Dataset of intracranial EEG during cortical stimulation evoking visual effects

ANAT iEEG

This dataset comprises intracranial EEG recordings from 22 patients with drug-resistant epilepsy undergoing stereo-EEG presurgical evaluation. It contains 115 high-frequency stimulation trials evoking visual hallucinations, with 21-second iEEG recordings per trial (8 seconds pre-stimulation, up to 5 seconds stimulation, 8 seconds post-stimulation). The dataset enables investigation of brain networks underlying visually evoked effects through alternating polarity biphasic pulse stimulation.

Multisensory Gamma Entrainment

EEG

This dataset comprises EEG recordings from a single healthy participant exposed to multisensory stimulation at gamma frequencies (40Hz). The experiment investigates brain entrainment responses to three stimulus modalities: auditory (5kHz carrier amplitude-modulated at 40Hz), visual (20Hz flickering white LED array), and combined audio-visual stimulation. Each stimulus epoch lasted 40 seconds and was recorded using 19 monopolar EEG channels at 500Hz sampling rate. The study aims to characterize synchronized brain oscillations induced by different sensory modalities, with potential implications for understanding gamma entrainment mechanisms relevant to neurodegenerative diseases such as Alzheimer's disease.

Human es-fMRI Resource: Concurrent deep-brain stimulation and whole-brain functional MRI

ANAT FMAP FUNC iEEG

This dataset comprises concurrent deep-brain electrical stimulation and whole-brain functional MRI data from 26 patients with medically refractory epilepsy. Patients underwent intracranial electrode implantation for clinical purposes, with one or multiple electrode contacts stimulated during fMRI acquisition using block design protocols. The resource includes anatomical imaging (T1, T2), resting-state fMRI, electrical stimulation-fMRI (es-fMRI) scans, field maps, electrode coordinates, and stimulation parameters, along with preprocessed derivatives.

Dataset of intracranial EEG during cortical stimulations evoking negative motor responses

ANAT iEEG

This dataset comprises intracranial EEG recordings from 23 patients with drug-resistant epilepsy undergoing stereo-EEG presurgical evaluation. The dataset includes 41 high-frequency stimulation events that evoked negative motor responses, with 24-second iEEG recordings per stimulation event (9-10 seconds pre-stimulation, up to 5 seconds stimulation, and 9-10 seconds post-stimulation). Stimulation parameters, contact pairs, current intensities, and evoked effects are documented in event files, enabling analysis of cortical responses to electrical stimulation.

Synchronous EEG and fMRI dataset on inner speech

ANAT EEG FUNC

This dataset comprises simultaneous EEG-fMRI recordings from 3 subjects across 2 sessions during inner speech tasks. Data were acquired using a 3T MRI scanner and 64-channel BrainProducts EEG system with EEG sampling at 5000 Hz and fMRI TR of 2s. The dataset includes preprocessed EEG with pulse artifact removal and is organized in BIDS format to facilitate multimodal neuroimaging analysis of inner speech mechanisms. This is a BIDS-converted version derived from OpenNeuro dataset ds006033.

40Hz Auditory Entrainment

EEG

This dataset comprises EEG recordings from elderly dementia patients during 40Hz auditory entrainment sessions designed to investigate the effects of gamma-band brain stimulation on neural oscillations. Participants underwent either short (6 trials) or long (10 trials) sessions of auditory stimulation while 19-channel EEG was recorded at 250Hz. The study examines whether auditory entrainment enhances default mode network connectivity through non-invasive acoustic brain stimulation.
