pyFR: Delayed Free Recall of Word Lists, Preliminary Cognitive Electrophysiology Study

BEH iEEG Zarr

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 clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania. It is a preliminary cognitive electrophysiology study that precedes the FR1 and CatFR1 datasets.

AlphaDirection1: EEG, ECG, PPG in the resting state and working memory for sequentially and simultaneously presented digits

BEH EEG Zarr

Raw 64-channel EEG, ECG, PPG and behavioral recordings from 30 healthy young adults (18–32 years) during resting state and a verbal working memory digit-span task with serial recall. The resting session alternated eyes-closed and eyes-open blocks followed by passive cartoon viewing. In the working memory task, seven-digit sequences were presented visually either simultaneously or sequentially at different rates and with different inter-stimulus intervals, allowing study of how presentation mode affects neural oscillations and peripheral physiology.

Sosulski et al. 2019 — Online Optimization of Stimulation Speed in an Auditory Brain-Computer Interface under Time Constraints

EEG Zarr

EEG recordings from 13 healthy participants performing an auditory oddball (P300) paradigm with target (1000 Hz) and non-target (500 Hz) tones at stimulus onset asynchronies between 60 and 600 ms. The study evaluated closed-loop Bayesian optimization and random search to find each individual's best stimulation speed for maximizing classification performance of a regularized LDA. The data comprise 31-channel EEG sampled at 1000 Hz, with an optimization part and a validation part.

The effect of speech masking on the human subcortical response to continuous speech

EEG Zarr

EEG dataset of auditory brainstem responses (ABRs) recorded from 25 normal-hearing adults listening to continuous peaky speech from one to five simultaneous male talkers, plus click trains. The dataset was designed to characterize how speech masking affects subcortical neural encoding of naturally uttered speech. It includes raw BrainVision recordings, event files, and stimulus regressors.

Nieuwland et al. 2018: Multi-site N400 Replication Study

EEG Zarr

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.
