Zoning Out From Poor Sleep? A New Study Says That Can Be a Good Thing
MIT researchers found cerebrospinal fluid flow during wakefulness impairs attention after sleep loss, with 26 volunteers tested using EEG and fMRI in controlled lab conditions.
- On October 29, Massachusetts Institute of Technology researchers reported that brief attention failures during sleep loss coincide with cerebrospinal fluid flowing out of the brain, observed repeatedly in scans and published in Nature Neuroscience.
- Faced with lost sleep, the brain 'sneaks in' cleansing pulses by initiating cerebrospinal fluid flushing process during wakefulness, but sleep-deprived participants suffer impaired attention, researchers say.
- Inside an fMRI scanner, participants wore electroencephalogram caps and performed visual and auditory attention tasks while researchers tracked heart rate, breathing, and pupil diameter.
- Researchers say identifying the circuits could reveal how the brain control circuits reduce cognitive effects of sleep loss through a unified circuit linking attention and physiology.
- The study places CSF cleansing at the center of neuron health by showing cerebrospinal fluid flushing clears metabolic waste, while the noradrenergic system may coordinate attention and bodily states, lead author Zinong Yang says.
