[ and 21 healthy controls. Recordings include steady-state visual evoked potential (SSVEP) and steady-state auditory evoked potential (SSAEP) tasks at 4 and 6 Hz, as well as eyes-open resting state. The data support analyses of cortical coherence abnormalities in migraine.
[. 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.
The Brain Treebank is a large-scale dataset of intracranial (stereo-EEG) recordings from 10 epilepsy patients who watched Hollywood movies. Signals were sampled at 2048 Hz from 1,688 electrodes in total, across 26 movie trials and about 43 hours of data. The movie audio was transcribed with manually annotated word onsets, and each transcript was parsed into Universal Dependencies syntax trees. This makes the dataset a resource for studying the neural basis of naturalistic language. This record provides the data in BIDS-iEEG format.
VEPCON is a multimodal BIDS dataset with high-density EEG, structural MRI and diffusion-weighted imaging from 20 participants. Visual evoked potentials were recorded during face versus scrambled-face discrimination and coherent versus incoherent motion discrimination. Derivatives include preprocessed single-trial EEG, FreeSurfer outputs, multi-scale brain parcellations (83 to 1015 regions), structural connectomes, and EEG source-imaging inverse solutions, supporting multimodal methods development and structure-function studies.
MEG and structural MRI recordings from adolescents with major depressive disorder and healthy controls, collected for a pre-registered study of electrophysiological correlates of mood and reward dynamics. It includes a monetary gambling mood induction task (task-mmi3), pre-processed with bad channels and segments marked, and a 10-minute unprocessed resting-state scan from the same session. Anatomical MRIs are defaced and include co-registered fiducial coordinates.
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.
