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

Area of Science:

• Neuroscience
• Cognitive Science
• Sleep Research

Background:

• Understanding spontaneous brain activity during different states is crucial for neuroscience.
• Simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) offer complementary insights into brain function.
• Existing datasets may not fully capture the dynamics of brain activity during both resting state and sleep.

Purpose of the Study:

• To introduce and describe a novel, publicly available dataset combining simultaneous EEG and fMRI recordings during human sleep and resting states.
• To facilitate research on brain activity patterns across distinct physiological and cognitive states.
• To provide a valuable resource for multimodal neuroimaging analysis.

Main Methods:

• Simultaneous acquisition of EEG and fMRI data from 33 healthy participants.
• Data collected during two resting-state sessions and multiple sleep sessions per participant.
• Expert sleep staging of EEG data performed by a Registered Polysomnographic Technologist.

Main Results:

• A comprehensive dataset of simultaneous EEG and fMRI signals during human sleep and rest is now publicly available on OpenNeuro.
• The dataset includes high-quality neuroimaging data and associated sleep stage information.
• This resource enables the investigation of brain activity across different states of consciousness.

Conclusions:

• The "Simultaneous EEG and fMRI signals during sleep from humans" dataset is a significant contribution to the field of neuroscience.
• It offers a unique opportunity to study brain dynamics using multimodal neuroimaging.
• This dataset will empower researchers to advance our understanding of spontaneous brain activity during sleep and wakefulness.
