This dataset contains stereoelectroencephalography (sEEG) recordings from patients performing a forced two-choice response task in the epilepsy monitoring unit at Oregon Health & Science University. The data were analyzed in collaboration with the University of Oregon and were used to characterize movement-related oscillations in intracranial recordings. It is organized in BIDS format.

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.

A multi-modal neuroimaging dataset (XP1) with simultaneous 64-channel EEG and fMRI recorded while 10 participants performed right-hand kinaesthetic motor imagery with neurofeedback. Each participant completed motor localizer, pre- and post-training motor imagery runs, and three neurofeedback runs (EEG-only, fMRI-only, and bimodal EEG-fMRI). The release includes raw and preprocessed EEG, BOLD fMRI, anatomical data, and EEG and BOLD neurofeedback scores to support multi-modal data integration.

This dataset contains simultaneous EEG and fMRI recordings from participants performing an inner speech task, in which eight words were presented in random order and repeated across trials. Data were acquired with a 3T MRI scanner and a 64-channel BrainProducts EEG system in three subjects across two sessions each. EEG data include pulse artifact removal and are organized in BIDS format.

This dataset provides eyes-open scalp EEG recordings acquired during intermittent photic stimulation (5 to 30 Hz in 5 Hz steps) from 36 participants with Alzheimer's disease, 23 with frontotemporal dementia, and 29 healthy controls. It complements an earlier eyes-closed resting-state dataset of the same cohort, and participant numbers match between the two. Raw and preprocessed (filtered, ASR- and ICA-cleaned) recordings are provided in BIDS format alongside clinical MMSE scores and demographics.

EEG recordings from elderly participants with dementia during auditory gamma entrainment. The stimulus was a 5 kHz carrier tone amplitude-modulated with a 40 Hz pulse train, presented in alternating stimulation and silence blocks. The dataset also includes a one-minute eyes-open resting-state recording. It is intended for investigating how 40 Hz auditory stimulation affects brain oscillations in Alzheimer's disease and related dementia.

A multi-session dataset of simultaneous EEG-fMRI recorded from 24 healthy adults aged 18-35 while they performed a gradual-onset continuous performance task (GradCPT) and a resting-state condition with intermittent multidimensional experience sampling. The same protocol was repeated on two days. Carbon wire loop sensors in the EEG cap support artifact removal. The dataset also includes ECG, behavioral responses, and mental health surveys. It supports study of attentional fluctuations, mind-wandering, and the test-retest reliability of EEG-fMRI relationships.

This EEG dataset investigates neurobehavioral mechanisms linking childhood sexual abuse to problem drinking in women. Data were collected at Washington University School of Medicine in St. Louis from monozygotic twin pairs, with twin pairs identified by a shared FamilyID. Task descriptions, subject instructions, stimulus program code and visual stimuli are provided in the stimuli folder.

Resting-state electrocorticography (ECoG) recordings from 13 patients with epilepsy aged 3.4 to 33.9 years, acquired with subdural grids and strips (plus depth electrodes in some participants) during intracranial monitoring in Seattle. The data were collected to study how the alpha rhythm and intrinsic neural timescales develop across childhood and adolescence. They are re-packaged in iEEG-BIDS without signal processing from the authors' public Zenodo release.

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).
