THINGS-EEG2: A large and rich EEG dataset for modeling human visual object recognition

EEG Zarr

THINGS-EEG2 is a large EEG dataset from 10 participants who viewed 16,540 training images and 200 repeatedly presented test images from the THINGS database. Images were shown in rapid serial visual presentation at 5 Hz while 63-channel EEG was recorded at 1000 Hz across four sessions per subject. The dataset supports modeling of human visual object recognition and includes resting-state recordings, the authors' preprocessed epochs, and stimulus images.

Cued Recall of Paired Associates with Open-Loop Stimulation at Encoding or Retrieval

BEH iEEG Zarr

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.

Disentangling objects' contextual associations from perceptual and conceptual attributes using time-resolved neural decoding

EEG Zarr

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.

Dataset of intracranial EEG, scalp EEG and beamforming sources from epilepsy patients performing a verbal working memory task

EEG iEEG Zarr

This dataset contains simultaneously recorded scalp EEG and intracranial EEG (depth electrodes) from fifteen epilepsy patients undergoing intracranial monitoring while performing a modified Sternberg verbal working memory task. Encoding, maintenance, and recall are temporally separated. It includes electrode MNI coordinates with anatomical labels, trial-level behavioral information, and LCMV beamforming-reconstructed virtual sensor data for several cortical regions. The data support studies of working memory, connectivity, and replay of memory items.

EEG RKI

EEG Zarr

A collection of electroencephalography (EEG) recordings from 15 students (8 male, 7 female, aged 21-23) performing essay-writing tasks. The task was designed to assess cognitive conditions such as creativity, memory, and critical thinking under different generative AI interaction conditions. The dataset supports studies of brain connectivity during student learning processes with Gen-AI.

Paired Associates Learning: Memory for Word Pairs in Cued Recall

BEH iEEG Zarr

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.
