Simultaneous EEG and functional MRI data during rest and sleep from humans

Abstract

Here we describe a publicly available dataset titled “Simultaneous EEG and fMRI signals during sleep from humans” on the OpenNeuro platform. To investigate spontaneous brain activity across distinct brain states, electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) were simultaneously acquired from 33 healthy participants (age: 22.1±3.2 years; male/female: 17/16) during the resting state and sleep. The dataset consisted of two resting-state scanning sessions and several sleep sessions for each participant. In addition, sleep staging of the EEG data was performed by a Registered Polysomnographic Technologist and provided along with the EEG and fMRI data. This dataset provides an opportunity to examine spontaneous brain activity using multimodal neuroimaging signals.
