Multisensory Gamma Entrainment

EEG

EEG dataset from a single healthy young adult examining how auditory, visual, and combined audio-visual stimulation entrain gamma-band brain oscillations. Gamma entrainment has been proposed as a therapeutic approach for Alzheimer's disease symptoms. The session consists of three 40-second stimulation epochs, using a 40 Hz amplitude-modulated auditory tone, a 20 Hz LED flicker, and both together.

Kojima et al. 2024 (Dataset A) — An auditory brain-computer interface based on selective attention to multiple tone streams

EEG Zarr

EEG dataset from 11 healthy participants performing a 3-class auditory brain-computer interface task based on auditory stream segregation. Musical tones forming three tone streams were presented to the right ear, and participants attended to one stream while counting target stimuli, which elicited P300 activity. Recordings comprise 64-channel EEG and 2-channel EOG at 1000 Hz. Classification based on Riemannian geometry achieved over 80% accuracy for five subjects and over 75% for nine subjects in 10-fold cross-validation.

Network of autoscopic hallucinations elicited by intracerebral stimulation of periventricular nodular heterotopia: SEEG during 43 Hz and single-pulse stimulation (1 patient)

ANAT iEEG

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.

Internal-external attention switching SEEG epochs, DMN and DAN channels, 25 epilepsy patients (Hammer et al. 2024)

iEEG

Stereo-EEG epochs from 25 patients with drug-resistant epilepsy undergoing presurgical monitoring, recorded while they alternated between an external-attention visual search task and an internal-attention autobiographical question task. Epochs span -4 to +4 s around each task switch (external-to-internal or internal-to-external). They are limited to bipolar channels assigned to the default mode network and dorsal attention network by the Yeo-7 atlas. This is a BIDS repackaging of the authors' preprocessed release. The physical unit of the signal is not stated by the authors; channels are labelled µV as a curator assumption.

iEEG during direct electrical stimulation of orbitofrontal and other sites (Rao, Sellers et al., 2018): continuous-stimulation and single-pulse recordings

iEEG

Intracranial EEG (ECoG grids/strips and stereo-EEG depth electrodes) from 17 adults undergoing inpatient seizure monitoring, recorded before, during and after continuous 100 Hz direct electrical stimulation of the lateral orbitofrontal cortex and other sites, as well as during single-pulse electrical stimulation. The accompanying study reported that unilateral lateral OFC stimulation acutely improved mood in participants with moderate-to-severe baseline depression symptoms and suppressed low-frequency OFC power. The dataset is converted to iEEG-BIDS from the original Dryad release.

HeartBEAM: Older Adult Resting State and Auditory Oddball Task EEG Data

EEG Zarr

EEG recordings from older adults during eyes-open and eyes-closed resting state and during passive and active auditory oddball tasks. Each participant was recorded under a control condition and an arousal condition induced by the threat of unpredictable shock. The data come from the HeartBEAM study and support research on locus coeruleus-noradrenaline system activity and arousal in aging.
