Intracranial EEG (iEEG) recordings acquired during an auditory naming task in which participants heard questions that either began or ended with a wh-interrogative word. The dataset is organized in BIDS format and supports investigation of the neural dynamics underlying language processing and naming. It is mirrored on NEMAR from OpenNeuro.

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.

ROAMM (Reading Observed At Mindless Moments) is a multimodal dataset of simultaneous EEG and eye-tracking recordings from 44 participants during naturalistic reading, with span-level mind-wandering annotations collected through a retrospective self-report paradigm. It serves as a benchmark for mind-wandering detection and EEG-to-text decoding, and supports research on how attention lapses degrade language decoding from brain activity. Synchronized machine-learning-ready data, reading stimuli and page-level comprehension scores are included.

A large-scale (N=356) multi-laboratory EEG replication of DeLong, Urbach & Kutas (2005), testing whether readers pre-activate the phonological form of upcoming nouns during sentence comprehension. Participants at nine UK laboratories read sentences word by word, with indefinite articles (a/an) preceding expected or unexpected nouns. The data show reliable N400 effects on target nouns but no statistically significant effect on the preceding articles, which challenges strong accounts of prediction. The release includes all subjects with available raw data and a flag marking those included in the original paper's analyses.

This dataset contains behavioral events and intracranial EEG recordings from a delayed free recall task in which participants studied visually presented word lists, solved arithmetic distractor problems, and then freely recalled the words. Data were collected at multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania. Monopolar and bipolar recordings are provided with subject-specific electrode montages, MNI/Talairach coordinates, and brain region annotations.

This dataset provides intracranial EEG recordings and behavioral events from a cued recall paired-associates memory task with open-loop electrical stimulation. Participants studied word pairs, completed an arithmetic distractor, and then performed cued recall. Stimulation was delivered to single hippocampal or entorhinal electrodes during either encoding or retrieval. Data were collected at clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania.

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 repeated-item free recall task. Participants studied visually presented word lists, each containing 27 encoding events drawn from 12 unique words repeated one, two, or three times. After a 7-second delay they freely recalled the words in any order. Data were collected at clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania.
