Simultaneous EEG and fMRI recordings from healthy volunteers who reported their confidence in the accuracy of decisions they either committed themselves or merely observed. The dataset supports analysis of postdecisional contributions to metacognition and includes raw fMRI, BrainVision EEG, T1 anatomical scans and field maps, along with preprocessed EEG and fMRI derivatives.

This dataset contains 62-channel EEG recordings from 18 healthy, right-handed participants performing motor imagery of eight multi-joint movements of the unilateral upper limb. The movements involve the hand, wrist, elbow and shoulder. Each participant completed 320 cue-based trials across 8 blocks, with 40 trials per class. The data support research on brain-computer interfaces for motor rehabilitation.

EEG recordings from twenty healthy right-handed adults exposed to tendon vibration of the left elbow, designed to separate the percept of illusory movement from plain vibratory sensation. Sixteen sensorimotor electrodes were recorded while biceps and triceps tendons were vibrated at 90/50 Hz (illusion of elbow extension) or both at 70 Hz (control, no illusion). Each participant completed three blocks of 72 randomized three-second stimulations.

EEG dataset from a visual working memory experiment (Experiment 2) examining whether memory reactivation levels are affected by anticipated interference. Participants memorized 2 or 6 lateral objects, then performed either a dual task with distractors or a single fixation-only task during the delay, before selecting the cued object in a probe display. The data have been preprocessed; the preprocessing steps are described in the associated preprint and OSF repository (Experiment 2).

Alljoined-1.6M is a large-scale EEG dataset of neural responses to rapid serial visual presentation of natural images from the THINGS database. It was recorded with a consumer-grade 32-channel EMOTIV FLEX2 system in 20 adult participants over four sessions each, yielding more than 1.6 million trials. The dataset was built to test whether deep-learning-based brain-computer interface and semantic decoding research can be done with affordable EEG hardware.

EEG dataset from 146 participants (98 with Parkinson's disease and 48 controls) performing a cross-modal oddball task collected between 2017 and 2021. Each trial presented simultaneous visual and auditory pre-cues, either standard or oddball, followed by a directional arrow GO cue requiring a response. The dataset supports investigation of midfrontal neural activity and cognitive dysfunction in Parkinson's disease.

Simultaneous electroencephalography (EEG), electrospinography (ESG), electroneurography (ENG) and electromyography (EMG) recordings from 26 participants, together with electrocardiographic and respiratory signals. Somatosensory evoked potentials were elicited by mixed nerve stimulation (median and tibial nerves) and sensory nerve stimulation of fingers and toes, alongside a resting-state condition with eyes open. ESG electrode positions are provided for each participant. The study was pre-registered on OSF.

EEG recordings from 23 participants performing a passive viewing task with partially occluded and subsequently uncovered scenes containing game pieces on a game board. Conditions varied the number of initially visible pieces (4 or 32) and the number of pieces revealed after the occluder was removed (0 to 32). The dataset supports investigation of neural responses to object numerosity in occluded and uncovered visual scenes.

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.

EEG recordings from 17 male participants performing a guided visual search task while simultaneously completing a binaurally presented auditory N-back task. The design includes a baseline condition in which the auditory stimuli were ignored, and dual-task conditions with N-back levels of 0, 1 and 2, which vary auditory working memory load. The dataset includes 64-channel BioSemi EEG with EOG and mastoid reference channels and is annotated with HED.
