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 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.

Raw 64-channel EEG, electrocardiography, photoplethysmography, pupillometry and behavioral data from 86 participants during 4 minutes of eyes-closed rest and a digit span serial recall task. Participants memorized or passively listened to auditory digit sequences of 5, 9, or 13 items. The dataset supports work on cognitive load discrimination, event-related and oscillatory dynamics during encoding and maintenance, and links between working memory, central and peripheral physiology.

This dataset contains behavioral events and electrophysiological (EEG) recordings from a hybrid spatial-navigation and free recall experiment in which participants act as couriers delivering items to stores in a virtual town and later recall their deliveries. Sessions were either read-only, used to collect training data, or closed-loop, in which classifier predictions of memory encoding were used to time stimulus presentation. It represents the non-invasive portion of a project aimed at improving memory through closed-loop stimulus timing optimization.

EEG dataset from a visual working memory experiment (Experiment 2) examining whether memory reactivation levels are affected by anticipated interference. Participants memorized 2 or 6 lateral objects, then performed either a dual task with distractors or a single fixation-only task during the delay, before selecting the cued object in a probe display. The data have been preprocessed; the preprocessing steps are described in the associated preprint and OSF repository (Experiment 2).

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.

Raw EEG recorded during a modified Sternberg verbal working memory task. Participants either simply retained letters or mentally manipulated them by alphabetization, at three memory loads of 5, 6, or 7 letters. Event markers label the baseline, encoding, delay, probe, and response periods for each task and load condition.

Microwire local field potentials (LFP) recorded from Behnke-Fried hybrid depth electrodes in 35 patients with drug-resistant epilepsy during a picture-based Sternberg working-memory task (load 1 or 3). Recording sites include the hippocampus, amygdala, dorsal anterior cingulate cortex, pre-supplementary motor area and ventromedial prefrontal cortex. This iEEG-BIDS representation converts the DANDI 000673 NWB release (400 Hz LFP) without altering signal values, and includes trial, TTL marker and stimulus presentation events.

Magnetoencephalography (MEG) recordings from participants listening to 16-item binary sound sequences of varying complexity, used to test a language-of-thought account of compression in human working memory. Sequences were defined by minimal description length (transition probabilities, chunking, or nested structures), and occasional deviant sounds probed participants' knowledge of each sequence. The data accompany a study reporting that MEG and fMRI responses scale with sequence complexity.

EEG dataset from a visual working memory interference task (Experiment 1) investigating whether memory reactivation levels are affected by anticipated interference. Participants memorized a cued target object among two lateral objects; interference objects were shown in half of the blocks, followed by a probe and feedback. Preprocessing steps are described in an accompanying preprint and OSF repository referenced by the dataset authors.
