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 contains simultaneously recorded EEG and fMRI data from 22 adults aged 23 to 51 years, collected at the Nathan Kline Institute while participants watched naturalistic video stimuli. It also includes eye tracking, physiological (respiration) recordings, demographic information, and behavioral measures such as sleep and caffeine intake. The goal is to investigate the relationship between electrical brain activity and hemodynamic fluctuations.

Open-access EEG dataset from Experiment B of Shin et al. (2017), recorded alongside NIRS for hybrid brain-computer interface research. 29 healthy participants performed cued mental arithmetic (serial subtraction) versus resting-baseline trials across alternating sessions. This derivative release contains preprocessed 30-channel EEG (CAR, 0.5-50 Hz bandpass, ICA-based EOG rejection, 200 Hz) with HED event annotations, formatted for benchmarking single-trial classification in MOABB.

Local field potential (LFP) recordings collected from TgF344-AD rats, a transgenic model of Alzheimer's disease, at 6 months of age while the animals traversed a linear track. The dataset is organized in BIDS format and supports investigation of hippocampal network activity in early-stage Alzheimer's disease pathology.

Magnetoencephalography (MEG) recordings from participants with major depressive disorder and non-depressed controls performing a probabilistic selection reinforcement learning task. The dataset was collected to examine the Reward Positivity and related ventromedial frontal cortex activity during feedback processing. It includes 90 participants, 52 with MDD and 38 controls, all screened using the SCID interview. T1 anatomical and resting-state data are planned to be added in a later release.
