This dataset contains raw EEG recordings from a visual discrimination task comparing individuals with schizophrenia spectrum disorders and healthy controls. Participants performed a motion coherence discrimination task with adaptive difficulty while reporting confidence in their perceptual decisions. The study investigates neural correlates of perceptual decision-making and metacognitive processes in schizophrenia.

A de-identified intracranial EEG dataset from 58 patients with drug-resistant epilepsy treated at the Hospital of the University of Pennsylvania. The dataset includes electrophysiological recordings from subdural grids, strips, depth electrodes (ECoG), and stereotactically-placed depth electrodes (SEEG), with electrode localizations in ICBM152 MNI space, clinically-determined seizure onset zones, and resection/ablation cavity segmentations. Both interictal and ictal periods are represented, providing a comprehensive resource for epilepsy research and surgical outcome prediction.

The Penn Electrophysiology of Encoding and Retrieval Study (PEERS) is a large-scale investigation of the behavioral and electrophysiological correlates of memory encoding and retrieval. The dataset comprises EEG recordings from over 300 subjects across three experiments (ltpFR, ltpFR2, and VFFR), totaling more than 7,000 ninety-minute memory testing sessions. Data were acquired using either 129-channel Geodesic Sensor Net or 128-channel BioSemi systems, providing a comprehensive resource for studying neural mechanisms of human memory.

This dataset contains 128-channel EEG recordings from 20 observers (19 included in final analysis) viewing object images at 3.33 Hz to investigate how contextual associations, perceptual attributes, and conceptual properties of objects are represented in neural activity. One participant was excluded due to a technical error in EEG recording. Time-resolved neural decoding was applied to disentangle these distinct representational dimensions from the EEG signals.

This dataset comprises synchronized electroencephalographic (EEG), autonomic physiological, and behavioral recordings acquired during an emotional word association task. Participants performed a lexical task involving fear-related concepts, selecting or generating words in response to prompts while neural activity, autonomic responses (electrodermal activity, blood volume pulse, interbeat interval, and skin temperature), and behavioral events were recorded. The dataset includes 8-channel EEG data sampled at 250 Hz alongside physiological signals from an Empatica E4 wristband, with semantic similarity measures between consecutive word responses. This is the enriched version of OpenNeuro dataset ds007955 with additional analysis and documentation. Note: Physiological data for participant 7 are unavailable due to a data acquisition error with the Empatica E4 recording system; EEG and behavioral data remain available for this participant.

This dataset comprises 64-channel resting-state EEG recordings from 608 healthy adults aged 20-70 years, collected as part of the Dortmund Vital Study. Recordings were obtained before and after a 2-hour cognitive task battery, with measurements at baseline (2016-2023) and approximately 5-year follow-up (starting 2021) for 208 participants. The study investigates spontaneous brain electrical activity across the adult lifespan to elucidate developmental trajectories and associations with cognitive aging.
