstates, relate to executive functions. Session 1 contains 5 minutes of alternating eyes-closed and eyes-open rest recorded with a 64-channel BioSemi system. Session 2 contains behavioral data from nine executive function tasks. The dataset supports correlating microstate metrics with mean z-scored executive function performance.

Rapid coordination of effective learning by the human hippocampus: intracranial EEG during scene recognition with eye tracking

iEEG

Stereo-EEG recordings from six patients with medically refractory epilepsy performing a scene recognition memory task with concurrent EyeLink eye tracking. The dataset accompanies a study of how the human hippocampus rapidly coordinates effective learning, and is a lossless iEEG-BIDS re-packaging of the authors' public Zenodo release. It includes electrode MNI coordinates, behavioural arrays, eye-tracking files and the authors' analysis code in sourcedata.

Mapping object space dimensions: new insights from temporal dynamics

EEG Zarr

This dataset contains raw EEG data in BIDS format from participants viewing object images, collected to map the dimensions of object space and examine their temporal dynamics. Source data include trial-level behavioral event files detailing what was shown on screen during the EEG session. The dataset accompanies a study on how object representations unfold over time.

Meta-rdk: Preprocessed EEG data

EEG Zarr fidelity issue

Preprocessed EEG recordings from 20 individuals with a schizophrenia spectrum disorder and 22 healthy control participants performing a visual motion discrimination task with confidence reporting. Motion coherence was adjusted per individual with a staircase procedure to equate performance between groups, allowing study of perceptual decision-making and metacognition in schizophrenia.
