EEG recordings from four participants performing motor imagery of the left hand, right hand, and feet, originally reported by Zhou et al. (2016) in a study on automated trial selection for motor imagery brain-computer interfaces. Each participant completed three sessions of two runs, giving 450 trials per subject. Data were recorded from 14 channels at 250 Hz and reformatted into BIDS from a MOABB-generated Zenodo version.

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.

An intracranial EEG (iEEG) dataset recorded from ten epilepsy patients undergoing invasive monitoring for seizure localization. Participants played five sessions of Speed Match, a visuomotor game on the Lumosity platform, during interictal recording. Continuous iEEG recordings are provided in EDF format with channel information and event markers for finger tapping.

EEG dataset investigating the sense of agency over movements produced by electrical muscle stimulation (electrically-actuated movements). It examines the illusion of agency when involuntary, externally actuated movements are experienced, and provides raw EEG recordings organized in BIDS format.

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.

A longitudinal MEG dataset investigating brain activity during early skill learning, overnight consolidation, and longer-term retention in 31 healthy right-handed adults. Participants performed a sequential finger tapping task with the non-dominant left hand across up to three MEG sessions (initial training, about 24 hours later, and about 30 days later), with resting-state scans before and after practice. Anatomical MRI, behavioral responses, eye tracking and pupillometry, and forearm EMG were also recorded and synchronized with MEG.

Open-loop EEG dataset of kinesthetic motor imagery of ankle dorsiflexion/plantarflexion alternated with relaxation, recorded from six healthy participants. Each participant completed two sessions, one with a static and one with a moving lower-limb exoskeleton. The recordings contain 28 EEG channels and 4 EOG channels sampled at 250 Hz. This is a BIDS re-release of the Zenodo deposit, produced via MOABB.

This dataset contains EEG recordings from a study testing whether theta transcranial alternating current stimulation (tACS) improves working memory. Participants received either 20 minutes of verum or sham stimulation (1 mA, 6 Hz, Fpz-CPz) and then performed working memory tasks requiring mental manipulation or simple retention of items. Resting-state EEG with eyes closed and eyes open was also recorded before the task.

A multi-session, multi-task EEG dataset for passive brain-computer interface research, collected from 15 healthy participants across two sessions. Recordings include resting state and three difficulty levels (easy, medium, difficult) of the MATB-II multitasking environment, recorded with 62 active electrodes at 500 Hz. The dataset supports cross-session and cross-subject mental workload estimation and neuroergonomics applications.

A derivative repackaging of the authors' public Dryad release accompanying Tong et al. (2021), containing figure-level arrays for panels of Figures 1-4. It includes epoched and band-filtered iEEG, micro-LFP from 96-channel Utah arrays, time-frequency power, ripple rasters and spike indices from the human anterior temporal lobe, recorded during a paired-associates verbal memory task in patients with drug-resistant epilepsy. The data support analyses showing that ripples reflect a spectrum of synchronous spiking activity. Raw continuous recordings are not included.
