This dataset contains simultaneous EEG and fMRI recordings from participants performing an inner speech task, in which eight words were presented in random order and repeated across trials. Data were acquired with a 3T MRI scanner and a 64-channel BrainProducts EEG system in three subjects across two sessions each. EEG data include pulse artifact removal and are organized in BIDS format.

A single-session EEG dataset of left- versus right-hand motor imagery recorded from 55 healthy, BCI-naive participants using a 16-channel g.Nautilus system at 250 Hz. Each participant completed one calibration run without feedback and three feedback runs, for 160 trials in total. The data were collected to examine psychological and cognitive predictors of motor-imagery brain-computer interface performance. This BIDS release was converted from the original DataverseNL deposit via MOABB.

Raw multimodal recordings of 18-channel EEG and functional near-infrared spectroscopy (fNIRS) from seven participants with orthopedic impairment performing motor imagery tasks. Each participant completed three sessions of 40 trials, with four motor imagery tasks (reach, twist, lift, grasp) presented in random order. The dataset supports research on multimodal brain-computer interfaces for people with motor impairments.

A BIDS-formatted high-density surface EMG (HDsEMG) dataset from 16 young volunteers performing submaximal (10-80% MVC) isometric ankle dorsiflexions (tibialis anterior, n=8) or knee extensions (vastus lateralis, n=8). Signals were recorded with four 64-electrode arrays (256 channels in total) together with force signals, supporting the decomposition of extensive motor unit samples and the study of rate coding. It is a BIDS conversion of the data from Avrillon et al. 2024, produced with the MUniverse software.

Raw 128-channel EEG data from 20 observers viewing object images in a rapid presentation paradigm, together with representational dissimilarity matrices. The dataset supports time-resolved neural decoding analyses that separate objects' contextual associations from their perceptual and conceptual attributes. One participant was excluded because of a technical recording error, leaving 19 usable participants.

A multi-paradigm motor-imagery EEG dataset recorded from healthy participants at Inner Mongolia University. It covers five body-part tasks (hand, foot, thumb, index finger, index-thumb pinch) with left/right laterality, performed under a Classic Arrow paradigm and a Cue-Execution dual-stage paradigm. This BIDS release is a public five-subject sample of a 244-participant dataset, recorded with a 64-channel Neuroscan system at 1000 Hz.

EEG dataset from an instruction-following study in which participants received novel verbal instructions combining integration or selection of animate and inanimate images, a relevant feature (color or shape), and a response key. Each participant completed a main instruction-following task and a 1-back localizer task in a single session. The dataset supports investigation of neural representations of novel instructions.

EEG, pupillometry, and behavioral data from 28 healthy adults performing an auditory fear conditioning paradigm with voice stimuli. Participants localized voices (left or right) across Pre-Conditioning, Conditioning, and Extinction phases, with conditioned voices paired with an aversive loud white noise using 50% partial reinforcement. The dataset supports research on emotional learning and auditory threat processing.

This dataset contains simultaneous electroencephalography (EEG), electrospinography (ESG), electroneurography (ENG), and electromyography (EMG) recordings from 40 participants, together with electrocardiographic and respiratory signals. Four conditions were recorded: resting state with eyes open, mixed median nerve stimulation, mixed tibial nerve stimulation, and alternating median/tibial stimulation. ESG electrode positions are provided for each participant. The study was pre-registered on OSF.
