This dataset contains behavioral events and intracranial EEG recordings from a delayed free recall task in which participants studied visually presented word lists, completed arithmetic distractor problems, and then freely recalled the words. Open-loop electrical stimulation was delivered during encoding to single electrodes in the hippocampus and entorhinal cortex, on alternating two-word blocks in 20 of 25 lists per session. Data were collected at multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania.

Raw magnetoencephalography (MEG) recordings from 23 healthy adults performing an n-item delayed temporal reproduction task. Participants held sequences of one or three empty auditory intervals in memory and then reproduced them by button press. The dataset also includes EOG, ECG, digitized head and electrode positions, a two-minute eyes-open resting-state recording, and individual anatomical MRI. It supports research on working memory dynamics, auditory processing, motor responses and resting activity.

This dataset contains fMRI, polysomnography (EEG/EMG/EOG), ECG and pulse oximetry, and behavioural data from a study of Targeted Memory Reactivation (TMR) during REM sleep and its effect on emotional reactivity. Participants rated the arousal of 48 affective images paired with matching sounds, and half of the sounds were cued during overnight REM sleep. Arousal ratings and heart rate deceleration were assessed at baseline, in an MRI scanner 48 hours later, and in an online follow-up two weeks after baseline.

This dataset contains EEG recordings from deaf readers who read sentences containing semantic and syntactic violations, used to assess sensitivity to semantic and syntactic information during reading. Event-related potentials were recorded while participants viewed 180 sentences presented word by word, including subject-verb agreement, semantic, double, and word-order violations alongside correct control sentences.

This dataset contains raw 64-channel EEG recorded simultaneously with electrocardiography, photoplethysmography, eye-tracking/pupillometry, and behavioral data from 124 healthy young adults. Recordings were made during a resting-state session (alternating eyes-closed and eyes-open blocks followed by passive cartoon viewing) and an adaptive verbal working memory digit-span task with serial recall. The dataset supports research on cognitive load, working memory, and psychophysiological correlates of mental effort.

Stereo-EEG recordings from 11 patients with medically refractory temporal lobe epilepsy at Sanbo Brain Hospital, Beijing. Data were collected during learning of object-location associations and during targeted memory reactivation (TMR) with sounds in NREM sleep. The dataset supports investigation of electrophysiological signatures, such as hippocampal ripples and spindles, that underlie variability in human memory consolidation. It is a lossless BIDS re-packaging of the authors' raw Zenodo release.

MEG dataset from 22 participants performing a visual working memory task in which two Gabor stimuli were presented and a retro-cue indicated which stimulus and attribute to maintain for comparison with a probe. Each participant was recorded in two MEG sessions, with a one-back control task and anatomical T1 MRI. The data support investigation of the distinct brain mechanisms of selecting and maintaining information in working memory.

This dataset contains 64-channel EEG recordings and behavioural ratings from four participants who read and evaluated 210 short English-language texts: Haiku, Senryu, and non-poetic control texts. Each text was rated on aesthetic appeal, vivid imagery, being moved, originality, and creativity. These participants' recordings were acquired in segments because of session interruptions and were concatenated during preprocessing. They are released as a companion to the main Poetry Assessment EEG Dataset 1 for completeness and transparency.

EEG dataset from a visual working memory experiment in which participants judged whether a probe grating was rotated clockwise or counterclockwise relative to a memorized orientation. Color cues either predicted a 90° segment of possible orientations or gave no information about orientation. The dataset supports investigation of how diffuse predictions stabilize and reshape neural codes during memory encoding.

Sleep EEG recordings from 34 participants who underwent Targeted Memory Reactivation (TMR) during sleep, collected to examine whether memory reactivation acts holistically on object memory. Event files describe the cueing sounds and the corresponding satellite objects, including blocked, interleaved, and uncued categories. The data are organized in BIDS format using the FieldTrip data2bids function.
