This dataset contains behavioral events and intracranial EEG recordings from a categorized free recall task with open-loop electrical stimulation applied during encoding. Participants studied semantically organized word lists, performed arithmetic distractor tasks, and then freely recalled the words. Stimulation was delivered to single electrodes in the hippocampus or entorhinal cortex during word encoding on a subset of trials, with data collected across multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania.

This dataset contains intracranial EEG recordings and behavioral events from a delayed free recall task with open-loop electrical stimulation delivered during word encoding. Data were collected across multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania. Stimulation was applied to single electrodes in the hippocampus or entorhinal cortex during alternating two-word blocks in a subset of study lists, enabling investigation of stimulation effects on memory encoding.

The PREDICT dataset comprises electroencephalography (EEG) recordings collected to investigate predictive markers related to pain and sensorimotor processing across multiple participants and sessions. It is intended to support research into individual variability in cortical responses, contributing to studies of pain chronification and neural predictors of clinical outcomes. This dataset is mirrored on NEMAR from an original OpenNeuro release.

This dataset contains long-term intracranial EEG (iEEG) recordings from 13 patients with focal epilepsy, part of the larger RESPect registry collected at the University Medical Center Utrecht. Recordings include electrocorticography (5 patients) and stereo-electroencephalography (8 patients), organized according to the BIDS specification with detailed session and run metadata reflecting monitoring periods and clinical protocols such as SPESclin. The dataset supports investigations into structural and effective brain connectivity in focal epilepsy.

This dataset contains raw EEG recordings from 15 participants who each completed three auditory oddball paradigms within a single experimental session: the Optimum-1 sequence for mismatch negativity (MMN), the learning-oddball sequence for P3b, and the local-global paradigm for assessing local and global auditory novelty effects. The dataset was collected to compare within-individual sensitivity of MMN and P3b responses across these different oddball paradigms. It includes original stimulation triggers, corrected event files, and source stimulation sequence definitions used in the analysis.

This dataset contains EEG recordings collected to characterize visual fatigue induced by mixed reality stereo vision. Participants viewed resting and movement scenes designed to elicit varying degrees of visual fatigue while EEG was recorded from 24 scalp electrodes. The dataset supports both resting-state and task-state EEG analyses related to fatigue characterization under stereoscopic visual stimulation.

This dataset comprises stereoelectroencephalography (sEEG) recordings from epilepsy patients undergoing monitoring for seizure activity at Oregon Health & Science University. During monitoring, patients were presented with auditory and visual numerical stimuli that were either symbolic (Arabic numerals and spoken numbers) or non-symbolic (dot arrays and beeps), enabling investigation of numerical cognition and its neural representations in intracranial recordings.

This dataset contains behavioral events and intracranial electrophysiological recordings from a free recall task with repeated word items, collected across multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania. Participants studied lists of words presented visually, with items repeated at varying frequencies, and then freely recalled the words after a delay period. The dataset supports investigation of memory encoding and retrieval processes as a function of item repetition.

This dataset contains EEG recordings from a semantic conditioning task designed to investigate how contingency awareness influences neural responses during fear conditioning. The data support analyses relating conscious awareness of stimulus contingencies to electrophysiological markers of conditioned fear responses. The dataset was collected and shared to enable reanalysis and replication of findings related to fear learning and conditioning paradigms.

This dataset contains EEG recordings used to derive auditory brainstem responses (ABRs) to continuous, naturally uttered speech under varying levels of speech masking. Data were collected from 25 normal-hearing adult participants presented with click trains and 'peaky speech' stimuli from one to five simultaneously presented talkers at different signal-to-noise ratios. The study aims to characterize how masking affects subcortical neural encoding of speech in human listeners, building on prior methods for deriving speech-ABRs.
