Raw EEG recordings from 15 participants who each completed three auditory oddball sequences: the Optimum-1 paradigm for mismatch negativity (MMN), a learning-oddball paradigm for P3b, and the local–global paradigm for local and global effects. The dataset supports comparison of within-individual sensitivity of MMN and P3b effects across specialized oddball sequences and the local–global paradigm. Corrected event files, stimulation sequence definitions and stimulus presentation code are included.

This dataset contains EEG recordings from 24 pairs of participants performing a 4-way categorisation task based on rules they first agreed upon together. Participants also completed pre- and post-tests on the same stimuli. The data were collected to investigate how collaborative rule learning promotes information alignment between interacting brains.

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.

EEG recordings from 13 healthy participants performing a copy-spelling task with a visual 6x7 matrix ERP speller. The speller was designed for learning from label proportions (LLP), an unsupervised, calibrationless classification approach for ERP-based brain-computer interfaces. Two stimulus sequences with different target/non-target ratios allowed LLP to reconstruct mean target and non-target responses without labeled data. In the original online study, 84.5% of characters were spelled correctly on average without prior calibration.

EEG dataset investigating the neural time course of spontaneous face perception, including face pareidolia. Participants viewed 300 images of human faces, illusory faces, and matched non-face objects presented centrally at 3.75 Hz while performing an orthogonal target detection task. The study also involved behavioural tasks (odd-one-out dissimilarity, face-likeness ratings, and face/object categorisation) using the same stimuli.

EEG recordings from 24 participants viewing static images of moving and non-moving, natural and artificial objects. The study tests whether capacity for movement is an organisational principle in object representations, separate from aliveness or animacy. Participants completed a speeded classification task and a passive rapid serial visual presentation task. The dataset includes raw BrainVision data, preprocessed derivatives, decoding results, analysis code, and 400 CC0 stimulus images.

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.

A BIDS example dataset demonstrating annotation of intracranial EEG (iEEG) recordings with the HED schema library for SCORE (Standardized Computer-based Organized Reporting of EEG). It contains iEEG data from one subject recorded during clinical photic stimulation at Mayo Clinic. Events are annotated through an events.tsv column whose levels are defined as HED tags in the events.json sidecar, yielding machine-readable annotations validated with the BIDS and HED validators.

EEG dataset from twelve participants who completed three reinforcement learning tasks that differed in average task value. In each task, participants learned cue-response mappings for six coloured-shape cues, using left or right key presses. Cues had feedback validity of 0.5 (low-value) or 0.8 (high-value), and the tasks contained only low-value cues, only high-value cues, or a mix of both. The dataset supports investigation of how task-level value affects trial-level reward processing.

Intracranial EEG and behavioral event data from a paired associates learning task in which participants studied pairs of visually presented words, solved arithmetic distractor problems, and then performed cued recall. Data were collected from clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania. Recordings include monopolar and bipolar iEEG with subject-specific electrode montages, MNI/Talairach coordinates, and brain region annotations.
