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.

EEG dataset investigating whether episodic future thinking can reduce temporal discounting. Participants described a series of personal future events and were then cued to think about these events while making intertemporal choices. They also rated the vividness of their mental imagery for each event.

This dataset provides behavioral events and intracranial EEG recordings from a categorized delayed free recall task. Participants studied visually presented word lists built from 25 semantic categories, completed arithmetic distractor problems, and then freely recalled the words. Each 12-word list contains pairs of same-category words from three categories. Data were collected at multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania.

EEG recordings from 31 participants performing a third-party moral judgment task embedded in a semantic congruency (N400) paradigm. Participants heard scenarios describing intentional or accidental harm and judged whether a final target word was congruent with the scenario. Agent intention and semantic congruency were manipulated orthogonally to examine the cognitive conflict triggered by moral judgment of accidental harm.

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.

This dataset contains behavioral events and intracranial electrophysiological (iEEG) recordings from a spatial navigation memory task. Participants encoded object locations during guided navigation learning trials and then recalled the locations by navigating to them during test trials. Data were collected at multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania.

EEG dataset from the PURSUE project of a face perception task designed to elicit the N170 event-related potential. Data were collected from participants at three primarily undergraduate institutions in Southern California, Massachusetts, and Virginia during 2017 and 2018. The task follows the ERP CORE paradigm, and the dataset includes participant race information.

ZuCo 1.0 is a BIDS-formatted dataset of simultaneous 128-channel EEG and eye-tracking recorded while adult native English speakers read natural sentences. Three reading tasks are included: sentiment reading of movie-review sentences, normal reading of Wikipedia sentences, and task-specific reading with semantic relation annotation. The dataset supports research on the neural and oculomotor correlates of natural language comprehension.

EEG recordings from 23 healthy young adults performing a modified Sternberg working memory task. Participants memorized a sequence of black letters while ignoring interspersed green letters, then judged whether a probe letter belonged to the memorized set and received auditory feedback. The dataset supports study of source-resolved frontal midline EEG dynamics during working memory encoding, maintenance, and retrieval, and is annotated with HED 8.0.0.
