A multimodal dataset of human decision-making under risk and ambiguity from 53 healthy volunteers aged 18-31. It includes structural MRI (T1w, T2w, DWI), task fMRI, and concurrent EEG recorded during inhibitory transcranial magnetic stimulation over two parietal regions and the vertex. The data enable investigation of the role of the parietal cortex in ambiguity computations.

EEG dataset from 19 participants performing a visual P300 speller-like paradigm to assess how visual stimulus properties affect evoked responses and classification accuracy. Each participant completed three sessions with conditions varying the number of stimuli (4 to 9) and the flash type (standard flash versus a superimposed yellow smiling cartoon face). Recordings comprise 382 files from eight electrodes sampled at 256 Hz, with markers encoding trial phases and activated symbols.

This dataset contains behavioral events and intracranial EEG recordings from neurosurgical patients performing a categorized free recall task. Participants studied lists of words drawn from semantic categories, completed arithmetic distractors, and freely recalled the words. Open-loop electrical stimulation was delivered to hippocampal and entorhinal sites during alternating two-word blocks at encoding, with stimulation parameters recorded in the event files.

EEG dataset of a visual oddball (P300) task from the PURSUE project, collected in 2017 and 2018 from participants at three primarily undergraduate institutions in Southern California, Massachusetts, and Virginia. The task design follows the ERP CORE paradigm, and the dataset includes participant demographic information such as race.

EEG dataset from a visual search task eliciting the N2pc event-related potential, collected as part of the PURSUE project. Participants were recruited at three primarily undergraduate institutions (Southern California, Massachusetts, and Virginia) in 2017 and 2018. The task follows the ERP CORE paradigm.

EEG dataset from a visual working memory experiment in which participants judged whether a probe grating was rotated clockwise or counterclockwise relative to a memorized orientation. Color cues either predicted a 90° segment of possible orientations or gave no information about orientation. The dataset supports investigation of how diffuse predictions stabilize and reshape neural codes during memory encoding.

This dataset contains raw neuroimaging recordings collected with the Visual Attribute-Specific Contextual Trajectory Paradigm 2.0. The paradigm is used to study how the brain generates domain-general visual surprise signals and how their latency depends on the visual attribute that is violated. It accompanies a pre-print on attribute-dependent latency of visual surprise signals.

A multi-modal face processing dataset combining simultaneously recorded MEG and EEG with structural MRI from 18 participants. Participants viewed famous, unfamiliar, and scrambled faces and made a symmetry judgment by button press. The data are a curated repackaging of the MEEG portion of ds000117, with reorganized event logs, Hierarchical Event Descriptor (HED) annotations, and EEGLAB-format EEG.

Microwire local field potentials (400 Hz) from Behnke-Fried hybrid depth electrodes in 35 patients with drug-resistant epilepsy, recorded during a picture-based Sternberg working-memory task with load 1 or load 3. Recording sites include the hippocampus, amygdala, dorsal anterior cingulate cortex, pre-supplementary motor area and ventromedial prefrontal cortex. This is an iEEG-BIDS representation of the NWB data released on DANDI (000673) from the Daume et al. 2024 study, with signal values unchanged.

This dataset contains behavioral events and intracranial EEG recordings from epilepsy patients performing a spatial navigation memory task. Participants encoded object locations during guided navigation and later recalled them by self-navigating. Open-loop electrical stimulation was delivered to hippocampal and entorhinal electrodes during encoding on alternating, difficulty-matched trials, with no stimulation at retrieval.
