The Penn Electrophysiology of Encoding and Retrieval Study (PEERS) characterizes behavioral and electrophysiological correlates of memory encoding and retrieval in highly practiced individuals. Across five PEERS experiments, more than 300 subjects contributed over 7,000 ninety-minute memory testing sessions with EEG. This dataset includes three free recall experiments: ltpFR (PEERS1-3), ltpFR2 (PEERS4), and VFFR (PEERS5).

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.

Scalp EEG recordings from 36 healthy university students during eyes-closed rest and a serial-subtraction mental arithmetic task. The dataset supports study of EEG correlates of cognitive workload and mathematical cognition, with applications in mental workload assessment and brain-computer interfaces. Participants were split post hoc into good and bad counters based on the number of completed subtractions. This BIDS version was converted from the PhysioNet release.

Resting-state EEG recordings from healthy controls and individuals with first episode psychosis (FEP), representing the first of two independently collected samples. The dataset includes 5-minute resting recordings with a 60-channel 10-10 cap, plus phenotype data covering clinical, cognitive, and socioeconomic assessments. It supports investigation of resting-state cortical abnormalities in the early schizophrenia spectrum.

Resting-state EEG recordings from healthy controls and individuals with first episode psychosis (FEP), representing the second of two independently collected samples. The dataset includes 5-minute resting recordings acquired with a 60-channel 10-10 cap alongside an Elekta Neuromag Vectorview system, and a phenotype directory with clinical, cognitive, and socioeconomic assessments. Subjects who shared a montage with the first acquisition (Task 1) are excluded here.

An EEG and behavioural dataset in which participants viewed images of scenes (stairs) and rated either their aesthetic properties (beauty, complexity, interestingness) or their appropriateness for a reading or social activity. The dataset investigates cortical responses to environmental affordances and the intention to act. It includes raw EEG, behavioural ratings extracted from EEG events, and the full stimulus set with identifiable file names.

Intracranial EEG (stereo-EEG) recordings from 22 patients with drug-resistant epilepsy undergoing presurgical evaluation, capturing responses to 115 high-frequency intracranial electrical stimulations that evoked visual hallucinations. Each recording spans 21 seconds around the stimulation, with events annotated by stimulated contact pair, current intensity, and evoked effect, classified into 14 clinical categories. The data support identification of brain networks underlying visual symptoms and creation of symptom-related activation and connectivity maps.

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.

EEG recordings from healthy participants receiving laser-evoked painful stimulation at four individually calibrated intensities (NRS ratings of 2, 4, 6 and 8) applied to the left and right hand dorsum. Each participant completed 80 trials (8 conditions with 10 trials each) and rated the perceived pain intensity on a numerical rating scale after each stimulus. The dataset supports investigation of the neural encoding of pain intensity.

EEG-BIDS dataset of cue-locked EEG recordings and event annotations from 43 neurotypical adults performing a random-dot kinematogram motion discrimination task. The task dissociates low-level priors (implicitly learned tone-motion contingencies) from high-level priors (a cover story about tinted glasses) against a neutral baseline. The data support analyses of hierarchical priors with signal detection theory, drift-diffusion modeling, and occipital oscillatory and aperiodic EEG activity, alongside psychosis-proneness and psychological flexibility questionnaires.
