A new study in mice suggests the hypothesis that brain-cleansing occurs during sleep may be inaccurate.
The findings show that mice cleaned more toxins and metabolites from their brains when they were awake than when they were asleep or anesthetized.
A long-term lack of sufficient sleep is linked to dementia and Alzheimer’s, but this new research suggests this is not due to brain clearing during sleep.
All mammals sleep, yet we are note entirely sure what benefits it provides.
Numerous theories exist, including processing the previous day’s memories. One idea that has gained wide acceptance is that during sleep, the body clears the brain of toxins and metabolite detritus.
A new study in mice finds that awake time cleans the brain more than when asleep or under anesthesia.
The study observed that 30% less fluorescent dye — standing in for toxins and metabolites — was cleared from the mice’s brains during sleep compared to when they were awake. When the mice were anesthetized, 50% less of the dye was cleared.
The researchers observed the rate at which the dye moved from the brain’s ventricles to other brain regions, making it possible to measure the degree to which the dye eventually passed out of the brain.
It is clear that humans often experience problems related to a lack of adequate sleep, ranging from a lack of mental sharpness and hand-to-eye coordination to serious health issues. However, the results of this study suggest that a lack of brain cleansing due to insufficient sleep is not the reason for these effects.
Thank you for the good writeup It in fact was a amusement account it Look advanced to far added agreeable from you However how could we communicate
