A large-scale Spanish EEG dataset comprising 60 sessions from 56 healthy participants recorded using 64-channel EEG during speech perception and silent speech production tasks. Participants listened to and silently repeated 30 daily-use Spanish sentences. This dataset enables development of subject-independent deep neural network models for perceived sentence classification, with applications to speech decoding and neuroprosthetics for individuals with speech disorders.

This dataset comprises electroencephalography (EEG) recordings from 21 participants performing a dynamic ship-steering task under four noise conditions: no noise, environmental noise only, controller noise only, and combined environmental and controller noise. Participants controlled a centrally presented rotating arrow to maintain target orientation while experiencing manipulated levels of environmental and controller noise. The task employed unstable dynamics based on the pole-and-cart problem, with performance measured by proximity to target and crash avoidance. This dataset provides rich behavioral and neural data for investigating decision-making, motor control, and adaptation under uncertainty. Note: Participant 12 should be excluded from event-locked analyses due to bad triggers (trigger cable was partially disconnected). The reaction time for the first button press in each round is not recorded in the standard event markers but is available in the participantActions column.

This dataset contains EEG recordings from twenty-one participants performing a continuous feedback learning task in which they predicted the final height of an animated rising bar following different predictive cues. The task manipulated outcome predictability (highly predictable, somewhat predictable, unpredictable) using cued gnome stimuli, allowing investigation of neural correlates of continuous feedback and reward prediction processing.

This dataset contains EEG recordings from two experiments investigating the cortical encoding of sound source elevation in humans. Subjects were presented with noise bursts from loudspeakers positioned at various elevations in a hemi-anechoic chamber, and were also tested on their ability to localize elevated sound sources. Experiment I used a deviant detection paradigm, while Experiment II used a one-back task involving sound elevation discrimination.

This dataset contains EEG recordings from 16 participants viewing object images presented in eight different 2-D rotations, using rapid visual streams at two presentation rates (5 Hz and 20 Hz). The data support investigation of rotation-tolerant object representations and the time course of high-level visual object processing. EEG data are formatted according to the BIDS standard.

This dataset contains intracranial electrocorticography (ECoG) recordings of Cortico-Cortical Evoked Potentials (CCEPs) from 74 patients aged 4-51 years, collected during clinical single pulse electrical stimulation (SPES) as part of the RESPect epilepsy surgery patient registry at UMC Utrecht. The data were used to study the developmental trajectory of neural transmission speed across the human lifespan. Electrode positions were localized using Freesurfer with Destrieux atlas labeling and mapped to MNI152 space.

This dataset comprises EEG recordings from twenty participants performing a temporal scaling task involving learning of three temporal intervals. Two interleaved subtasks were used: a Production task, in which participants reproduced a short, medium, or long interval, and a Perception task, in which participants judged whether a computer-generated interval matched the target duration. Visual feedback (correct/incorrect) was provided after each trial in both tasks, enabling investigation of neural correlates of temporal interval learning and evaluation.

This dataset provides bimodal EEG and fMRI recordings acquired non-simultaneously during an inner-speech production task. Four healthy, right-handed participants silently produced eight words drawn from two semantic categories (social and numerical) across multiple trials. The dataset aims to support the development of speech prostheses and brain-computer interfaces by enabling multimodal fusion of high temporal (EEG) and high spatial (fMRI) resolution neuroimaging data.

This dataset comprises intracranial EEG (ECoG) recordings from 14 epilepsy patients implanted with subdural grid and depth electrodes, collected while they viewed grayscale and color visual stimuli varying in spatial and temporal properties. The recordings were designed to characterize temporal and spatial dynamics of neural responses in human visual cortex, including population receptive field mapping and category-selective responses. Pre-implantation T1-weighted MRI scans are also included for electrode localization. The dataset supports multiple published studies on visual cortical dynamics and adaptation.

This dataset presents EEG recordings from a randomized controlled trial examining the effects of forward and backward working memory span training on working memory performance. Event-related potentials were collected at pre-, mid-, and post-test sessions while participants performed a change detection task with varying target and distractor conditions. The study compares behavioral and ERP indices of working memory maintenance and interference control across training groups.
