EEG recordings from participants performing three near-threshold visual detection tasks that differed in cue information: a no-cue task, a noninformative cue task (50% validity), and an informative cue task (100% validity). The dataset was collected to study how prestimulus alpha-band activity relates to perception of near-threshold visual stimuli. It is shared in BIDS format.

Stereo-EEG recordings from a single drug-resistant epilepsy patient with a right posterior temporal periventricular nodular heterotopia (PVNH). 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 Bern-Barcelona database contains 7500 pairs of intracranial EEG signals (3750 focal and 3750 non-focal) from five patients with pharmacoresistant temporal lobe epilepsy. Each pair consists of two neighbouring channels, recorded for 20 s at 512 Hz and drawn from seizure-free intervals, and the pairs have been used to study nonrandomness, nonlinear dependence and nonstationarity of EEG. This BIDS release is a lossless repackaging of the original published text files into BrainVision format. Patient identity is not retained, so all runs are pooled under a single pseudo-subject.

Stereo-EEG recordings from six adult male patients with drug-resistant epilepsy performing a visual awareness task with saccadic report. Near-threshold Gabor gratings were presented while patients reported perception via saccade direction, enabling study of prefrontal cortex involvement in the emergence of visual awareness. The dataset includes per-trial behaviour, defaced T1 MRI, and source data with post-implantation CT and eye-position/behaviour files from patients and 10 healthy controls.

Experiment 4 of the Brain, Body, and Behavior Dataset (BBBD) contains multimodal recordings from 43 participants who watched short educational videos across two sessions. In Session 1 (attentive), participants watched instructional videos with focus. Participants were instructed to watch 3 videos in one attentive condition and 3 different videos in a second attentive condition, and were tested on the videos in the second condition, answering 11 to 12 factual multiple-choice questions after each video. In Session 2 (distracted), the videos were repeated while participants silently counted backwards, and no questions were asked. EEG, EOG, ECG, respiration, pupil size, gaze, and head position were recorded, along with questionnaires including the ASRS adult ADHD checklist.

This dataset contains 64-channel EEG recorded at 1000 Hz from 31 healthy participants performing a row/column P300 speller task with 4L and 5L grid sizes. Each participant completed three sessions. It is the P300 component of a multimodal eye-BCI collection that also includes eye-tracking and high-speed video for analyzing ocular activity across BCI paradigms. Events are annotated with HED tags as Target and NonTarget flashes.

Preprocessed, epoched local field potentials from the ventral lateral thalamus of 11 essential tremor patients undergoing awake deep brain stimulation (DBS) surgery. Recordings were made from mapping-electrode macro rings or the implanted DBS lead while patients read aloud consonant-vowel-consonant words and nonwords. This derivative repackages the authors' Dryad release (non-re-referenced trials) into BIDS iEEG format, with trial tables and MNI electrode coordinates.

EEG recordings from nine end-users with central nervous system tissue damage (stroke or spinal cord injury) performing five cue-guided mental tasks: word association, mental subtraction, spatial navigation, right-hand motor imagery, and feet motor imagery. Data were recorded with 30 active EEG electrodes across two sessions per participant, on different days. The dataset supports brain-computer interface research on individually adapted imagery and binary classification of mental tasks.

EEG recordings from healthy participants receiving laser-evoked painful stimulation at four individually calibrated intensities (NRS ratings of 2, 4, 6 and 8) applied to the left and right hand dorsum. Each participant completed 80 trials (8 conditions with 10 trials each) and rated the perceived pain intensity on a numerical rating scale after each stimulus. The dataset supports investigation of the neural encoding of pain intensity.

Multimodal dataset of 31 participants watching five short educational videos while EEG, ECG, EOG, gaze, pupil size, blinks, saccades, and head motion were recorded. Each participant completed an attentive session, in which factual questions followed each video, and a distracted session, in which they silently counted backwards. Experiment 2 uses an incidental learning design, so participants did not know in advance that they would be tested. Questionnaire data, including stimulus-related questions and the ASRS adult ADHD checklist, are included.
